Calyenty Launch DIY Easy Install Power Box For Swimming Pool Heat Pumps, Heat Pumps and Air Conditioning Units

One of the challenges for Cayenty to supply their range of swimming pool heat pumps over a large geographical area, i.e. the whole of Europe has been the installations. We have gradually developed a network of dealers in many areas but the reality is that if we have a dealer for example in Malaga and our customer wants his heat pump installing in Granada the distance for our dealer to travel to install the heat pump is either too great, even though this roughly the same area of Spain or the cost for the client for the dealer to travel and install is to much.

It is also challenging for us to find decent dealers who have the right balance of commercial resource to sell the units and the right technical standard and indeed qualifications to offer a full installation service at the right level.

The answer for us has ben to develop the Easy Install Power Box and the Quick Fit By-Pass.

The power box is almost a plug and play, where the client needs to supply the same cable as the tails supplied with the box, to the length required and connect to the terminals on the heat pump and circulation pump and the other end to his power supply.

We also supply a lovely little made up compact water by-pass to simplify the water connections.

Consequently , self install of our heat pumps is now within the capability of anyone with a hacksaw and a screwdriver.

Below are some extracts from our marketing literature:

For the connection of Any heat pump up to a power consumption rating of 2.6kW – If your heat pump is of a greater rating than this please contact our technical department to verify the components are of the correct rating.

Calyenty have developed the easy install power box to enable owners of heat pumps to connect their new heater to the electricity supply quickly and simply, and minimizing on the need to employ the services of expensive qualified electrical engineers. This box is tough and waterproof.

The Calyenty Easy Install Power contains a differential for total peace of mind and safety when operating an electrical Heat Pump, for example in a swimming pool environment. This device detects any tiny change in current which may indicate danger and will cut the power immediately

The box also contains all the other automatic breaker components and devices necessary for the safe and reliable installation of a swimming pool heat pump or any other heat pump or air conditioning unit.

Preferably mount inside.This power box is configured to comply by European safety standards.

Calyenty installs first swimming pool heat pump inside!

Well we tried to pursuade him to do it otherwise, but being a stubborn Brisbanite he insisted, and hey, the client is always right, right?

A swimming pool heat pump is a bit like a fridge or an air conditioning unit, only in reverse, well when you want to heat the water they are anyway. This technology has been around for years, I had a comment left on one of my first blogs from an American who had had a heat pump for over 50 years! The great thing is that this technology has improved significantly recently which has made them perfect for pool heating, and indeed house and domestic hot water, although that’s a blog subject for another day.

The challenge is this: an 8m x 5m pool, which is about as small as they get in these parts, contains on average about 50 tonnes of water. Most people like to swim at temperatures of between 27 and 30 degrees C, and at this time of year at night it often drops to freezing and below.

Achieving this with gas, oil, or standard direct induction electrical heating is expensive, well if your budget dictates that over 300 euros a week is expensive it is anyway. So roll out the heat pump.

Calyenty heat pumps can reach efficiencies of up to 1:7. This means that for every unit of electricity that the unit consumes it can produce seven times the equivalent in joules of heat. We recommend for most regions of Spain and Portugal, where we have most of our customers that if you heat your pool between April and the middle of November you will keep a comfortable swimming temperature for roughly the equivalent running costs as one week using traditional fuel types!

How does it do that?

Well the energy consumption goes into running a fan and a compressor. The compressor compresses refrigerant gas that runs through a series of tubes that are built into the sides of the heat pump, this part of the unit is called the condenser. The fan draws ambient air across these tubes and the energy that is present in the air passes into the gas where it becomes very hot. This heat passes into the swimming pool water where the two meet in a chamber called a heat exchanger.

Simple. Well it works fine as long as there is plenty of ambient air to pass through the vanes of the unit, which is why we normally insist that they are positioned outside. But Australians being Australians like to give us poms a challenge now and again and we recently had just that when our valued customer insisted that his shiny new heat pump must be positioned inside a small machine room near the pool.

Well we’ve done it. As you can see from the pictures there is a large barred entry point for the air to enter the room and a big galvanised duct to exhaust the air out, so hopefully the heat pump isn’t going to recycle already cooled air - it goes live very soon, so we’ll soon find out.

Please customers, take our advise, Calyenty pool heaters are extremely quiet and very beautiful so really don’t need to be hidden away, put them somewhere where they can be admired, coveted even, and where they will work to the maximum of their potential efficiency!!

Heat pumps beat other methods hands down

January 04, 2009

Editor, the Record:

A recent letter has motivated me to write to further inform your readers of the choices for energy efficiency and environmental air quality.

A ground source heat pump can operate at an efficiency level of 400 percent to 500 percent; oil efficiency is about 95 percent efficient (best case scenario), propane 80 percent.

Ground source heat pumps use electricity, which can be produced on site via solar, and the end user can end up with no out-of-pocket expense to heat, cool, and get hot water.

The cost per million btu of energy are as follows: If oil costs $2.20 per gallon, the cost per million btu is $18.11; for propane at $1.80 it is $26.64; for electric resistance at $.12 kwh the cost is $35.17; for a ground source heat pump the cost per million btu at $.12kwh is $7.99.

I hope this will clear up the confusion of what the best technology is to heat and cool your home or business.

All About Swimming Pool Heaters

All About Swimming Pool Heaters

To extend the swimming season after summer has come and gone, many people are turning to swimming pool heaters. A heater is great to have, especially with colder days. If you’ve thought about buying a heater for your swimming pool, there are probably a lot of things that you’ve found yourself wondering.

When using a pool heater, you can adjust the temperature of your pool water to virtually any level that you are comfortable with. The recommended temperature for a pool is 78 degrees, although most people prefer to have their water just a bit warmer, around 80 degrees. The choice is up to you, as you can’t really go wrong with either of the two.

During the year, the sun can only get your pool water so hot for a somewhat brief period of time. When summer ends and things start to cool off, your heater can help you make swimming last longer. If you live in the north of Spain, such as the Costa Brava, Portugal, France or even the UK you can actually treble your swimming season. Those living in warmer climates, such as the Costa del Sol or the Costa Blanca Canaries or Balearic islands and other European Mediterranean countries such as Cyprus, Malta, Turkey and Italy can actually target the whole year swimming by using a heater with their pool, without it costing a fortune.

Even though you may be using a swimming pool heater, you should still invest in a swimming pool cover as well. A cover can help to protect against loss of heat from the pool, holding the heat of water inside the pool instead of letting it out. The fact is, a good cover that has plenty of insulation can actually reduce the amount of heat loss you experience with your water.

