Small indoor heated therapy pool

[Deb Driesen]

I've ordered a fiberglass therapy pool 8'x12'x4'6" to be indoors. Is UV light purification worthwhile and is a SWCG the way to go or just chlorine? Thanks in advance,
Deb

Welcome to the forum!
For an indoor pool, a UV system is a good idea. Also a SWCG would be great way to generate your chlorine. Your daily needs will be less than an outdoor pool.

How are you set up for ventilation in that room? That is going to be an important element lest the extra moisture cause mold.

Such a small pool might be able to use a Saltron Mini Salt Water Chlorine Generator for Spas I bet? Do you know how many gallons the therapy pool will be?

Yes we really want to keep a constant temp/humidity in the room to avoid evaporation and condensation on interior surfaces. We are planning on an in wall HVAC plus a bathroom style ventilation on the opposite wall. There will be windows to open during good weather.
I think the volume of this pool is approximately 2500 gallons.
Thanks for your help,
Deb

Most indoor pools have extensive air turnover and use crossover air circulation units. Cold weather isnt bad the added moisture helps on forced air units, but the summer needs dehumidification

I second the Saltron mini, should work perfect for your size..

Ok, so after much reading I'm firm on buying a swcg and UV light for our new fiberglass pool that arrives end of April. It will be an indoor pool, inside a sunroom. The UV light is being provided by the SwimEx pool manufacturer, along with pump/cartridge filter combo and 11kw electric heater. The pool is a small plunge pool, flat bottom, for physical therapy, size is 8'x12'x4'6" deep with built in steps and a pair of custom railings. This calculates to be 3450 gallons. So far I have looked at the Saltron Mini swcg but it appears to be best suited for 2000 gallons. Most others I've seen are indicated for pools up to 10,000 gallons. My question is, if we get a swcg designed for up to 10,000 gallons and our pool is 3450 gallons will we generate too much chlorine or not convert sufficient salt? Are there any other swcg we should consider? SWCG is a higher initial expense, I understand so we want to get it right. Therapy is very important for me so once we get this up and running I'm hoping to keep it running with no down time. Thanks in advance for your help, advice and support!

Hi everyone,
We are installing a new 20'x16' sunroom and including a plunge pool for physical therapy twice per day. The pool will measure 8'x12'x4'6" deep and will be covered when not in use. We plan to put in a 24,000 btu mini split HVAC unit and there will be a ceiling fan to help move the air. I read that a bathroom vent fan is also helpful in removing heat and humidity. So I'd like to put one on the wall opposite the HVAC unit. Is that sufficient? I would really appreciate any info/advice on indoor pools, especially about room ventilation. Feel free to name names, brands etc., if allowed here.
This forum is a real lifesaver! Thanks in advance.

A mini split system + ceiling fan + bathroom vent fan is not a properly engineered environmental system to manage humidity in an indoor pool room. You need a properly engineered system that monitors the room humidity and exchanges air from the outside as necessary to maintain the room environment. You need to speak with an HVAC contractor who has experience with indoor pools.

Otherwise you risk mold and mildew in the room and maybe in your house depending on the way the pool room is connected with the rest of the house.

This sounds like a neat project. Also doing a pool for indoor aqua jogging for fitness and swimming. Have thought about this for the past years. We finally settled on a 12 x24 5’6” small pool with a Swg, 250,000 BTU gas heater, auto cover in a Garden prairie enclosure by CCSI. It will be separate from the house as we had concerns about humidity. Looking forward to seeing your updates and will share mine—our project is in the permitting phase.

The Saltron mini is too small for your 3450 gallons.

Look at getting a Hayward Aquarite with a T-3 cell.

Usually we recommend you get a SWG that has the capacity for 2X your pool volume. But with an indoor pool you don't lose chlorine to the suns UV but your UV system can consume some.

You manage the chlorine output by a combination of the % generation output setting on the SWG and the pump runtime. You will run the SWG at a low % and likely run your pump for only a few hours a day.

Hi all,
I'm looking at the

Autopilot Pool Pilot Eco Nano Salt Chlorine Generator for my 8x12 therapy pool. Does anyone have experience with this particular swcg?​

 

[cowboycasey]

Compared to a Circupool SJ 35 it is more expensive, makes less chlorine, has 3 years less warranty and the replacement cell also costs more.......

I have had my SJ45 for 7 years and just replaced the cell.. I love it and it just works...

And you can get the SJ35 for the price of the SJ20 right now

Thanks, that's very helpful!

Hi all, it's a learning process, for sure.
For our 16x20' sunroom which will have a 12x8' therapy plunge pool we are looking for an air handling system that will prevent condensation and mold. Is anyone who owns an indoor pool familiar with DXair / Veri-Dry LLC ?

 

[kimkats]

Here is a current link to a wonderful indoor pool. I don't know what system they use but it should be helpful to get your started:

Most construction complete :)

I remodeled my natatorium starting on 12/12/20. It's been a long and costly road so I thought I would share some pics.

Hi folks,
What is best for HVAC in a sunroom with plunge pool? Room is 320 sq ft. Pool surface area 96 sq ft and will be covered 22 hours out of every 24. I've talked with builder, engineers, plumbers, hvac guys, searched online. Everyone has a different idea. I want to know who has an indoor pool and what do you use for HVAC air handling. How do you move air and ventilate the pool room. Our pool manufacturer says we need to replace all the air in the room three times per hour to prevent condensation. Even if we keep room temp 2° above pool temp. I need solid advice please. I'm allergic to mold. Thanks in advance. I'm so grateful this group exists.

How are you set up for ventilation in that room? That is going to be an important element lest the extra moisture cause mold.

Its 3240 gallons.

Any thoughts on ventilation would help. Room 320 sq ft. Pool 96 sq ft will be covered 22 hours out of 24. Pool mfg says we need to exhaust the room air three times per hour to prevent condensation and mold. They also said a room dehumidifier could be added if needed.

Deb, post back as much as you need to for replies to your question. Indoor pool owners are here, but it's hit & miss catching their attention. For what it's worth, we got a Mitsubishi mini-split unit for our game room a couple years ago. Not the same scenario I know, but it was a nice install and works very well in our application.
