When to use the dehumidifier for swimming pools?

Dehumidifiers for spas, for indoor or covered swimming pools, aim to control and regulate the humidity level of the aquatic room so as to avoid any damage to the building and obtain optimum comfort conditions for bathers. If the first step is to successfully install your swimming pool dehumidifier, you also need to know when and how to use it properly.

When to operate the swimming pool dehumidifier?

The use of the dehumidifier is necessary when the humidity level is too high in the spa room or the swimming pool hall. For aquatic rooms, the humidity level must be between 60 and 70% maximum.

Automatic operation of the swimming pool dehumidifier

Most swimming pool dehumidifiers are equipped with a hydrometer which automatically measures the humidity contained in the ambient air. The humidistat acts independently by stopping the operation of the device when the set value of the recorded humidity level is reached. The dehumidifier turns on automatically when the humidity level is above the level programmed on the device.

When the device is turned on, it operates continuously until until the programmed set point is reached. This cycle brings the humidity level down to the set value and lasts more or less long depending on the volume of the room and the power of the device. Subsequently, if the dehumidifier is equipped with a hygrostat and a hygrometer, it maintains the humidity level in the room with complete autonomy and independence at a lower power level.

If the hygrometer is not integrated into the dehumidifier, you will then have to install one in the aquatic room and adjust the device's hygrostat yourself to obtain an acceptable humidity level.

Can the dehumidifier be operated in all circumstances?

There is no question of operating the swimming pool dehumidifier outside its minimum and maximum operating ranges. It is counterproductive to operate the device when the temperature is 2°C, while the performance of the device begins at a temperature of 7°C. This is the reason why the lowest temperature in the region is indicated and taken into account during the heat balance. This information is important and useful when choosing equipment.

Limit the operating time of the swimming pool dehumidifier

To limit the operating time of the dehumidifier, when the weather permits, and therefore more particularly in summer, it is possible to manually ventilate the pool area. All you have to do is open the bay windows, windows or doors, slide the shelter doors or open the removable panels to renew the air and evacuate the condensation. During the ventilation period, the dehumidifier is of course closed.

Swimming pool under cover and dehumidifier

The dehumidifier when installed in a swimming pool shelter is only partially effective. In fact, the walls are not insulated and cannot be. In this case, it often operates at low speed to maintain the humidity level, for long periods without stopping, especially during the shoulder seasons, in spring and autumn. It is rare that you can swim in the swimming pool under cover in winter. Additional equipment most often allows you to extend the swimming period.



The dehumidifier is essential when the swimming pool is in an enclosed space, whether indoors, in a veranda or under a shelter. It is a simple to use device that most of the time works completely independently. The majority of them will manage their operations themselves. There is therefore no question of knowing when the device should work!



If preparing the installation of the swimming pool dehumidifier and successfully installing it is essential to optimize its performance, it is also interesting to know how to install the swimming pool dehumidifier. Indeed, this will help you understand how the device works and better understand how to maintain the swimming pool dehumidifier correctly.
