A pool cover is the most effective way to reduce heat loss, a pool without a cover will lose 2-3 times more heat than a covered pool. A pool cover will dramatically reduce the running hours and running cost of a heat pump. A pool cover will also greatly reduce water loss from evaporation.

Heat pumps are designed for outdoor installation and should not be installed in enclosed areas such as a shed or garage. Recirculation of cold discharged air over the heat pump will greatly reduce the units heating capacity and efficiency. Heat pumps should also be installed as close as possible to the pool equipment to reduce heat loss through pipework.

Heat pumps use refrigeration technology to extract the heat from the ambient air and transfer it to the swimming pool water. Click Here

The initial start-up heating time will differ, depending on the size of the pool and the air temperature at the time that you are trying to heat your pool; other considerations affect the time also, but these are not as important. However, once your pool reaches the temperature you desire, the run time can be as little as only a few hours per day.

The COP is the Coefficient of Performance. It is the ratio of energy input to output. Eg a unit with a COP of 5 would provide 5 units of heat for every one consumed.
For example a heat pump with a COP of 5 would use about 4kw of electricity and output 20kw of heat (ie 5 x 4kw =20kw).

There are several reasons why you might choose a heat pump over solar pool heating, heat pumps can heat the pool all year if required, no need for unsightly solar absorber pipes on the roof taking up roof space. Running costs are often offset by solar pv power systems. No leaking pipes on roof damaging gutters. Fast and easy installation.

Heat pumps will heat a pool at a fraction of the cost of gas heating, no need to run a gas line to heater location which can be costly.

The performance of a heat pump will fluctuate depending on several variable factors

• Size of Pool
• Size of the heat pump
• Use of a pool cover
• Ambient air temperature
• Desired temperature

The power requirements of a heat pump vary depending on the input KW’s. Some heat pumps will plug into a standard 10 amp power outlet and others will require 15 amp power supply or possibly 3 phase.+

Most heat pumps will operate down to air temperatures of 10 degrees Celsius, it is recommended to operate a heat pump through the daylight hours when the ambient air is warmest.
