Before backfilling around rear of my new house & retaining wall, I put down a 450’ loop of blue 1” pex.

I’m thinking about how I can use this loop to help heat or cool house.

The soil (ha) is really about 90% small decomposed granite gravel with about 10% clay.
It stays damp year round from Summer rain & Winter snow.

I think? it could support a 1/2 ton heat pump.

The emitter/collector could be the upstairs underfloor pex loops?

The climate has low RH, so reaching dew point is not likely??
