Tony explains: “Heating with fossil fuels is getting increasingly expensive for swimming pool owners. Many privately financed lidos are feeling huge economic pressures to stay open. The latest evacuated tube technologies can provide maintenance of the pool temperature throughout the season, once the pool has been conventionally warmed up in the spring. “Combining solar water heating with air to air heat pumps can provide all year heating, however, unlike domestic hot water where high temperatures of about 60°C are required, the swimming pools only need to be heated up to about 27- 30°C.
“Typically one evacuated tube array with
3m2 will be needed for 12,000 litres of pool volume. The pool water does not pass the solar panels as the chemicals used for pool sanitation would corrode them. Tubular heat exchangers are normally used and work very efficiently. As soon as the panels are three degrees warmer than the pool water the solar system will warm up the pool during reasonable sunny days.”
Certikin has the answer in the shape of the X-Flow Solar Heating Kit – a highly efficient and environmentally friendly system which will raise and maintain temperatures throughout the swimming season. It can heat pool water to temperatures of 27-29 degrees centigrade and reduce pool heating costs by up to a staggering 75%.
So, given that the X-Flow Kit will heat a pool by up to 2 degrees centigrade per day without any additional cost for the customer, how does this ingenious device work? Using the pump that circulates pool water through the filter, water is diverted so that it flows through the small passages of the solar collectors. While passing through the collector, the water is warmed by the sun. This warm water flows directly back to the pool. Through the use of its unique X-channel technology the X-Flow Solar heating kit offers one of the fastest heating times currently available in the solar marketplace. Not only does the kit save you money but it also offers the most environmentally friendly way to heat your swimming pool. To automate the control function, customers are advised to purchase the X-Flow Solar Controller which will continually gauge both the solar collector and pool water temperatures and will switch the system on/off depending on the prevailing conditions. X-Flow solar kits are sized on a minimum 50% ratio in relation to the size of

the pool, for instance a 12 by 24 ft pool will require two X-Flow Kits.
Available exclusively from Procopi UK, “Solar Ripp heating systems are unique,” so says Procopi’s David Dahl. “The German designed and manufactured systems are custom made for each installation, in a matter of days. The solar collector tubing is supplied in long rolls that are cut to size on site and fitted into the
support brackets. The collectors can be fitted vertically, horizontally or at any angle. The manifolds for either side are purpose made to handle any number of tubes. As the tubes have gaps between them they do not catch the wind like the large panel type collectors, and are much easier to fit in place. Each system can therefore be designed and fitted to any convenient space, even a curved wall.” The majority of Solar Ripp’s component parts are manufactured from polypropylene and carry a lifetime warranty. The solar sensing system, water temperature probe, control panel and motorised valve complete the kit. This ensures that there is only water flow through the collector when there is solar gain. Procopi UK’s Solar Ripp systems are suitable for use on domestic or commercial pools. A solution perfect for above-ground pools is the ‘Solar Pod’ from Plastica. Simple to install and virtually maintenance free, these compact units feature ‘heat trap’ technology and a glass house effect captures energy within the ultra-clear polycarbonate dome and transfers heat to its polycarbonate heat exchanger. One Solar Pod is ideal for pools up to 4,500 litres of water and for larger pools, they can be installed as mutiple units.
The world’s traditional energy resources of coal, oil and natural gas, are being out stripped at an unsustainable rate. The UK pool industry must take advantage of the natural energy supplied by the elements that surround us and harness these free energies to drive heat energy into pool applications without draining the planets resources. Technological advancements in products like solar heating, ground or air source heat pumps and even bubble covers have progressed in leaps and bounds during the last decade.
These products can be used in conjunction with conventional swimming pool equipment whilst at the same time offering ecologically sound alternatives to pool owners. spn
CAPTURING AND KEEPING THE SUN’S ENERGY IS WHAT SOLAR IS ALL ABOUT. THERE ARE THREE WAYS TO ACCOMPLISH THIS:
• Passive solar design ensures that a building’s integral design and material captures the sun’s energy so reduces the need for artificial light and heating
• Active solar water heating converts solar radiation into heat, which can be used directly or stored. Solar photovoltaic (PV) panels or solar cells convert daylight
• Enough sunlight falls on the earth every minute to meet the world’s energy demands for an entire year
