Air Source Heat Pumps

An air source heat pump extracts energy from the air outside the house in the same way that heat is extracted from the inside of a fridge.

How do air source heat pumps work?
An air source heat pump extracts energy from the air outside the house in the same way that heat is extracted from the inside of a fridge.

Heat from the air is absorbed by a fluid which is pumped through a heat exchanger. This fluid passes through a compressor, and is concentrated into a higher temperature, capable of heating water for the heating and hot water circuits of the house. The process then repeats.

The pump can extract heat from the air even when the outside temperature is below freezing.

Unlike gas or oil boilers, heat pumps deliver heat at lower temperatures over much longer periods. This means that radiators should never feel as hot to the touch as they would do when using a gas or oil boiler.
