Pool Heating With A GSHP

GSHP's are often used for heating swimming pools in preference to Air Source Heat Pumps because in winter when the heating requirement is greatest (indoor pools) the low external air temperatures lower the efficiency of Air Source Heat Pumps.

The design of any swimming pool heating is a job best left to an expert who should consider the following factors affecting heating requirements

  • Surface area
  • Depth
  • Indoor/Outdoor
  • Desired water temperature
  • Insulation of pool walls
  • Level of water table in ground where pool is
  • Presence/absence of floating cover

As a very rough guide the following table can be used although this is no substitute for careful design
