A heat pump, in this case a heat recovery chiller, moves or "pumps" the energy from the tanks to either reject to the atmosphere in the summer or into the building to heat it in the winter. Unlike an air source heat pump, the source energy in a SSHP is never below 32F (0C) which results in much higher COP''s.

The influence of the water storage tank size and the air source heat pump size on the energy saving potential of the energy storage heating system is investigated comprehensively. The results show that even a small water tank, i.e., 0.06 m 3 ~ 0.5 m 3, can reduce the start-stop loss of the air source heat pump effectively.

Our heat pumps start at £500 for a standard installation (including the government grant). For larger or more complex homes, costs will be higher, but nearly all our quotes are less than the national average of £5,565. Whilst heat pumps can be fitted in most UK homes, we''re not able to install them in all properties just yet.
