Open loop Ground source heat pump
I am building a 3000 sq ft modular home. Current plan is to install on a Poly Steel ICF Foundation with a 3″ slab in the crawlspace. The crawlspace will be conditioned. Will there be any value in running a radiant heat loop thru the crawlspace slab and routing the Ground source heat discharge thru it?

You would be cooling the slab. Not good. The temperature of the gs water is going to be less than the conditioned space .
He's in SC. The GS loop output will be warm most of the time.But either way, I don't see the sense in it. For an unconditioned crawl keeping it warm might reduce dampness, but with a conditioned crawl it would just fight the heat pump.

Kinda like using the refer for an a/c.
What everybody else said.
My groundwater discharge from WSHP during heating season is 40F water, not much of a radiant loop there!
So much for that BRILLIANT idea. Thanks for setting me straight
