Controlling Moisture and Humidity in Indoor Pools

Controlling Moisture and Humidity in Indoor Pools

Dehumidifier system

Indoor swimming pools are a nice addition to any home, hotel or apartment complex. However, as relaxing as it may be to have access to a heated indoor pool, they require a delicate balance in order to prevent moisture build up from developing and damaging the surrounding area.

The high humidity which is usually present in an indoor pool environment can result in more than water running down interior windows. That moisture can destroy the building structure with rot, create health problems with mold and mildew and create an uncomfortable environment.

The aspects that affect the moisture levels inside the average indoor pool include:

1.  The Building Envelope

The ‘structure’ or ‘room’ that contains the pool is a key component. The way in which it is constructed will have a huge impact on the environment of the pool.

Construction materials, the use of a vapor barrier, windows and foundation can all play a part in the lifespan of the indoor pool.

2.  The Ventilation

As indoor pools create high humidity levels, being able to move the moist air out and away from the pool area is important. Air supply ducting and venting should operate in such a way that windows do not collect condensation. The air quality also impacts the pool users.

There are automatic humidity control solutions available that can activate air ventilation and extraction systems depending on the amount of humidity in the air. For more information on automatic humidity control systems, click here.

3.  The Dehumidification

For effective control of humidity in the air inside the indoor pool room a dehumidifier is often required. A properly functioning dehumidifier unit would be able to keep the relative humidity at a level between 50 and 60 percent. Heating and cooling of the air can also assist with this process.

The Problem With Evaporation

Think of the indoor pool and the room it is in as a large sealed box. Water that gets splashed out of the pool from swimming, horseplay and even through wave action created by swimmers can end up on the tile surface outside of the pool. In addition to this, the heat in the room causes it to evaporate.

A surprisingly large amount of water can evaporate from a large indoor swimming pool during the course of an average day. This water vapor has to go somewhere and without the proper elements in place it adds to the humidity in the sealed box. This humidity can become dangerous.

High Humidity

High humidity creates problems in any setting but when it is in an indoor swimming pool, the dangers are greater. Mold, rot and corrosion develop over time. These things will eat away at the pool structure, the building structure and create air quality issues that are bad for human health.

When chlorine is added to the mix, the resulting damage can take place even faster as chlorine is an aggressive chemical. When chlorine condensates it can eat away at any kind of building material ranging from walls and ceilings to the tile decks and even the pool itself.

With dehumidification measures in place, and functioning properly, the moisture content in the air is kept at a safe level. With correct humidity levels in an indoor pool building, it creates a safe environment for the structure and good air quality for those enjoying the pool facility.

Keep Your Indoor Pool Safe From Damage

Because indoor pools are costly to maintain and operate, it is important to keep them functioning properly. The best way to do this is to ensure that the building that houses the pool is built correctly. And you need to keep the building neat and clean, using these house cleaning tips.  The building materials should be able to withstand the higher humidity levels.

Vapor barriers must be present to protect the building structure beyond the walls. Ventilation should be in place to provide a correct and ongoing exchange of warm and cool air. The warm humid air should be removed with cooler outdoor air filtering back into the pool building.

A dehumidification system should also be included in any indoor swimming pool setting. This will control the amount of moisture present in the air reducing the risk of condensation.

Controlling the moisture levels in an indoor pool area can be tricky, but needs to be addressed to protect your property from expensive damage. By staying on top of excessive moisture in your indoor pool area, you will be able to enjoy it year-round.

Best pool cleaner legend

If you need a little expert advice and assistance, it is always a good idea to call in an expert, like “Paul the pool man”.  There is nothing quite like some expert advice about how to manage your swimming pool, and once you learn some of the professional tricks, it can make your life easier.  If you can’t get a professional to visit your pool, you can conduct your own water quality test, and take the results to your local pool shop for an expert analysis of the water quality results.


Best Pool Cleaner Myths:


Myth #1:  You need to run your pool cleaner for 6 hours every day

This is not true when your pool cleaning system is operating correctly.  Certainly if one or more of the components of your pool is not operating properly, then it may require longer filtration times, or some other remedy.  If the chemical balance not correct, or if the chlorinator is not delivering the right amount of chlorine, then the pool may not appear to be as clear and clean as normal.  However, it is best to conduct a water quality test to get to the bottom of the problem, rather than simply running the pool filter endlessly to try to keep the pool clean and clear.


