What size heat pump do I need for my above ground pool?

Below you will find a list of above ground pool sizes, along with the kW size of heat pump we would suggest you need to heat the pool.

We have made a number of assumptions when calculating the kW size recommended, these are as follows;

  • Hydro-S suitable for May to August – thermostatic cut-off below 8°C air temp.
  • Hydro-Pro and ProTeam suitable for April to September/October – thermostatic cut-off below 0°C (-5°C Hydro-Pro) air temp.
  • Pool is covered with suitable cover when not in use, ie. solar or bubble cover
  • Pool is uncovered for no more than two hours per day
  • Desired water temperature is 27°C
  • Average air temperature is 15°C
  • Above ground pool volume calculation based on filling to 80% capacity
  • Your pool pump meets the required flow rate (see heat pump spec’s)
  • Suggested kW is minimum recommended for pool volume
  • To offset heat loss from above ground pools, we base our suggested kW size on double the pool volume
