With the standards held by the wellness industry continually being escalated, spas and health facilities need to be doing more than ever to keep up with increasing expectations from their visitors. While calming interiors, relaxing scents and soothing music all enhance the experience, any ambience they create can become meaningless when moisture in the atmosphere is left unregulated.
In this article, we cover everything you need to know about humidity in indoor spa and wellness pools and why choosing the right dehumidifier is vital for maintaining your building and maximising your guests’ experiences.
Why is controlling humidity so important?
Unregulated humidity will affect two of the most important aspects of an indoor spa and wellness swimming pool:
- Maintaining a clean and luxurious space
Many litres of water can evaporate from the surface of your swimming pool in a single day. In a poorly ventilated environment, this moisture will remain in the air until it settles as condensation on any surface that’s colder than the current air temperature (usually windows, doors and metal fixtures). This will quickly lead to rust, mould and mildew that will gradually eat its way through the structure of your building.
Chlorine that’s captured in the atmosphere will exasperate this issue, aggressively corroding almost any material it comes into contact with. As moisture finds its way into other parts of your building, it can damage carpets, rot wooden furniture and, if it condenses on light fittings, cause electrical malfunctions.
- Providing a safe and welcoming experience
As well as causing expensive damage to your building and equipment, mould and mildew that forms as a result of condensation is not only unhygienic, but a serious health risk. As it spreads, mould releases toxic spores into the atmosphere that can lead to skin irritation, severe coughs and respiratory issues.
Even if mould can be kept at bay, high humidity levels make it difficult to maintain a comfortable temperature, creates a foggy atmosphere and can lead to slip hazards if condensation forms on tiles. Not exactly the relaxing environment your guests were hoping for.
For the sake of your visitors and your building, a long-term, preventative solution must be put in place. Getting this right will save you the time, hassle and costs that come with unregulated humidity levels.
While adjusting the temperature and increasing ventilation will alter relative humidity (RH) levels, this alone is not enough to prevent the risks posed by water damage. In fact, it can often make things worse. A dehumidifier, on the other hand, will circulate humid air around your pool hall and physically remove the moisture as it flows through the system.
For smaller swimming pools with less activity, such as spa and wellness pools, we would usually recommend a condensation dehumidifier as the most efficient and cost-effective solution.
How a condensation dehumidifier works
Damp air is drawn into the dehumidifier and across a refrigerated coil
The air is cooled below its dew point, condensing the water vapour
Latent heat energy is recovered and re-used
Cooled air passes across the condenser and reheated
The warm dry air is then returned to the room at the required humidity
Key benefits of condensation dehumidifiers:
High performance level, even in unheated rooms
Powerful centrifugal fan
Professional hot gas automatic defrost
Automatic hygrostat controlled dehumidification
Can connect to an external condensation drain or condensate pump
How to choose the best condensation dehumidifier for your indoor swimming pool
Because every indoor pool is different, there are lots of things to consider before you can determine the most appropriate dehumidification system, including:
Typical indoor and outdoor temperature (summer and winter)
Typical indoor and outdoor humidity (summer and winter)
Type of pool
Pool hall/room volume
