This is a larger geo-radiant system with an HRV unit that we are a few days in to installing.
Inside the mechanical room, we have built an angle iron frame for stacking the heat pumps. The plumbing to the left is the outside loop being tied in to a non-pressurized flow centre. Eventually a Wilo Stratus pump ECM pump will be circulating the fluids from the surface water loop to the heat pumps.
Keeping the radiant system plumbing nice and tidy.
