Why choose an exchanger to heat pool water?

A heat exchanger for the swimming pool: under what conditions?

Does the heat exchanger heat the water in all types of swimming pools? What are its strengths? How is it effective? What are its limits?

The heat exchanger for swimming pools is connected to the heating of the dwelling. The efficiency and energy cost of this heating method for swimming pools are directly linked to the performance of the central heating. The heat gain for the pool water and the financial cost depend on the good efficiency of the main installation, its performance and the fuel used: gas, oil, solar, heat pump, geothermal energy... II must, however, check its compatibility with an all-electric heating mode and it may be incompatible with wood heating.

The heat exchanger, for which pool?

The heat exchanger can be installed for indoor or outdoor swimming pools, regardless of the volume of water, if the pool is equipped with a technical room or a filtration unit. In addition, it adapts to all treatments including salt electrolysis treatment.

The heat exchanger is ideal for a second home. Its rise in temperature is all the more rapid as the installation of the domestic heating of the dwelling is efficient.

The advantages and disadvantages of the pool heat exchanger

The advantages of the heat exchanger

The heat exchanger is a method of heating for swimming pools recognized for its reliability and robustness. As this device is compact, it is particularly suitable for a cramped technical room. It is easy to install and it is simple to use.

The temperature rise is quite fast, it takes between 24 and 48 hours to reach a comfortable bathing water temperature, it all depends on the performance of the heater central and the initial temperature of the water.

Finally, its price for conventional pools is more around 500 euros (and up to 3,000 euros for 200 m³). The cost of use depends on the type of energy of the boiler and its performance (latest generation equipment more economical than old installations).

The disadvantages of the heat exchanger

The swimming pool, technical room and boiler assembly must be within a perimeter close to each other. When they are too far apart, this generates significant heat loss.

For the expected results to be convincing, to obtain hot water quickly without breaking the bank, the boiler must be efficient and economical.

Energy consumption can quickly increase if the central heating installation is not efficient.

In some cases, the intervention of a professional (electrician or swimming pool specialist) is necessary for the installation.


Here are in a nutshell the main characteristics of the use of a heat exchanger for swimming pools.
