Pool Heating

From small to large pools of around 150m³ With the exception of solar power the most efficient way to heat your pool is with an electric heat pump.

Working as a domestic Refrigerator/Freezer with a cold evaporator panel inside the fridge and the heat being dissipated with the cabinet back. With the heat pump it works backward, the heat is transferred into the flowing water in a heat exchanger and cold air expelled out of the unit.

In the UK with the weather conditions we have you can expect late spring and early autumn temperatures of around 15C a correctly specified swimming pool heat pump should produce a 27C pool temp quite easily.

One of the ratings of a Pool heat pump is the COP Coefficient of Performance. With the above air temperatures a good quality pool heat pump should have a COP of 4 to 6. For every 1kw of electricity input you can expect around 4kw of heating power as a minimum.

A standard pool heat pump will still produce heat into the water right down to 6/7C air temperature.  Lower than this and you are getting to what is termed “Extended Season” equipment, but of course this comes at a price.

There are two main types of swimming pool heat pumps. Standard on/off types with a simple thermostat that that switched the pump from off to 100% heating. Then there are the Inverter types, depending on how much heat is required a typical inverter pool heat pump can run from 100% of heat output down to 20% before it switches off. Therefore will use less electricity in this reduction. A super efficient heat pump.