There are a few different types of heaters available, including propane or mains gas, direct induction electicity and oil. Direct induction electric heaters such as this are easily the least expensive to buy, but by far the most expensive to run over time. Oil is another way to heat your pool, and it is common in areas that you are unable to buy gas fired heaters, oil is also extremely expensive in Europe. Other pools choose to run off electricity. Electricity is a great way to heat your pool, although it can easily be the most expensive to run and take the most amount of time to properly maintain, unless you use an electrically powered heat pump which can convert each unit of electricity it consumes to over six times the calorific energy output utilised to heat the pool water.

Last but not least, there’s the solar pool heater. Solar heaters may sound like the ideal way to heat a pool for some, simply because it uses the sun to heat, helping to save money. Even though it may sound like the ideal way to heat a pool, it actually has quite a few disadvantages when you compare it to other types of heaters. You’ll discover one flaw when you go to purchase one - you’ll see that they cost nearly half the amount of your swimming pool!

Even though solar powered heaters sound the best, they truly aren’t. To get the most out of a solar powered heater you’ll need to have large electric pump, which can cost you quite a bit of money. The pump delivers the water from your pool to the solar panels, which will in turn heat up the water. Once you have finished setting up a solar powered heater, you’ll have invested thousands in it - which makes it something you should really try to avoid. They are also ineffective when the temperature starts to drop, can be hard to install, high costs to maintain and difficult to position in an effective place, and even if a suitable place can be found, often a roof, they are ugly and can ruin the appearance of your property.

In the world of swimming pool heaters, heat pumps remain the best and most cost efficient ways to heat a swimming pool. They won’t cost you a lot of money to purchase, and they are very user friendly and if used sensibly are inexpensive to run.

Childers wanted heated swimming pool at Aras and other pool news

By Lorna Reid

Tuesday December 30 2008

PLANS for a heated indoor swimming pool and squash court at Aras an Uachtarain were hatched early in the presidency of Erskine Childers.

Two months after his inauguration in June 1973, the president inquired about getting the sports facilities installed.

And, a month later, he asked Taoiseach Liam Cosgrave about having the use of a IR£16,000 Daimler with a retractable roof as his official car.

But it was his inquiry about a heated swimming pool which sent various departmental officials into a spin in the summer of 1973.

An estimate from the Office of Public Works, which was responsible for the Aras, quoted IR£100,000 for a large swimming pool, with running costs of IR£5,000 a year. The cost of a squash court was put at IR£8,000, but an internal memo from the Office of Public Works (OPW) to the Taoiseach’s department noted both the swimming pool and the squash court were outside the normal range of improvements for Aras an Uachtarain.

The OPW said the finance minister would have to sanction such amounts which had not been budgeted for in the OPW estimates for 1974 or 1975.

Although President Childers had the use of a Mercedes as a state car, he had noticed a review of a IR£16,000 Daimler in Autocar magazine and didn’t think it would be “a super expensive vehicle” for use as a presidential car.

He suggested to the Taoiseach that a car with a retractable roof, like the Daimler, would be suitable for him as he would have more visual contact with the people who came out to greet him on the streets.

But Mr Cosgrave told him a car with a retractable roof would cost IR£20,000, an expense which could not be justified, so he had to settle for a Mercedes.

Swimming pool ban stays for child porn man

Tuesday, December 30, 2008, 07:20 - thisisnottingham.co.uk

A JUDGE has refused to lift a ban on visiting swimming pools for a man who downloaded child pornography.

Ian Hancock, 42, was given a sexual offences prevention order for seven years after admitting making indecent images of children.

But he asked Judge Dudley Bennett, sitting at Nottingham Crown Court, not to include a clause banning him from swimming pools – as it was his “own leisure activity”.

But the judge refused, telling Hancock’s barrister: “I’ve tried cases before where paedophiles go to swimming pools.”

Judge Bennett told Hancock that he must accept the order, but could come back and ask again in the future if he can prove he has become less of a risk to children.

Hancock was arrested after police traced several nicknames being used in an internet chatroom to him. Police then found ten indecent images of children on his computer.

Pornographic images of children are rated in severity from level one to level five, and Hancock had images from all levels, the court was told.

“Analysis showed he was sophisticated in his use of software,” said prosecutor Jonathan Dee. “He had set up a programme to search for certain terms.”

When interviewed by police, Hancock admitted possessing the images and said he had a sexual interest in young girls aged from ten to 14.

Hancock, of Fylingdale Way, Wollaton, was given a three-year community order with supervision by the probation service, as well as the sexual offences prevention order.

The order bans him from having unsupervised contact with children or working with them, loitering near schools, going to playgrounds, leisure centres and swimming pools, and using the internet for anything other than work or study. DVT

It also bans him from owning a mobile phone with access to the internet. “If you breach this order you will undoubtedly get an immediate term of imprisonment,” added the judge.

He was looking at (”making”) ten images of children. There is no actual proof that he is likely to hurt a child, but rather that he has feelings that he is controlling by viewing images that may or may not involve illegal activity *a jury said that they were “indecent”.

No doubt a long line of do-gooding lawyers will be lining up to help this pervert get compensation for having his human rights breached.

He’ll probably win too !

The judge did the right thing to ban this monster from swimming baths , it should be for life. dirty b*$@rd.

“Passive Houses” — Heating without furnaces, and other heat pump world news

Hey, what if you could have a house that’s much friendlier to the environment and costs about a tenth as much to heat?

Swimming pool heating specialists

Swimming pool heating specialists

Even on the coldest nights in central Germany, Mr. Kaufmann’s new “passive house” and others of this design get all the heat and hot water they need from the amount of energy that would be needed to run a hair dryer. [...]

Using ultrathick insulation and complex doors and windows, the architect engineers a home encased in an airtight shell, so that barely any heat escapes and barely any cold seeps in. That means a passive house can be warmed not only by the sun, but also by the heat from appliances and even from occupants’ bodies.

The concept has been tried before, but failed because of problems with mold and stale air. A new air circulating system, in which cold air gong in is heated by the warm air going out, has solved this problem.

But the sophisticated windows and heat-exchange ventilation systems needed to make passive houses work properly are not readily available in the United States. So the construction of passive houses in the United States, at least initially, is likely to entail a higher price differential.

Moreover, the kinds of home construction popular in the United States are more difficult to adapt to the standard: residential buildings tend not to have built-in ventilation systems of any kind, and sliding windows are hard to seal.

Sounds like the sort of thing that some sort of big green infrastructure investment stimulus package might want to invest in.

