Newly built warehouse with built in offices are now entirely heated by 3x Caernarfon Air Source Heat Pumps. The wet heating system consists of fan convectors in the roof space to heat the storage areas, while radiators keep the offices at temperature. Opting for air source heat pumps over alternative fuels there is an estimated £6,000 to be saved on heating alone. This with the added benefit of the non – domestic RHI, payments of £2,500 a year for 20 years, has provided this property estimated savings over £8,000 a year.
