SPN FEB 2011 EnergySaving

The demands for reducing the costs of running a swimming pool have never been higher. As the new ‘fuel and power’ building regulations take full effect, specialist companies are keen to offer pool owners as many energy saving options as possible
S
aving on the cost of running a swimming pool or hot tub is never going to be under the spotlight as much as over the next 12 months.
This year sees the triple impact of the first full
implications of the Government’s Part L building regulations based on ‘conservation of fuel and power’; the launch of a scheme helping commercial pool owners and managers working to a positive ‘balance sheet’ in environmental energy and costs and more added pressure and interest from pool owners to cut day to day energy costs of running a pool. Energy savings will be the big theme for 2011.
The specialist industry is having to work harder on green issues providing more energy saving products knowing there’s an ongoing need to offer consumers more reassurance on energy costs. The installation of a quality pool cover is still a
big headline on saving energy. Although the introduction last October of the revised Part L regulations did not include the mandatory provision for a pool cover, with around 70% of heat being lost from the pool surface, the focus on
pool covers is certain to increase. Trade association SPATA considers this a vital part of heat conservation for consumers to consider purchasing as part of a new build, or to fit retrospectively. Certainly every pool owner and manager wants
to know how to cut running costs. Pool covers, heat pumps, pumps which save on electricity, measuring, control and dosage, systems which reduce the use of water, treatment products and energy will all remain firmly in the spotlight. Automatic pool covers are all, excellent energy
savers and as a product range have caught the consumers’ attention. Covrex, available exclusively in the UK from
Fairlocks Pool Products, is an innovative product, and is no ordinary pool cover. It offers advantages over traditional PVC slatted covers in terms of insulation properties; the slats have a U-value of only 0.12 and will safeguard and maintain heat energy in the pool water for longer than standard pool covers. This heat retaining ability is due to the profile structures being manufactured from expanded PVC-foam, coextruded with

polyurethane. The profile exterior is high density PVC which has a super smooth finish so that as well as increased energy savings it also has the added advantage of preventing algae formation either above or below the water level. Fairlocks also have another energy saving
product in the form of the Heatinverter Heat Pump which can be up to six times more energy efficient than conventional types of heaters which use electricity, gas, or oil as fuel. The Heatinverter uses a rectifier to convert the
incoming AC current to DC and then uses Pulse- Width Modulation of the DC current within an inverter to produce AC current of a desired frequency. The speed of a brushless motor is synchronised to the frequency of the AC current making it possible for the Heatinverter compressor to be run at different speeds. A microcontroller then samples the ambient air temperature and adjusts the speed of the compressor appropriately. With an EnergyGuard pool cover from Aquaflex
your customer will eliminate water evaporation by over 98%, thus greatly reducing water consumption and water charges, as well as saving a vital natural resource. Research carried out in collaboration with the Brighton and London Metropolitan Universities proved that the evaporation loss in the UK for an average sized uncovered pool, 4m x 8m, is approximately 32,000 litres per year. The Aquaflex EnergyGuard cover also reduces

chemical degradation from photolysis. About 90% of chlorine consumed by outdoor pools is lost due to photolysis reaction. Additional cost savings will be made by using less pH plus/pH minus to correct any pH imbalance caused by algae. An Aquaflex EnergyGuard cover will eliminate evaporation and greatly reduce radiation. Heat retention tests carried out in collaboration with the Brighton and London Metropolitan Universities, showed conclusive energy savings of over 50%. This applied to oil,
