For a typical domestic installation, the costs of an Air Source system are significantly less than an equivalent Ground Source system. There are no expensive and disruptive groundworks whatsoever with an Air Source System, the unit simply stands outside the property and is connected directly to the central heating flow and return pipes.
As the outside air is always laden with solar energy, Air Source heat pumps can utilise this “free” energy to provide highly efficient heating and hot water – even at air temperatures as low as -25C. And because winters in the UK are relatively mild, these heat pumps will run year-after-year with very high efficiencies.
