How They Work

Heat pumps use technology similar to air-conditioning units. They use a fan and compressor to take heat from the surrounding air and transfer it to your pool.

For every £1 that you spend on electricity with a heat pump, approximately £5 will go into your pool. The electricity to the heat pump simply powers the fan and compressor. The system takes heat from the surroundng air and transfers it to the pool using the refrigeration cycle.

YOU PAY FOR 1 UNIT OF ELECTRICITY AND YOU GET 5 to 7* UNITS OF HEAT FREE !!

At 1 a unit of electrical energy (you pay for) runs the compressor which sucks evaporating freon gas from the liquid filled evaporator tube. This causes a strong cooling effect (just like sweat evaporates from you skin & cools you off). The gas picks up four units of heat (FREE) from the air flowing over the outside of the evaporator tubes.

At 2 the compressor squeezes this gas, causing its temperature to climb above 200° F (93° C) Result: Five units of heat added to the gas.

At 3 the hot,high pressure gas flows through the inside of the condenser coil. The colder 80° F (26° C) pool water picks up the five units of heat from the freon which cools it down back to a warm liquid.

At 4 the warm liquid is forced through a valve. As it drops in pressure, it rapidly expands and becomes extremely cold liquid .This liquid flows back into the evaporator At 1 where it repeats the cycle
