How heat pumps work
A heat pump is a device which uses the refrigeration cycle to capture heat from the air (air source heat pump) or the ground (ground source heat pump).
In an air source heat pump, a fan blows outside air accross a series of fins which contain refrigeration liquid.
Heat is absobed into the refrigeration liquid which turns it into a gas and then the gas is compressed by a compressor.
When the gas is compressed, the temperature increases rapidly. The hot gas is then passed through a heat exchanger to heat the water in your heating circuit.
The beauty of a heat pump is that for every 1kw of electricity they use, they will typically output around 4kw of heat int your property
This makes them around 400% efficient.
A typical modern gas boiler is around 90% efficient
Air to water source heat pumps
Air to air heat pumpsextract the heat from outside, boost it to the required level, and blow out hot air into a room, or through vents around the building. They can also be used for cooling (air conditioning). Air to air heat pumps are not eligible for the renewable heat incentive.
