<\/a><\/p>\n Heat pumps provide efficient, reliable methods of heating homes and buildings. Because they use much lower amounts of fossil fuels, they also help reduce carbon dioxide emissions and other greenhouse gas emissions.<\/p>\n A heat pump draws heat from the ground, or from outdoor air, and transports it to another location for heating water or air. The supply of heat from the ground and air is plentiful, free, and constantly renewing. Even though they need electricity to operate, they produce about three to four times the power they use. The term coefficient of performance<\/a> (COP) indicates the amount of heat produced for each unit of power used, and COP statistics can help you determine which system may be most beneficial for the domestic market.<\/p>\n Heat pumps are more efficient when used with underfloor heating systems in well-insulated, draught-free homes. They heat with lower temperatures and remain on for longer periods. When you touch them, radiators used with heat pumps do not feel as hot as those using gas or oil. Heat pumps require almost no maintenance and produce safe, clean heat.<\/p>\n Here\u2019s how ground source heat pumps work:<\/p>\n <\/a><\/p>\n Air source heat pumps have a few slight differences.\u00a0Installers use an evaporator coil to extract heat from air outside the home, and\u00a0attach the unit to an outside wall of the building (as in the picture above).<\/p>\n Each system has its own unique qualities, and homeowners must decide which types of heat pumps would be more suitable for their particular circumstances.<\/p>\n Your contractor can analyse your location and requirements to give you valuable assistance in choosing the best heat pump for your specific situation.<\/p>\n Dane Cross writes on behalf of Ardenham Energy<\/a>, a UK based provider of heat pumps and solar PV panels.<\/em><\/p>\n\n
