insulate floor on AG 27ft radiant pool?

[ylesew]

Brand new to FTP. Really loves the wealth of info. I'm hoping someone can give me some guidance:
I live in northern Wisconsin where's it's cold. I'm putting up a 27ft radiant pool and I' 've had a lot of people tell me to insulate the bottom. i know that the majority of heat loss iis at the pool surface. But with mother earth always at approx 54 degrees, i also believe that there is heat loss stolen from the bottom. A couple questions i have:

1. insulate floor - Yes or no?
2. Will weight of water crush insulation?
3. If yes, what type of insulation?
4. If yes , how would you connect insulation board to each other (duct tape, etc?)
5. If yes, would you put the insulation above or below a couple inches


I appreciate anyone's opinion. Would love to hear success stories and/or see pictures.

Thanks again,

Dave

Welcome to TFP!

Someone with good ABG pool knowledge will be by soon to get your question answered.

We didn't insulate the bottom of ours but did have the sides insulated and I think it made a difference with losing heat as well as using the solar cover whenever the pool was vacant and at night.

Lot's of people use pink insulation board, the regular stuff you but at a big box. I personally don't believe it retains any meaningful level of heat and I don't think that should be the prime reason to use it.
The main thing it achieves is a nice flat surface without wrinkles or humps.

As for wall foam, sorry if I sound difficult but it simply dosn't have the r value to make a difference in heat retention.

Just my 2 cents.
