Which heat pump for my swimming pool?

The swimming pool

The first elements to take into account when choosing a model suitable for the swimming pool are:

• The volume of water in the pool (a 30 ^m3 pool does not require the same heat pump as a 50 ^m3 pool),
• The region in which the swimming pool is located,
• The average temperature desired by bathers,
• The period of use of the swimming pool,
• The location of the heat pump in relation to the pool (the length of piping required between the heat pump and the pool affects the filtration flow rate).

The heat pump model

Taking into account the characteristics of your swimming pool, you will then need to choose a heat pump model, taking care to check the following points:

• The filtration flow rate, which must be sufficient to pump the water from the pool to the heat pump and then from the heat pump to the pool while ensuring water filtration.
• The COP (Coefficient of Performance) which expresses the number of calories returned by the device for one calorie consumed. As a general rule, the COP of a heat pump is between 3 and 5. The higher the COP, the more efficient the device.
Example: a COP of 5 means that the heat pump restores 5 kW of energy for 1 kW of electricity consumed.
• The minimum air temperature required for the heat pump to operate. A detail that is important for colder regions.
• The noise emitted in decibels at a certain distance from the device. It is important to carefully assess the location where the device will be installed: distance / swimming pool and distance / house or neighborhood.
• The presence of a defrosting function or operation in all seasons are also criteria which may be important depending on the location of the pool.

As you will have understood, to choose the heat pump adapted to your swimming pool and your wishes, it is preferable to call on a professional who will suggest the product which will be best suited to your swimming pool.