I grew up visiting a lot of solar architecture-my dad designed them for decades-and I am still heavily involved in LEEDS developments now. Just a nomenclature issue FYI: you are describing a particular type of superinsulated extremely airtight home. Passive doesn’t mean “airtight” though that is an important aspect of it as convection leads to quick heat loss. A passive system can be as simple as a correctly placed slab under south facing skylights, which absorbs heat by day and releases it (passively, of course) in the evening. So my mom’s house (which is far from superinsulated) nonetheless requires very little supplementary heat to stay warm, courtesy of good design.

Heh. i’m sorry to say that we’re a long way from good design; in many areas it’s hard enough to get local builders to point the houses south! Superinsulated supertight homes are extremely energy efficient of course, but as with all things there are diminishing returns as you approach the best levels. And many of the things you can mainly do to reduce heating costs are things which many US home builders (and buyers) do not want to do: reduce floor size, reduce windows, etc.

January 2nd, 2009 at 11:33 am

How much more energy does a house like this cost to produce (both to produce the materials and to actually build it)?

Not to argue against the concept, but what are the actual costs to put it into practice?

Gar Lipow Writes:

Passivhaus is a European standard. Although the proper translation is “passive house”, it is not the same as what we think of as passive homes. It does include an air sealing standar, nor more than one air change every 1.5 hours. This has been around a while. Amory Lovins wrote about it in the 90s. And properly done, there has never been a problem with mold or air quality. If you look at my online book (available for free download on the website linked to my name) you will see it includes a very brief discussion of this. - published in 2004. Though I can’t claim any great prescience for discussing then, since (as I noted) Amory Lovins discussed it fairly extensively back in the 90s.

Yep, lots of McMansions built in my neighborhood. 3000 or 5000 sq. ft. on small lots, tall ceilings, lots of glass. My wife and I kept asking, “Who’s buying these? Where are they getting the money? Why? Who wants to clean all that? Is someone going to buy them down the line when they want to move out?” Turns out the answer to that last one is “Nobody”. Turns out the answer to “Where are they getting the money” is “From you and me, bailing out their ARMs and sub-prime mortgages.”

PG, energy efficiency on a house level (measured on a per-square-foot basis, for example) can be accomplished in large structures as well as small. In fact, I know plenty of people who are designing and building large LEED certified homes. It’s just that large structures are inherently wasteful, because the per-person energy use is so high.

Also, any tight house can have as much ventilation as you want, given the requirement to add fans. it’s just an issue of heat exchange capacity. Even a tight house will leak a bit, and in theory the exchanger will compensate for everything else (though you do need to be OK with the fan noise.)

Anyway, Amp: We’re not investing in it because we’re so very far away from it. t

Take something simple, like insulation. used to be that standard was 4″ studs w/ fiberglass and no sealing. Then we evolved to stuff openings with fiberglass. then, to some degree, 6″ studs. Now even the least competent folks will (or should) build with 6″ studs and 6″ of glass, and will foam the gaps (though they do a bad job.)

but of course that is not even close to a good insulative envelope. In my area, the current gold standard that takes cost into account is a 1/2″ - 1″ spray of foam (e.g. Icynene) which completely seals and also insulates, followed by 6″ of fiberglass, on a 6″ stud. more expensive jobs use icynene for the whole thing. Some wrap the entire outside with another 1-2″ of rigid foamboard. Some build with SIPs. But in the end you still have a HUGE number of people who are building to minimal code requirements.

The small lots probably are OK for passive houses, but the article said there shouldn’t be more than 500 sq ft for each person, and I’m sure tall ceilings are right out. Then again, within my family the square footages are appropriate to our climates: my spouse and I share a 600 sq. ft. apartment in NY, where the main concern is staying warm Oct - May; my parents share a house with ten times that square footage in Texas, where the main concern is staying cool April-Oct.

i grew up in Scandinavia, and can attest that building standards in at least that part of Europe differ considerably from what i’m seeing now in the northern midwest.

windows i remember from my youth were never sliding ones; they opened by pivoting on an axis, usually a horizontal one. they weren’t meant to open for ventilation — 1960’s and 70’s era construction (which was the sort of buildings i grew up in) usually had separate ventilation hatches in case you wanted fresh air, mounted by the side of the windows. (those swung open on a set of vertical hinges.)

forced-air heating was unheard of, houses were heated with hot-water radiators and oil furnaces. these days i understand electric heat pumps are getting popular either instead of, or as cost-saving supplements to, the oil burners, and the heating water pipes are getting installed directly in the floors now. the wikipedia page on passive houses mentions heat pumps using the ground for a heat sink; the same principle can be used with the outside air, too.

these houses weren’t exactly airtight, far from it, but they were sealed up enough that most of them had separate ventilation systems to keep the air fresh. these were similar to U.S. style forced-air ducts, but not used for heating, so the registers were usually ceiling-mounted.

my parents built their home in 1979, and it got a heat-exchange ventilation system. it’s hardly high tech, a bit of sheet metal separating the incoming fresh air from the outgoing stale air as they travel in opposite directions, the latter heating up the former. i’m sure technology must’ve improved since then, though. there was a flap valve you could flip to bypass the heat exchanger in summertime, so you wouldn’t overheat the house; in the USA, you’d probably switch between heat exchanger and air conditioner.

basically, a “passive house” is pretty much the same sort of house the Scandinavians were building back thirty-plus years ago, except with vastly improved insulation all around and a fancier, higher-tech heat exchanger on the ventilation system. oh, and it seems you can make do with less of a heating furnace, too, once you have those features. the main backdraw i remember was that the air got awfully dry in winter — which i suppose might have had something to do with the many months of sub-freezing weather…

Dianne, you can design around that. Shades work wonders. ;) So do deciduous trees, which are conveniently bare when you need lots of sun, and green when summer is hot. Also, the sun angles are different in winter/summer, so you can design fixed barriers which will let in more sun selectively in a single season.

You can also use a large thermal mass. It takes the ground a long time to heat up and cool down, so it lags behind the air temperature. As a result the ground conveniently is warmer than the air when it is winter outside, and the ground is cooler than the air when it is summer. You can run pipes through the ground and pick up free thermal energy almost just for the cost of the pump.

You can achieve surprisingly similar results just with a concrete slab in your home.
And so on.

Low-carbon living = improved quality of life
Posted by Cathy Debenham on 2 January 2009 at 4:21 pm

Part of the difficulty of encouraging people to invest in low-carbon living is the difficulty of imagining what it will be like. Too much of the media coverage paints a picture of deprivation and hair shirts, leaving us shivering at the thought, and tempted to stick our heads in the sand.

Now a more positive vision is available from the Energy Saving Trust. In a new publication, Emission Impossible? A vision for a low carbon lifestyle by 2050, it outlines how a low-carbon lifestyle could improve the quality of all of our lives with more comfortable homes and better travel choices just two of the examples.

