what are heat pumps?
Simply put, heat pumps move energy from one place to another, either from a lower to a higher temperature, or from a higher to a lower temperature. Domestic and commercial heat pumps take heat from the atmosphere, water or ground and deliver it to the point of use (cooling follows the opposite process).
Heat pumps use little energy, generally showing an output of 3 or 4 times that of every unit input into the heat pump. They operate at 300% or 400% efficiency.
Heat pumps consist of 3 elements:
The pump pushes the liquid around the circuit and the evaporator and three additional elements, the compressor, the condensor and the expansion valve. The fluid converts from liquid to gas as the heat is absorbed, it then condenses back to liquid as the heat is used.
We use air source heat pumps, which as well as provided domestic hot water for washing and bathing can also be specified to provide space heating and are ideally suiting to underfloor heating systems if space heating is the requirement.
