Sizing of the heat pump :

The sizing of a heat pump is of the utmost importance in order to be able to enjoy all its advantages :

  • efficient heating.
  • fairly low power consumption.
  • better longevity.
  • silent operation.

On the other hand, when the power of the heat pump turns out to be quite low, this can lead to negative effects :

  • heating that is both long and inefficient.
  • high power consumption.
  • a limited lifespan.

The table below can serve as a guide in selecting the ideal power according to the volume of your pool and your region. These calculations take into account the existence of a bubble cover on the pool water surface, especially at night. Without cover, the power of the heat pump must be duplicated thanks to the heat losses to be expected.
