HEAT RETAINING SYSTEM CHANGES LIFE FOR IRELAND’S FIRST PURPOSE- BUILT PRIVATE SWIM SCHOOL


a natural oxygen purification system that uses electronic oxidisation technology to provide 100% protection from bacteria for bathers without the negative effects of using chlorine, bromine, or other water cleaning chemicals.


Polypool’s insulated pool panel construction ensures effective thermal insulation of the pool shell


Ireland’s first purpose-built private swim school is enjoying the energy saving benefits of Polypool’s heat- retaining pool panel system. Polypool has designed a bespoke hopper-style pool for the new Water School in West Cork as part of a complete commercial package. Specified for high bather usage, the 16m x 7m swimming pool includes a filtration system with fast water turnaround, high durability liner, humidification control, and system management via an electronic display panel with remote control. Polypool’s insulated pool panel construction enables easy installation and ensures effective thermal insulation of the pool shell, reducing heat lost into the surrounding ground, saving energy, and cutting


heating bills. The patented system retains up to 96% of heat that would normally be lost through the pool walls and floor using traditional construction methods. Experienced swimming instructor, Clive Seawright, who set up the Water School, says Polypool’s heat retention performance has exceeded his expectations. He comments: “The pool has an operating temperature of 30 degrees C and we had planned for a 2 degree heat loss during days when the pool is in constant use, but in fact we’re only losing 1 degree, resulting in an even greater saving on projected energy bills.”


Providing safe, chemical-free swimming conditions was another important requirement for the new Water School. Polypool recommended


Polypool was also able to advise the Water School on a cost-effective heating system. An open loop water- to-water heat pump system has been installed, which utilises a nearby river as a source of heat for producing hot water for the swimming pool, as well as the underfloor and air heating systems. Prior to opening the Water School, Clive Seawright offered private lessons in the municipal baths but found local facilities couldn’t match demand. “At one time I had a waiting list of 300,” he explains. “Now I can offer personal tuition for all ages – the oldest to date is an 87 year old! Polypool’s high quality system and ability to offer a complete service from start to finish, including pool design and all the associated plant, has played a huge part in the success of the school and I’m now teaching up to 700 children and adults a week to swim.” The complete Polypool solution is perfect for in-ground swimming pool projects for schools, spas, leisure clubs, and luxury domestic developments, and is particularly ideal for hydro-therapy pools where a


higher constant temperature needs to be maintained. Polypool’s engineers seek to be involved in the earliest stages of design to attend to such details as filtration inlets/outlets and under water lights. Manufacturing is scheduled to suit the project requirements, and delivery on site can be as little as two weeks from order. Installation may be carried out by a Polypool recommended contractor, or by any competent groundworks contractor with the assistance of Polypool’s site support engineers. Wall panels simply cam-lock together and are held in place by bottom and top tracks. In fact the structure is so simple to assemble, the company also has a successful track record supplying kits to the self-build project sector. With over 40 years of experience in swimming pool construction technology, Polypool already has a clear lead in insulated pool wall and panel systems that combine the benefits of affordability ease of installation, and effective heat conservation. Recent developments have given Polypool an expanded product range and better serviced network of dealers and installers.

POOLS TURN TO GEOTHERMAL ENERGY FOR HEATING


The heat in the upper six miles of the earth’s crust contains 50,000 times as much energy as found in the entire world’s oil and gas reserves combined. Over the last decade, geothermal energy has been growing at scarcely 3% a year. Its potential is now being sourced to heat swimming pools around the world. Hot underground water is widely used for both bathing and swimming. Japan has 2,800 spas, 5,500 public


bathhouses, and 15,600 hotels and inns that use geothermal hot water. Iceland uses geothermal energy to heat 135 public swimming pools, most of them year-round open-air pools. Hungary heats 1,200 swimming pools with geothermal energy.


Though it is still costly, this technology can be used almost anywhere to convert geothermal heat into electricity. Australia is currently the leader in developing


pilot plants using this technology, followed by Germany and France. To realise this potential fully for the United States, the MIT team estimated that the government would need to invest US$1bn in geothermal research and development in the years immediately ahead, roughly the cost of one coal-fired power plant. In Europe, Germany has five small geothermal power plants in operation and some 150 plants in


the pipeline. Werner Bussmann, head of the German Geothermal Association, says, “Geothermal sources could supply Germany’s electricity needs 600 times over.” If the four most populous countries located in the Pacific – the United States, Japan, China, and Indonesia – were to invest seriously in developing their geothermal resources, they could easily make this a leading world energy source.