Myth #2: You need to add more chlorine after heavy use

This is also not true.  Sometimes your pool may seem to suffer from periods of heavy use, but this can usually be remedied after the next filtration cycle.  The best way is to check the chemical composition before adding any additional chemicals.  If you are running a salt water pool, then perhaps the chlorinator needs a little extra run time to increase the normal chlorine level, and a little extra filtration time won’t hurt.  But if the problem persists for any undue length of time, then it is always prudent to test the water quality before taking any other drastic action.


Myth #3: You need to run your pool cleaner more often to stop it going green

Sometimes when the weather warms up, a build up of waterborne algae can threaten to over come your pool’s natural blue color and turn the whole lot green.  Although this is not overly serious, it can be a real pain to fix, and put a real dampener on any swimming activity.  In fact, I know I wouldn’t want to go for a swim in green sludge, and take particular care not to fall in accidentally when trying to fix the problem!

Doesn’t matter how long you run the filter in this situation, it won’t fix it.  The problem is an imbalance in the chlorine level, which has allowed the algae to take over, and once this happens, it is generally an out of control chain reaction.  The only way to restore the balance is to aggressively add chlorine and algicide under professional guidance, until the algae problem is fixed.  Then there are a few tricks of the trade to remove particulates from the water, and to use clarifier to get the water back to crystal clear.  Ask for help, you are not the first person to experience this embarrassing problem!  The experts can get you back up and running in no time.


Myth #4: A robotic pool cleaner is too expensive to run

This is not true.  A robotic pool cleaner does cost a little more to buy, but can actually save money in the longer term.  A robotic pool cleaner requires its own power supply and therefore it is true that it increases the energy usage a little.  But that is where the extra costs stop, and the savings start.

Because a robotic pool cleaner collects 90% of all the debris, sand and silt from the bottom of the pool, the normal pool filter will collect far less debris and therefore will not require as much cleaning or backwashing.  This is a huge saving in terms of water and chemicals that do not get wasted during the backwashing process.

Not only that, because the pool is cleaner than ever before, the normal pool pump and filter are not required to be run for as long as before.  In fact, the running time for the pool pump and filter can be reduced by more than half, which is a huge savings, and more than makes up for the extra power usage of the robotic pool cleaner.  Just consider how much you will save by extending the life of the chlorinator unit that no longer has to run for unnecessary hours each day.

A robotic pool cleaner can save pool operating costs from several angles, and the best one is that your pool will look crystal clear, and much more inviting which means there will be a lot more swimming and a lot less pool cleaning required!


Myth #5: You need a professional pool cleaner every week

Well, you certainly need to clean the pool more than once per week, but you don’t need to employ the services of a professional pool cleaner once per week.  Simply scrape off any leaves or debris that have settled into the pool, and make sure that the pool cleaner is working on a timer each day, and that is enough!  Buy the best leaf blower that you can afford and keep all the fallen leaves well away from the edge of the pool.  A regular clean up with a leaf blower – vacuum will stop the fallen leaves from blowing back into the pool area and reduce the amount of debris that gets into the pool.  Better still, it is also recommended that you buy the best pressure washer and jet blast the pavers and pool surrounds for that extra special clean.


Myth #6: You need to test the chemical water quality every week

This is not necessarily true.  Sure, if you have had problems getting the right chemical balance in your pool, and in particular to get the pH balance just right, then you would need to test the water quality regularly, to make sure it has stabilized.  But once you get more confidence with the operation of your pool, and once the pool filtration timing is sorted out, then you shouldn’t need to over test the water quality.  Unless something goes wrong!

The classic problems are the pH balance, which can have you adding acid to the pool water at intervals to try to keep everything in order.  The other important factor is the chlorine level, which can be a bit tricky.  Too much chlorine and everyone complains about sore eyes and strong chlorine smell after being in the pool.  The other end of the spectrum can be when there is not enough chlorine in the water, and there is a risk of growing an algae farm.  Always check that the chlorinator is working efficiently, and maybe increase the running time of the pool pump to allow for a little extra chlorine if necessary.
