Hi all, new here and looking for some perspective.
I am thinking of a digging in a microbore copper ground loop (under the shed I am building) which is fed directly from the compressor (so no heat exchanger or pump) and powered by solar from the shed roof area. The idea is to create a GSHP to bring the temp down during summer when there is lots of solar generating opportunity. The shed will be insulated with 50mm PIR in the walls and 100mm in the floor and ceiling. I have never done anything with heat pumps or HVAC before so I would be making it up as I go along and it will be spectacularly DIY and not at all cost effective. But its interesting and I think GHSPs are cool, I would consider even a couple of degrees of heat reduction as a success.
I do have a 16A feed to the garden so can use that if solar is not sufficient. The floor area is 4m x 2m and I estimate the copper loop will be ~50m.
The only reason I am asking and not experimenting is that I just had this idea but am due to finish the shed base soon and need to decide if I should at least put the copper whilst I can.
So - could this work?