So what might a low-carbon 2050 be like? Well toasty warm to start. All homes are ‘zero carbon’ by then, whenever they were built. So it’s not necessary to put on the heating for more than a few days a year. Thanks to a combination of insulation and microgeneration cold snaps, such as the one we’re currently experiencing, don’t lead to stories pensioners freezing because they can’t afford to turn on the heating.

Unlike the current complex options available, energy choice is simple in 2050. Carbon cost is what determines it. And we can all optimise what we use thanks to smart controls. There’s no need to look out for energy saving labels on products either - wasteful appliances are no longer available - everything is designed for maximum energy efficiency.

We’re buying products that are made to last, with minimum packaging, so there’s hardly any waste. What there is can be composted or recycled. Water efficiency is the norm, with rain water harvesting for washing clothes and flushing toilets.

We travel less, and when we do we use lower carbon options. And attitudes have changed. To be seen to waste energy is sure to get the neighbours tutting. It’s the new equivalent of drink-driving and society frowns on it.

Of course, it’s not enough just to have a vision. There are some hefty hurdles to cross before we achieve this - in attitudes, in costs, in challenging corporate power to name a few. But unless we can imagine it, how can we reach it. It’s great to see a start to the visioning put into the public domain. Please let us know your vision for low-carbon living … and any successes you’ve already had.

Registration of all backyard swimming pools brought in

December 14, 2008 12:00am Sunday Mail Australia

A statewide fencing standard for all pools, irrespective of a pool’s age and location, and the requirement of a pool safety certificate as part of a property sale where applicable, also will be investigated under proposed new legislation to be outlined by Queensland Premier Anna Bligh today.

It will be the biggest overhaul of the state’s pool safety laws in 20 years.

The move, which will affect all above-ground and inground pool owners across the state, comes as alarming statistics show existing laws have failed to significantly reduce the number of child drownings in Queensland pools.

Katherine and Andrew Plint, whose daughter Hannah drowned in their family pool last year, welcomed the new rules.

”This change will stop people losing loved ones to drownings,” Mr Plint said.

Today’s potentially life-saving announcement comes four days after what would have been the toddler’s fourth birthday.

The Plints launched Hannah’s Foundation in their daughter’s memory and have been campaigning for the changes since losing their two-year-old on October 4 last year.

”(But) this is just the tip of the iceberg,” Mrs Plint said.

”We would also like to see compulsory CPR.”

Mr Plint said he wanted insurance companies to look at giving discounts to homeowners who have their pools checked regularly.

Twenty-three children have drowned in domestic pools across the state in the past three years – two in the past seven days.

On Friday, Liam Allen, 3, drowned in a friend’s pool at Ipswich, while last Sunday, Townsville toddler Holly Roberts, also 3, used a plastic table to climb over the family’s pool fence and toppled into the water to her death.

Ms Bligh will today announce the formation of a pool safety taskforce of key stakeholders, including child safety and local government representatives, who will formulate revised pool safety policies to be put before State Parliament when it returns in the New Year.

Organisations including the Royal Life Saving Society of Australia, Kidsafe Australia, the Australian Institute of Building Surveyors and the Swimming Pool and Spa Association of Queensland, also will be invited to take part.

“We will be asking the committee a series of hard questions and their answers will lead to improved pool safety laws and new pool fencing standards that will be the best in the world,” Ms Bligh said.

Royal Lifesaving Society Queensland executive director Michael Darben praised the review as “a step forward.”

Keith Tognola, of Townsville, whose son Philip drowned in 2003, said he was glad the State Government had finally taken notice of the recommendation of the coroner investigating his son’s death.

“It’s a relief. It’s good to see they are doing something,” Mr Tognola said.

“There are just too many kids dying in pools.

”This (the review) has been a long time coming.”

The Premier’s announcement to toughen pool safety laws and clamp down on those who wilfully and accidentally violate them follows The Sunday Mail’s Safe Summer campaign over the past three months, calling for improved pool safety standards and increased awareness of the need for constant vigilance when children are near water.

Our Safe Summer investigations and reports put the spotlight on alarming levels of non-compliance of existing safety standards among pool owners around Queensland.

The campaign found as many as 40 per cent of the state’s 300,000 backyard swimming pools would likely fail a routine safety inspection, including thousands that have no working safety enclosure at all.

Ms Bligh said the pool safety advisory committee would be given a wide brief to examine all issues relating to pool safety, including the many confusing and conflicting laws across various councils.

Currently, there are more than 11 different standards in place for backyard pools in Queensland.

“The review will also address concerns that pool laws are not being adequately policed by local councils,” she said.

The committee’s report will be released for public comment before legislation is drafted, Ms Bligh said.

Swimming pool plea (Somerset County Gazette - By Lloyd Vaughan )

WEST Somerset lacks suitable facilities for local schoolchildren to learn how to swim, it was claimed this week.

Liz Stewart, who runs Otters Swim School out of Knights Templar First School, Watchet, said the area urgently needed a 25-metre pool with the required depth so youngsters could learn how to swim safely.

Provision for young swimmers has worsened in recent weeks following the shock announcement that Quantock Lodge swimming pool at Over Stowey was also set to close.

Mrs Stewart said she already had nearly 250 children in her ‘learn to swim’ programme but the latest casualty meant the number of children on her books looked set to rise further.

She said parents had already called her expressing an interest in her swimming group and was making arrangements to accommodate them.

Just last week the County Gazette printed pictures of the on-going demolition of Minehead’s Aquasplash swimming pool.

The Seaward Way facility closed in October 2007 after it sprang a leak and failed to reopen because the cash-strapped council could not afford running costs.

Mrs Stewart said pools at St Audries Bay Holiday Club and Knights Templar School where she teaches were ‘fabulous’ but lacked the size and depth needed to provide children with the highest level of tuition.

She added: “In West Somerset we are surrounded by water with numerous children and adults who don’t know how to swim safely.

“Knights Templar’s pool is fabulous but it needs a lot of work and funding, and then there’s St Audries pool which is only 12 ½m x 7m.

“We should spend all our energy and time trying to secure a 25-metre swimming pool here in West Somerset.”

Rebecca Adlington (We love her cos she’s a Derby fan!!!) says ‘I want to win’

Rebecca Adlington rips open a packet of cheese puffs and, with a blissful sigh, crunches her way towards a much darker and more interesting place. She talks quickly as she eats, paying homage to Strictly Come Dancing and her Jimmy Choo shoes before admitting how she would love to win tomorrow evening’s BBC Sports Personality of the Year award.

Adlington is funny and charming but, down in the cheese puff dregs, as words like “sacrifice” and “pain” start to crowd out the chitchat, it becomes possible to understand how a seemingly ordinary 19 year-old transformed herself into a sporting superstar by winning two gold medals at the Beijing Olympics.

