The elements to take into account when choosing your heat pump

How to choose the swimming pool heat pump?

How to choose your swimming pool heat pump so that the heat pump is fully efficient? Its operating characteristics must match the climate of the region and the environment in which it will be installed; without forgetting that it must also meet the conditions of use desired by swimming pool owners.

Choose a heat pump according to the characteristics of the swimming pool

First and foremost, it is the match between the heat pump and the characteristics of the swimming pool that takes precedence. The heat pump must be adapted to the volume of water in the pool and its flow rate must be large enough to stir and above all quickly heat the water in the pool.

The power of the heat pump is chosen according to the type of swimming pool: buried, above ground (less protected from the cold), overflow, whether it is indoors, outdoors or under cover… If the heat pump is far from the pool or the technical room, it must be oversized, because during transport in the pipes, the water will lose calories.

Due to the corrosive properties of acid-prone water, salt electrolysis treatment or sudden and unexplained variations in the water, you must choose a heat pump equipped with a titanium exchanger. A stainless steel exchanger is indicated for all other treatments and water with a neutral pH.

Choosing a heat pump according to the climate

The climatic conditions of the region also have an influence on the choice of heat pump for swimming pools: wind, frost, seasonal temperatures...

You will have to choose a reversible heat pump if the swimming pool is under a very hot climate, because bathing in water whose heat flirts with 30°C is neither pleasant nor refreshing. In addition, water that has a temperature of 28°C (and more) for several days makes most treatments ineffective or largely deficient. It is at this stage that problems with maintaining the water balance arise. It becomes almost impossible to stabilize the pH and algae grow rapidly.

Choose a heat pump according to its use

If the pool is indoors or if the wish is simply to extend the swimming period, it is unnecessary for the heat pump's operating range to be in negative temperatures.

If, on the contrary, the goal is to enjoy the outdoor swimming pool all year round, the heat pump will have to be able to operate even at negative temperatures. There are heat pumps for swimming pools which heat the water when the ambient air is at -5°C or -15°C. You must therefore take into account the operating range if you want to enjoy pleasant swimming even in the middle of winter!

It is wise to choose a heat pump model that has automatic defrosting, especially if the swimming pool is used all year round, whether it is indoors or under cover. For use only in the summer season, this function is not necessarily useful.

Choose a heat pump according to the pool space and environment

If there is little space to install a heat pump, or if the cold air blowing into the legs is bothersome, choosing a vertical heat pump is the solution.
If the noise from the heat pump causes inconvenience for the inhabitants or for the neighborhood, it is rather necessary to choose a vertical heat pump because the acoustic power is often less important than the horizontal heat pumps. However, it is more expensive and seems more massive than a "classic" heat pump. It is also more sensitive to pollution from above, leaves, pollen... A scroll compressor is less noisy than other compressors.

All this information, and the list cited above is not exhaustive, is essential for choosing the heat pump that best meets the criteria of the swimming pool and the requirements of the owners. The most difficult thing is to be able to find the heat pump that meets the majority of needs. This is why a heat balance can save time!
