What is a Heat Pump
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.
Heat Pumps Are Not New Technology
Heat pumps are not new technology. Refrigeration has been around for many years as has air-conditioning.
A heat pump works in a si,ilar way to air conditioning except that it is capturing heat from the outside air and transferring it into your home.
Air source heat pumps absorb heat from the outside air. This heat can then be used to heat radiators, underfloor heating systems, or warm air convectors and hot water in your home.
An air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can get heat from the air even when the temperature is as low as -15° C. Heat pumps have some impact on the environment as they need electricity to run, but the heat they extract from the ground, air, or water is constantly being renewed naturally.