Her anecdotes, drifting from the “lovely Gordon and Sarah [Brown]” to “beating my mum and Aldo Zilli on Ready Steady Cook”, are told with riotous good humour. But Adlington is far more interesting when she moves on to her real life, her swimming life.

“That’s why I would really, really love to win [tomorrow],” she says, “because I’m a swimmer. We all talk about the shoes and TV shows but it’s actually got nothing to do with that. It’s all about me and the pool. I think most people don’t understand what you have to do to swim at Olympic level. You can’t expect people to really ‘get’ it because they don’t see me in pieces just minutes before the biggest race of my life. They don’t see me when I drag myself up six mornings a week at 5am so that I can train so hard that I can’t even lift myself out of the pool.”

Adlington laughs, but her eyes glaze with concentration. “I’m a bit of a masochist,” she says. “I love the pain. As an athlete I feel guilty if I don’t push myself in the pool. That’s why I get such satisfaction after a fantastically hard training set. There’s such purity in swimming. None of us are doing this for the money, and before Beijing I was trying to live off £12,000 a year and pay for all my training expenses. You can’t do that so you go,” she puts on a girly voice, “‘Daddy - can you help me!’”

She now shares a flat in Nottingham with her boyfriend, the Scottish swimmer Andrew Mayor, but she and her father still argue over money. “We had another little thing last Saturday,” she says. “I went back to my parents to watch Strictly and I love Austin Healey. He’s brilliant. My sister phoned in a couple of votes for him and I said, ‘Go on, give me four votes for Austin.’ My mobile won’t let me call that number so my sister phoned in four more votes on dad’s phone. He got really stroppy. He said, ‘You’re costing me money, making all these silly calls!’ I took out £2 and said, ‘OK, dad, here you are! Get over it!’ I really went mad then. I voted 12 times for Austin - but he still got voted off.”

Adlington looks genuinely pained. “I love them to bits, these shows, but they’re all the same,” she says. “The favourite never wins. Everyone keeps telling me that I’m the favourite [in the BBC awards tomorrow] but I don’t think it’s going to happen. I’m not saying that to get the sympathy vote, but the favourite never wins; and can you actually imagine a swimmer getting it?”

In sporting terms it’s absurd to try and decide whether Adlington deserves tomorrow’s award more than the astonishingly gifted Lewis Hamilton, or than Chris Hoy, who won three Olympic golds as a sprint cyclist. But the BBC gong is ultimately a popularity contest, which is why the odds have narrowed in her favour at the expense of Hamilton, who lives as a tax exile in Switzerland with his pop-star girlfriend.

Adlington, by contrast, lives in Nottinghamshire. “We should get Lewis to come up to Mansfield,” Adlington says, grinning, “I’ll show him the sights.”

Of course, Hamilton dragged himself from a similarly unglamorous backdrop in Stevenage, Hertfordshire, to become formula one’s newest world champion. Hoy also laboured in obscurity for years before Beijing.

“I love Chris,” Adlington says, “and look at Ben Ainslie - who just won’t allow himself to be beaten in an Olympic boat. I sat next to him on the plane back and he was lovely. I kept thinking to myself, ‘Hmmm, Ben, you’re all man!

“I really think an Olympic athlete should win it this year, but when I first said that all the papers wrote that I hate Lewis Hamilton. I was, like, ‘What?’ I totally respect Lewis and he has had an amazing year. But the Olympics only come round once every four years and there’s no way Chris or me will be on next year’s shortlist. And you can bet that Lewis is going to win another world championship next year or the year after that.”

The bookies believe Adlington has inched ahead of Hamilton and Hoy - who will compete against each other tomorrow afternoon at Wembley in a gimmicky event titled the Race of Champions before being flown up to Liverpool by helicopter. Adlington is full of mock indignation when hearing that, in the event, Hoy will be on his bike and Hamilton in a speeding car as they “race” each other. “Why didn’t they build a swimming pool for me to bomb up and down while they’re on their bike and in the car? Hang on! What if they put me in a sidecar with Lewis? I’ll give that gorgeous girlfriend of his from the Pussycat Dolls a wave as we flash past.”

For all her easy humour, Adlington will face some of her own insecurities tomorrow evening. Even in the beautiful red dress she and her mum brought in Spain, and the gold Jimmy Choos the mayor of Mansfield gave her, “it will feel daunting. I’ll look a bit ‘minging’ next to Lewis’s Pussycat Doll. But I do love their new single.”

That very human vulnerability is different to the sickening doubts which engulfed her in Beijing. After Adlington had stunned everyone by winning gold in the 400m freestyle she endured a four-day wait before the 800m final - for which she had long harboured serious ambitions. Bill Furness, her gruff coach from Nottingham, told Adlington after the 800m heats that she would smash the longest-standing world record in swimming, which Janet Evans had set almost 19 years earlier.

Adlington shudders. “I told Bill not to say that. With 10 minutes left before the final I wanted to burst into tears. Then I thought I was going to be sick, or faint. I lay down, and Bill knows I never lie down. He says, ‘You all right, chick?’ He always calls me ‘chick’ and pats me on the head. ‘Bill,’ I say, ‘I’m gonna be sick.’ He says, ‘No, chick, it’s just your body getting ready to race.’”

Then, she says, with a little smile, “Something extraordinary happened. We were told to get to the call room, me and the other finalists, and up on the TV screen we watched Michael Phelps race that incredible 100m fly - where he won by the tip of his nail to get all eight golds. I forgot everything else as I watched him. I walked out afterwards and this calm came over me.”

As soon as she dived into the water, her nervousness turned to confidence. “I said to myself, ‘Let’s go for it - even if I end up dying in the pool.’ All the time, during racing, I’m thinking constantly, remembering what Bill shouts at me at 5.30 every morning: ‘Bring your right elbow up, keep kicking, focus on the turns!’ In the final I actually could see Bill. He had come down to the edge of the pool. Normally he’s churning his arms to encourage me and screaming, but this time, in the most important race of my life, he’s standing dead still. I’m thinking, ‘Oh my God! What does that mean?”

Furness was simply transfixed, watching a performance from his protege that he would later compare to some of the epic Olympic swims by Phelps or Mark Spitz. “Oh God,” Adlington says, blushing, when I mention their names, “I don’t know about that. But I’ve never swum as well as I did that day. After 400m Bill threw away the split times he had been writing on a scrap of paper. He said, ‘She’s got it!’”

