Air source heat pumps

Air source heat pumps are renewable heating systems that extract heat from the air and convert it into energy for your radiators or hot water system. Since these pumps run on electricity and not gas, they are a great way to heat your home whilst reducing your carbon emissions. For every unit (kWh) of grid electricity that goes into your heat pump, you get roughly 3-5 units of energy out. This is known as the Seasonal Coefficient of Performance, or SCOP for short. This is the magic of heat pumps.

The better your home is insulated, the higher the SCOP you obtain. In simple terms, this means that more heat will be generated throughout your home. It is vital that you accurately calculate your SCOP in order to sufficiently design a heat pump system that remains compliant with Building Regulations Part L. As experts in commercial heat pump installations, we can help you with this. Here at Leodis, we will always undertake a heat loss survey before submitting a formal proposal.
