The Heat Source are MCS Accredited air source heat pump and ground source heat pump installers serving Lincolnshire and the East Midlands.

Both ground source heat pumps (where heat is extracted via pipes under the ground) and air source heat pumps (where heat is extracted from the air) are a proven, highly effective solution for domestic and commercial heating/hot water requirements … whatever the weather!

Heat pumps work by circulating a refrigerant that is expanded and compressed to efficiently extract heat from even sub-zero temperatures – they can extract heat even at temperatures as low as –20 °C.
