Air Source & Ground Source Heat Pump Systems

The main difference between the two types of heat pumps is simply where they get the heat from.  Air source heat pumps (ASHPs) absorb heat from the air, whereas ground source heat pumps (GSHPs) absorb heat from the ground.

Heat pumps are an effective and energy efficient way to produce hot water to heat your home.  They work by absorbing heat from the environment and transferring it to a fluid, which is compressed to increase its temperature.  This heat is then transferred from the compressed fluid into the central heating system, to use for both heating and hot water.
