The technology works by removing energy from a low temperature heat source – the outside air – and then upgrading it in the heat pump so that it can be used to heat or cool air or water inside a building. The whole process is powered from natural gas or LPG. The GAHP system can reduce costs dramatically when converting from traditional boiler technology, while significantly improving environmental performance – benefiting businesses and public sector organizations, as well as domestic consumers.
