Heat Pumps

Heat Pumps work by extracting renewable heat from either the ground or the air, this is done using the same process as a common refrigerator. Cold air from inside the building is carried out from the building in a liquid called a refrigerant, this liquid evaporates in the outside unit expending the cold air and taking in heat, this vapour is then compressed and sent back into the building with its increased temperature, the heat is transferred into the building and the process starts again.

What to look for in a  Heat Pump

Coefficient of Power (CoP)

This is a measure of the efficiency of the Unit and usually this will range from 3-4. Put simply a unit with a CoP of  4 will produce 4kW of heating Power for a an input of 1 kW. The CoP is reduced. A CoP of 4 is sometimes referred to as an efficiency of 400%.

Ground Source Heat Pumps

These use solar energy naturally stored in soil, bedrock and groundwater as a heat source. They do require electricity to operate, but efficiently produce up to five times as much heat energy for every unit of electricity they use. The range comprises suitable products for a variety of buildings and heating requirements.

Air Source Heat Pumps

These units extract the latent heat in the air and unbelievably can still extract heat from air temperatures of down to -20 degrees Centigrade. There can be some degradation of performance at lower temperatures and for the few hours in the year when this means that the unit cannot provide the heating an electric back up Unit is usually included