That “it” was her second Olympic gold and a staggering new world record, two seconds faster than Evans’s time. So even if Hamilton or Hoy beat her tomorrow she will survive the fleeting heartache because this has been a year like no other for Adlington. Five months ago few of us had even heard of her and yet now, on every trip to the shops, she is besieged by people who think that they actually know her. “We went to buy our Christmas tree at B&Q this week and you would’ve thought I was bumping into my best friends. I don’t know a soul but they’re shouting, ‘Hiya, Becky, how’s the training?’ Weird.”

It’s easy to warm to Adlington and her stream of anecdotes, in which she relates how she button-holed the beleaguered Brown at No 10 and grilled him on the best method of insuring her gold medals, and how it was suggested that the soon-to-be renamed Becky Adlington Swimming Centre in Mansfield might be called “Becky Baths” instead. “I turned down ‘Becky Baths’,” she says. “It’s not got quite the right ring, has it?”

She is at her most effusive when describing how, on a dreamy day a couple of months ago, on October 7, she and Mayor moved into a flat in Nottingham together. “I live with a boy!” she yelps. Adlington and Mayor sound lost in both the first flush of love and the brutal realities of Olympic training. Getting up together every morning at 5am, to be flogged by the decidedly unromantic Furness, might sound an unusual way of cementing a 10-month-old relationship. But having missed out on Olympic qualification in Beijing by a second, Mayor has moved down from Newcastle upon Tyne to live with Adlington and train with Furness.

“Andy might be 22 but he complains that he looks like he’s 12,” she says. “He doesn’t. He’s lovely and he’s working incredibly hard, just like me. We both can’t wait for the London Olympics. We’re swimmers after all.”

Adlington might be a celebrity now but, above all else, she remains a supreme athlete. For that reason alone, Healey owes his greatest fan at least 12 votes tomorrow night.
Life and times of an Olympian

Making Use Of Robotlike Swimming Pool Cleaners - December 13th, 2008 by Ada Denis

n the first place, note that in spite of how well you presume its possible to clean your pool physically, there are numerous things swimming pool cleaners get rid of when sanitizing swimming pools that you cant when you clean your swimming pools physically.

If you are anyone that does not always like sanitizing your swimming pool, whether physically or making use of robotlike swimming pool cleaners, then procure a swimming pool cover which you can utilize to cover your swimming pool, therefore cutting short the time you ought to clean your swimming pool.

I wonder why lots of folks still hire professional pool cleaners to clean their swimming pools when there are robotlike pool cleaners nowadays which they can utilize to attain similar quality sanitizing that swimming pool cleaners will achieve.

One of the fine things about Internet discussion groups where owners of swimming pools share thoughts concerning how care for their swimming pools is this - it is likely to come upon a pool owner there who might perhaps need to sell his or her pool cleaner at less expensive price; move and shop from such individuals, but see to it that the cleaner is compatible with your swimming pool. The very best method to do your own independent investigation on the particular kind of swimming pool cleaner to procure would involve visiting as many swimming pool cleaner review web pages as possible; from these kinds of review web pages its possible to learn a lot about what other people who have used these swimming pool cleaners have to say.

It is certainly true that those folks who utilize swimming pool cleaners, specially those folks who take care of the germs in the pools, are bound to enjoy a lot better physical healthiness than those men or women who dont; this is because numerous germs in the swimming pools can affect folks making use of the swimming pool and make them unwell. I always love putting my robotic swimming pool cleaner to function then staying aside to view it do its wonders; at such moments I am filled with a type of awesome feeling of surprise and applaud the tremendous efforts of the creators that produced this.

If you are amazed about the requirements of any swimming pool cleaner before purchasing, take a long look at the manual (which you can read on the Internet from the makers site).

I prefer to procure the add-ons and also replacement parts for my swimming pool cleaner from the exact same dealer or source that I ordered the swimming pool cleaner from; this makes certain they give me the add-ons and even replacement parts which are compatible with the precise kind of swimming pool cleaner I have.

From all the foregone its clear that the very best swimming pool cleaner you will get depends upon you; if you certainly take the time to search you will uncover the very best swimming pool cleaner to utilize; dont be like those persons who just settle for and utilize any kind of swimming pool cleaner without doing numerous searches.

Is Your Dog Likely to Jump into Your New Swimming Pool? - Free Pet Care Advice, Tips and Information - 13 Dec, 2008 -

All breeds of dogs can swim, but that doesn’t address the dangers of pools. When the pool isn’t filled with people, the dog will very likely join them, muddy feet and all. When no one is in the yard, the dog may decide to go for a swim, and won’t be able to get out of the pool unless there are steps provided that it can handle. Empty pools are especially hacardous to dogs that may not realize the depth of the hole into which they might jump. If your pool doesn’t have a dog-proof security fence, make sure the pup is confined in its run or in the house when not on a least.

Curing Algae Problems in your Swimming Pool

I like to think of myself as quite well informed when it comes to the care and maintenance of swimming pools, after all I am the director of one of Europe’s leading pool heating companies, Calyenty. However last year I had an attack of black algae which nearly defeated me. Beating the problem taught me a lot and I can share with you here the lessons.

Firstly I will make the point of how to try to keep the algae from forming which is really basic good housekeeping (or pool keeping in this case). But, as I have experienced sometimes even with the best intentions, events conspire against even the most diligent and attentive pool keepers and you get the dreaded attack.

Here they are anyway: Equilibrium is key. Correct levels of Chlorine and pH are the most important. Don’t just bung it in. Measure the levels constantly, or at least once a week and dose according to the volume of water in your particular pool. Check again soon afterwards, to check you have the dose correct. Also check total pH occasionally and add Bicarbonate soda if required. Remember it is always far easier to keep a clean pool clean than to clean a dirty pool and expect it to remain clean.

The other big factor is filtration. As a rule of thumb, all the water in your pool must pass throught the filter at least once per day. You can work out from this how long you need to run your filter pump for. In most cases, during the swimming season, I would recommend that for an 8m x 4m pool with a 1kW pump to run the filter pump for eight hours per day. Also it is important to run the filter pump during the day. Most people mistakenly break the timing up into chunks and run it stop start for 24 hours a day. You usually bath during the day and this is when the vast majority of debris will be entering the pool. Also wind movement is usually greater during daylight hpours, so filter it out during the day. You can put a half hour break in after say four hours if you want to give the pump a rest, but even this is really unnecessary.

Onto the Algae

There are almost 22,000 known varieties of algae, so you can probably roughly double that number for all living strains. But for reasons of understanding and control we can shrink this list down to manageable categories grouped by colour, see below.

