Heat pumps are by no means a strange invention. Similar in operation to a refrigerator, they absorb energy in the form of heat and moisture from outside air, upgrading this energy to a usable form of heat through the unique ability of their refrigeration circuit.
Calorex Heat Pump Efficiency
By careful design Calorex Heat Pumps are capable of providing your pool with up to five units of absorbed heat for every one unit paid for. Even on a cloudy cold day when the temperature may only be 10°C, they will give three units for every one consumed.
The diagram below illustrates the way in which a heat pump absorbs, upgrades and transfers heat from outside air to swimming pool water.
All Calorex heat pumps contain a fully sealed non-CFC refrigeration circuit which is specifically designed to operate as a swimming pool heat pump. This means that all components used in their construction are designed to give maximum efficiency at typical swimming pool temperatures. Furthermore, the choice of material and construction will give years of trouble free service.
