source heat pumps take heat from the air out­side, in­crease its tem­per­a­ture and use it inside the home. There are two types – air- to- air pumps and air- to- wa­ter pumps. The for­mer pro­duce warm ( and also cool) air and cir­cu­late it through fans. Air- towa­ter pumps sup­ply your home’s ( wet) cen­tral heat­ing sys­tem. Air source heat pumps can work at tem­per­a­tures as low as - 15 C out­side, but can be less ef­fec­tive when it’s colder than - 5 C, so, again, an­other form of heat­ing may be needed in win­ter.