As there are so many strains of algae and because their spores are almost permanently present in the air, there is nothing a pool owner can do from preventing the spores from entering the water. The presence of spores combined with out of balance water, warm temperatures, sunlight and presence of nitrates and/or carbon dioxide.can result in a bloom. But despite their presence, it is mainly good pool maintenance practice that prevebts the spores from developing into an algae problem

The pool must be kept in a constant state of correct equilibrium for preventing the spores taking hold and developing into a visual algae bloom, photosynthesizing on the sides and surfaces of your pool. Remember clean water is much easier to keep clean. Once you have had a bad case of algae or other water problem, the filters and other equipment are contaminated and its harder to get back to perfect conditions.

Firstly I’ll describe the four main types of problem algae presents, followed by the steps to cure a problem and how to take measures to ensure that you don’t have the problem again.

Different types of Algae,

Green Algae:

Green is probably the most common algae, certainly to be found in Spain, Portugal, France and the rest of Europe. It can quickly appear in your pool following the pool loosing clarity from a lack of proper filtration and, or poor sanitation due to chemical imbalance. It is frequently found free floating in the water, although it also will cling to the walls. Once it starts to form the water will remain cloudy and will get worse without proper treatment. This clouding distinguishes the problem as due to algae as apart form copper precipitation, which turns the water a clear green colour t. Varieties of green algae also appear as “spots” on surfaces, particularly rough areas, or places where circulation is low. They also show up as “sheets”, where large wall sections, or even the entire pool, is coated in green slime!

Yellow Algae:

Yellow algae usually clings to the walls of the pool and is a mustardy colour. This variety is usually found on the shady side of the pool. It forms large patches in sheets, and can be difficult to eradicate completely. If you get a bloom of yellow algae it can be tremendously difficvult to get rid of. Frequently a pool owner can spend the entire season fighting yellow algae, and re-infection is common, often just when you think it is beaten. You will need to scrub the infected areas thouroughly preferably with a steel bristle brush, shock with Chloro rapide then filter, filter, filter, backwashing frequently to waste to flush out the spores.

Black Algae:

Black algae will appear as dark black or dark blue/green spots, It is clearly raised like small bumps or buds from where it is rooted on the side of the pool. This is a horror if you get infected and is a little like herpes to get rid of as it keeps coming back. Sometimes you really need to resort to drastic measures to get rid of this one. The main reason this strain is so difficult to get rid of is because the plant puts down deep roots into the grout between the tiles and unless you kill the roots it will justy come back within a few days as bad as before.

Pools that are near the sea and frequented by bathers that like to have a dip in the sea then enter the pool without washing the swim suite between dips, are most susceptible to this form of algae bloom, but again, good water treatment levels and filtration usually keep it at bay.

Pink Algae:

Pink algae is actually a bacteria, however falls squarely into this category for treatment and even appears as though it is an algae. This tends to form in corners or dead spots where the water circulation is not what it should be and therefore the movement and changing of chemicals is not so great.

Where you get a mild bloom of the green algae you can use anitalgicides to solve the problem. The more you spend the better the product and less you will need to use in a dose, but these will have little or no effect on the other types of algae once you have the problem. It is good practice to put a small amount of algicide into your pool once a week when everything seems perfect, this will help prevent getting a bloom in the first place.

Below I list products on the market which are supposed to help to get rid of your algae bloom once you have it in my opinion, none of these products work on anything other than a mild attack of green algae, see later for the best eradication methods

Algicides:

Potassium Tetraborate:
When added to the pool water in proper dosage, prevents algae from converting carbon dioxide into the fuel it needs for growth.

Chitin:

Not an algaecide (meaning to kill algae) per se, but its properties might be called algaestatic (that is, to prevent algae growth). Chitin has the ability to coagulate and remove a wide variety of suspended materials and impurities from the water. This allows the sanitizer to more effectively kill contaminants unobstructed. It also improves the effectiveness of the filtration equipment.

Algaecides and Algaestats:

1. Quaternary Ammonium Compounds:
A low grade type of algaecide, Quats, as they are called, will usually have “10″ somewhere on the bottle, representing 10% active ingredient. Although available at a lower cost, quats tend to produce a small amount of surface foaming. They are most effective as an algaestat, that is, as a prevention, not a cure.

2. Polymers:
Polymers are long, complicated chemical chains that behave in water both as an algaestat and an algaecide. They are available in percentage strength of 30 - 60%, are non foaming, and work well as general, all around algae treatments. Poly-Quats are a blended compound of polymer and quats.

3. Copper Based:
Copper is a proven algaecide and algaestat. Available in varying non foaming strength of 3 - 10%. It works very well on all types of algae, but it has the drawback of staining white plaster surfaces a light blue/green color if it precipitates out of solution. Most copper based algaecides are chelated, which means that agents have been added to prevent this, such as Lo-Chlor Algaecide.

4. Silver Based:
Silver has been shown to be an effective bacteriostat, which means that it works to prevent bacteria from reproducing. Non foaming and effective with pink algae. In high doses, reactions with sunlight can cause colloidal silver to deposit as black stains on white plaster. When using copper or silver algaecides, the use of a sequestering agent is recommended.

PLEASE NOTE IF YOU HAVE A SALT WATER POOL DO NOT USE ANY METAL BASED ALGICIDES.

Too late to prevent it…How do I kill algae?

For suspended green algae, shock the pool…hard. Put in as much hypochlorite as it takes to turn the pool a cloudy, bluish/gray color. Brush the walls and floors towards the main drain, with a wire brush head if possible – be careful using these you do not want to damage the grout or the finish on the tile surface, but these do shift the roots of the algae. Backwash the filter when the pressure gauge indicates the need (8 - 10 lbs. above clean reading, after backwashing.) Using a flocculent may be a good choice if the pool is extremely “swampy”. As you probably know floculant will clump all the suspended solids in the water and deposit it on the bottom. When you suck this up with the vacuum cleaner take the water directly to waste, do not make the mistake of false economy of trying to filter it out thgen backwash, just get rid of it all to drain.If you cannot see the bottom of the pool, and it is filled with leaves and debris, it may be wise to drain the pool, acid wash and refill it.

After the chlorine level has come down below 5 ppm, add an algaecide and brush the pool again. When it all settles, vacuum the pool (to waste, if possible). Check and re-balance the pool water if necessary.

For algae which is not suspended, but only clinging to the walls, follow the same advice above, first shock with brushing, then add an algaecide, brush again, vacuum to waste (preferred) or vacuum and then backwash the filter. Use of a steel bristled brush is recommended for algae on plaster pools (use nylon brush on vinyl). Filter, Filter, Filter!

For black algae, the brushing part is very important. You must tear through the protective layers so the chemicals can destroy the plant from the inside out. Pumice stones work well to knock off the heads of black algae. (Don’t forget to vacuum them up later, and vacuum clean to waste). Also effective on the black algae nodules is sprinkling granular trichlor over the spots (of course if they’re on the wall this is next to impossible). Rubbing the spots on the walls with a trichlor tablet or stick can also be effective to knock off the heads and get trichlor directly to the roots. Follow up with a dose of copper algaecide, or high strength polymers.

