Indeed dehumidification can be expensive; it uses a lot of energy. What you're imagining is frequently done in low humidity areas, but it does not work in most climates because the humidity differential is too much to manage a consistent RH level. Everything needs to be maintained in equilibrium, and outside air varies too much for that to be the only solution. The good news is, good pool dehumidifiers can sense the humidity of the outside air and they adjust accordingly, so when the humidity outside is low, these systems take that into account and energy is saved.

You're correct. The pool room (natatorium) should be ~10% negative relative to adjacent spaces (bathrooms/lockerrooms, lobby, hallways, etc.). This requires selecting the right type of doors and windows to seal air properly, and having a pool dehumidifier that controls the pressure in the space. The pool dehumidifier (PDU) controls the negative pressure in the space by regulating how much exhaust air and outside air move through the space. I hope this helps!

Yes, Steve's smoke alarm was beeping. And unfortunately we couldn't edit it out because it was always when he was speaking...

Hi Mark. Yes. Email us at [email protected] and we can put you in touch with someone.

An acre could be enough, but you'd need to factor in deck space, equipment, access, etc. It would be safer to have more like 1.5 or 2 acres.

Official Olympic pools are 2 meters deep. As for more pictures, video editing is not our forte. Clearly.

Thin water is a good answer, we like that. We'll go with that.

From Keith: "An air recuperator is also known as a push-pull air handler with energy recovery. This system will only solve the humidity issue when the outside air conditions are lower than the design conditions and therefore is rarely used. There are only a few year round climates in the USA that this will work. Many hours the humidity and temperature outside is higher than inside the pool room and cannot provide conditioning. The other issue is that even with energy recovery, this system will actually have higher energy costs because dehumidifiers have two internal energy recovery elements (for the air and the pool water) that are significantly more efficient than an air to air recuperator. The use of low exhaust on larger active pool rooms has been very successful in mitigating the off gassing of the chemicals. In residential or small hotel pools, insuring the system is introducing code ventilation is sufficient." Hope this helps!

Glad you enjoyed it!

Glad it was helpful. Thanks for watching!

Great to hear. 1948?? It's rare to see natatoriums that old...very cool. Let us know if you need further help with the project. I'm sure we can learn a lot too. [email protected].

Glad it was helpful!
