Ground Source Heat Pump Servicing

It is a requirement to maintain a manufacturers warranty to service a Ground Source Heat Pump (GSHP) annually. It is also a condition of the Renewable Heat Incentive (RHI) that your unit is operating effectively and the best way to do this is to ensure it is suitably maintained.
