Heat Pumps

Air Source 

Heat from the air is absorbed at low temperature into a refrigerant. This refrigerant then passes through a compressor where its temperature is increased, and transfers its higher temperature heat to the heating and hot water circuits of the house. There are two main types of air source heat pump systems. An air-to-water system distributes heat via your wet central heating system. Heat pumps work much more efficiently at a lower temperature than a standard boiler system would. This makes them more suitable for underfloor heating systems or larger radiators, which give out heat at lower temperatures over longer periods of time, or larger surface area. An air-to-air system produces warm air which is circulated by fans to heat your home, an air-to-air system is unlikely to provide you with hot water as well.

Ground Source

Heat from the ground is absorbed at low temperatures into a fluid inside a loop of pipe (a ground loop) buried underground. The fluid then passes through a compressor that raises it to a higher temperature, which can then heat water for the heating and hot water circuits of the house. The cooled ground-loop fluid passes back into the ground where it absorbs further energy from the ground in a continuous process as long as heating is required. Normally the loop is laid flat or coiled in trenches about a metre deep, but if there is not enough space in your garden you can install a vertical loops down into the ground to a depth of up to 100 metres for a typical domestic home. Heat pumps have some impact on the environment as they need electricity to run, but the heat they extract from the ground, the air, or water is constantly being renewed naturally.
