Pool dehumidifier

When installing an indoor swimming pool, it is crucial to understand that warm water evaporates, progressively saturating the air with humidity. This situation can quickly create a suffocating atmosphere and lead to degradation of the installation and the room housing the pool, especially if you install a pool heating system, the room's humidity can become a major problem. It is therefore imperative to plan for a dehumidifier in any indoor pool project.

How to choose a swimming pool dehumidifier?

The choice of dehumidifier type for an indoor pool is based on several essential criteria. First, consider the size of the pool and the water temperature, as these elements directly influence the evaporation rate. The larger the pool surface and the warmer the water, the greater the humidity generated.

The ideal humidity level in a room containing a swimming pool is between 60% and 70%. If this rate exceeds 70%, condensation can damage the building's structure, while air that is too dry can become uncomfortable.

There are three main types of pool dehumidifiers. The wall-mounted pool dehumidifier is the most common. It is fixed to a wall and operates autonomously to absorb ambient humidity. The built-in dehumidifier is ideal for discreet integration, as it can be placed behind a wall or in a technical room. Finally, the ducted pool dehumidifier is a high-end solution that allows air treatment via a duct network, ensuring maximum comfort with uniform distribution of dry air.

Another criterion to consider is the power and efficiency of the device. This is measured in liters of water extracted per day. A dehumidifier that is too weak will not be able to maintain a stable humidity level, while an overly powerful model will consume more energy than necessary. It is advisable to choose a device adapted to the room's air volume and the average water temperature.

What are the advantages of a dehumidifier?

Using a dehumidifier offers several advantages for an indoor pool. The first is the protection of walls, ceilings, and surrounding installations. Excessive humidity causes mold formation, paint peeling, and material degradation. With a good dehumidifier, the ambient air remains dry and surfaces are protected against humidity.

The second advantage is user comfort. A room that is too humid quickly becomes uncomfortable, making the air difficult to breathe and promoting a feeling of dampness. By maintaining an optimal humidity level, a dehumidifier significantly improves the atmosphere and the well-being of swimmers.

Another benefit is reduced heating costs. Air that is too humid is more difficult to heat, which increases energy expenses. By eliminating excess humidity, the dehumidifier helps maintain a stable temperature without excessive economic consumption.

Finally, this product helps preserve the pool's technical equipment. Excessive humidity can damage pumps, filters, and electrical systems, leading to breakdowns and costly repairs. By regulating humidity, the dehumidifier extends the lifespan of these equipments.

How to install a pool dehumidifier?

The installation of a dehumidifier depends on the chosen model. For a simple wall-mounted dehumidifier, the easiest to install, it simply needs to be fixed to a wall near the pool, ensuring sufficient height for good air circulation. It must be connected to an electrical supply and a drainage system for condensed water.

Built-in models require a technical space adjacent to the pool. They are designed to be installed behind a partition, with ventilation grilles allowing air exchange between the room and the device. Installation must be done carefully to avoid any obstruction of air flows.

Ducted dehumidifiers require a more complex installation, with a network of ducts connecting the device to different areas of the room. This type of installation is generally carried out during pool construction or a major renovation, as it requires integration work.

Regardless of the model, it is essential to choose a strategic location to ensure efficient air circulation and avoid areas of humidity stagnation. A professional can help size the installation and position the device optimally.

What size dehumidifier to choose?

The required dehumidification power is determined by the volume of air to be treated and the humidity level generated by the pool. A device that is too small will be ineffective, while an overly large model will unnecessarily consume energy.

To choose the right dehumidification capacity, you need to consider the pool surface area, the water temperature, and the ambient air temperature. Generally, a dehumidifier should be able to extract between 50 and 100 liters of water per day for a medium-sized pool. For a large pool, it may be necessary to opt for a model that can absorb more than 200 liters per day.

The airflow rate of the dehumidifier is also an important criterion. It must be sufficient to renew the air several times per hour to prevent condensation from forming, regardless of your pool type. A flow rate of 500 to 1500 m³/h is generally recommended for an indoor pool, whether it is an above-ground pool or even an enclosed pool.

What is the price of a pool dehumidifier?

The price of a pool dehumidifier depends on several factors, including power, type of appliance, and available features of the equipment.

Wall-mounted dehumidifiers cost between 2500 and 3500 euros. They are suitable for small pools/spas and medium-sized private pools (up to 60 square meters).

Built-in models, which are more discreet and efficient, range in price from 3000 to 7000 euros depending on their air treatment capacity.

Ducted dehumidifiers, which offer the best comfort and optimal humidity management, are the most expensive to purchase. Expect a budget ranging from 7000 to 15,000 euros, installation included.

In addition, there are operating costs, mainly related to electricity consumption. However, a properly sized dehumidifier helps limit these expenses by reducing heating needs.

How does a pool dehumidifier work?

A pool dehumidifier works on the principle of condensation recovery. Humid air is drawn into the device, cooled so that water condenses, then reheated before being redistributed into the room. The condensed water is then drained away.

Some models use an integrated heat pump (HP) to recover energy from humid air and heat the pool water, which saves energy.

The most efficient devices are equipped with sensors that automatically adjust the power based on the measured humidity level, ensuring optimal operation in all circumstances.

What problems does a pool dehumidifier solve?

Dehumidifying your room solves several problems and avoids certain risks associated with excessive humidity. It prevents condensation on windows and walls, thus avoiding water marks and surface deterioration. It prevents the development of mold and fungi, which can harm the building's structure as well as the occupants' health and cause discomfort with unpleasant odors.

It protects the equipment and materials in your indoor environment by preventing corrosion of metal parts and swelling of wooden elements. It also reduces energy consumption by maintaining a stable temperature and limiting heating needs.

Finally, it ensures healthy and pleasant air, avoiding a suffocating sensation and allowing users to fully enjoy the atmosphere and their indoor pool without discomfort.
