Heat Pumps are a great alternative to heating your home using fossil fuels. There are three types of heat pumps; Ground source, Air source and Water source and they all work by extracting available heat from either the ground, air or water and then releasing it to either underfloor heating pipes, radiators or hot water systems at a higher temperature.
Heat Pumps work just the same as fridges and air conditioning units. Heat will always flow from a warmer source to a colder source so heat pumps take advantage of this by using a special fluid that constantly evaporates and condenses in a closed circuit that is controlled by valves and a compressor, to reverse this natural process.
Just like a fridge, heat pumps always need electricity to run but for every kw of electricity they consume they normally generate 2-4kw.
