The home I built in 1997 was on-grade concrete slab with in-floor heat and great insulation. Very efficient and comfortable. We had changed to a comercial GSHP suplimented with solar hot water to heat the floor. Now the cost to stay warm in Canada is easier to live with. Next I will try to build my own GSHP for my shop 1600sqft. I will be converting a 2.5T air cond. and direction from your thread. Half the shop already has in-floor But the balance of the concrete will have to be torn out and installed with PEX.
I have found with the solar hot water suplimental that a heat exchanger (HX)/copper coil built inside a hot water tank is not as effective as a counter flow brazed plate HX. After all the heat transfered to the water in the tank is by gravity off the copper coil.

Looking forward to hacking the AC
