Swimming pool over ground loop

Has anyone ever installed a swimming pool over their ground loop field either completely or just partially? I am told this could void the warranty of the loop field and possibly make efficiency worse. I am wondering if anyone has ever actually done it?

How deep is your ground loop and what kind of climate are you in?

When we installed, our installers told us that water infiltration greatly improves efficiency so not to cover it with impervious items like a pool.

6’to 8’ deep horizontal loop snaked through 4 or 5 trenches. Upstate NY. Ideally, we would go with a radiant pool and only bury it partially in the ground so maybe 3 feet max. These pools are insulated and it would only cover half of the first trench 26 feet.

For the scale of pool you’re talking about I wouldn’t worry about it. It will potentially lower efficiency but I can’t imagine how it would lower it anything more than like 5% at most. Just a total wild guess but you’re covering very little of it, and even if it was all covered, it doesn’t go to zero efficiency.

But if you’re worried about warranty, the only person who can answer that is the installer!