Having said all this, my experience was, once the black algae was there you will never isolate areas in the pool and shift it with brushing or concentrated treatments in localized spots. Basicallly you will need to empty the pool. When the pool is empty thoroughly wash all the surfaces with a jet washer. Next acid wash it completely then rest it for at least a week. You will also need to completely change the sand in the filter, and try and rinse all other pipework and filter equipment with acid (in Spain we are lucky to have the splendid product Salfumant which is great for these heavy jobs – just be careful how you handle it, because this is basically concentrated hydrochloric acid. ) Also respect your equipment with such chemicals as it is VERY corrosive and can damage things quickly. Remember you are only trying to harm the algae.

For good algae prevention, we need a combination of good filtration, sanitation and circulation. It may be time to consider changing the old pump and filter. It’s cheaper and easier to pay a little up front for more chemicals, electricity or better equipment than all the money and aggravation spent on fighting algae blooms.

Deep Faith and Heat in Manhattan

Today’s blog is a comment on the following article about the tapping of underground heat for the  General Theological Seminary of the Episcopal Church in Manhattan, published on the New York Time’s website earlier today.  The article raises some interesting issues in my opinion. Firstly this project again demonstrates the willingness for organisations to embrace the need to extract free energy from environment, in this instance the ground.  This seems to be a growing and encouraging trend.  For them it makes good economic sense even though the final budget more than doubled, and therefore the payback time also, finally at 19 years. As the Seminal has already been around for 200 years this cost and payback period  still seems reasonable.  Layered onto the fact that after this there costs will effectively be zero for fuel for them this all bares well.

However the article does raise some interesting counter questions.  The problem I see with this project is the depth that the shafts need to be drilled, 1500 to 1800 feet through clearly very hard rock.  This is probably one of the main reasons that the project costs escalated so much.  There are only a handful of organisations that can stand projects going so far over budget, and these usually only government departments, or religious groups .

The big worry for me if I had commissioned the project would be the ongoing maintenance costs of the shafts.  The drillers experienced drift of up to 35 feet by the end of the shaft during sinking, and many of the additional costs to the project allude to certain government departments having similar fears over the stability of such deep shafts, insisting on expensive monitoring equipment.  Any shift could block or damage the shaft so it is ineffective, and the cost of rectifying such faults would be significant.

This is clearly a special building with its own challenges and I have great respect for all involved for pulling it off.  It would be interesting to do a cost comparison now comparing the costs of the project with providing the same output requirements from super efficient air source heat pumps, our technology is already demonstrating remarkable results at operating temperatures down to minus 35 centigrade.

Contemplating Heaven, but Drilling Deep Down

Dining in the newly heated/cooled Seminary.

For millions of years, invisible streams of water have run deep in the earth below Manhattan at a constant temperature of 65 degrees, a source of energy that seems beyond exhaustion — and beyond reach. But eight months ago, a seminary in Chelsea began to pump water from those streams to heat its buildings in the winter and cool them in the summer.

“It’s forever noiseless, forever pollution-less, forever carbon-free,” said Maureen Burnley, the executive vice president of the General Theological Seminary of the Episcopal Church.

For the seminary, and now about 60 other places in Manhattan, the unseen bounty of the earth is being harvested by geothermal pumps. Manhattan is geologically suited for these deep wells. From a depth of 1,500 to 1,800 feet, the pumps deliver the consistently moderate temperatures of underground water to the surface, where it works like a refrigerant. It carries energy.

“In the summer, you take the heat from the buildings and put it in the ground,” Ms. Burnley said. “In the winter, you take the relative warmth of the ground and put it in the buildings.”

The challenge has been the hardness or density of the substrat and the depth required to drill.

So far, General Theological has drilled seven wells — or 150 to 180 stories deep, at least. The seminary has plans for 15 more. When the project is complete, it will be the largest system of geothermal pumps in the Northeast, said Carl Orio, the chairman of Water Energy Distributors, a consultant and contractor that worked on the project.

About five years ago, hthe Seminary commissioned a study on its physical plant, which was expensive to heat and impossible to cool.

“We wanted to come into the 21st century,” Ms. Burnley said. “We skipped the 20th century altogether. Thomas Edison himself wired this campus. We’ve got Edison Electric plaques all over the place.”

The initial plans did not call for geothermal pumps, but the seminary’s consultants recommended that they be considered. Conventional heating and cooling systems have a much lower installation cost, but require fuel. A study projected that the pumps would take about 9 years to pay for themselves after the entire system was installed. Now, the projection is 19 years.

“Because we’ve been here 200 years, this investment makes sense,” Ms. Burnley said. “It won’t be the five-year return on investment that businesses want, but that’s fine. We’re going to be around.”

To reach the 65-degree water, the seminary drilled far below the city’s Third Water Tunnel, which is about 500 feet down, and far below Cameron’s Line, the point where an oceanic plate smashed into the prehistoric North American continent.

The first phase of the project was estimated to cost $6 million, but ended up costing $9 million for heating and cooling capacity in 80,000 of the buildings’ 260,000 square feet, according to Dennis Frawley, who managed the project for the seminary.

The increase was almost entirely the result of monitoring demanded by various arms of 10 government agencies that were involved in oversight, he said. Some neighbors worried that the drilling would cause earthquakes. The city was particularly concerned about damage to its water tunnel.

“When we were first getting started, we had drilling companies that said, ‘You can start a well on 20th Street and by the time you get down 1,500 feet, you’ve drifted to 21st Street,’ ” Mr. Frawley said. “We were allowed 3 degrees of tolerance — we couldn’t drift more than 75 feet on 1,500. Some of our wells drifted 10 feet, some were 20 feet. The worst was a well that drifted 35 feet.”

Underground water in Manhattan flows generally to the south, said Frederick Stumm, a scientist with the United States Geological Survey who has done extensive mapping of the island to help the city plan the Third Water Tunnel.

“The rock has been sort of brutalized by continental collisions,” Mr. Stumm said. “The rock has been under stress over the years, and it creates patterns of fractures in the rock.” Ground water finds its way down into these fractures, which form a network.

And it’s not just water down there. “We encountered rubies at about 1,000 feet,” Ms. Burnley said.

The rubies, said Mr. Frawley, were formed into the rock. “Nothing in the way of a large scale,” he said. “We weren’t turning the seminary into the ‘Deadwood’ movie set.”

For precious gems, “it’s easier to go to Macy’s,” Ms. Burnley said.
