Have picked my furnace, arrives (I hope) in 4 weeks or so.... (Portage and Main 250 gasser), trying to plumb up things before it arrives and pour pad etc.... question on plumbing.... I was all set to locate the water to air heat exchanger just above the "A" coils on two existing furnaces... both identical.... except one has a box leaving up and other has round tube.
A guy I was just talking to who just installed an outside water furnace with a central heat and air existing system told me his installer told him they needed to (and did) install the hot water heated water to air heat exchanger IN the return side, right next to his furnace because if located IN the exiting air flow, it would hinder and upset his Air Conditioning output in the summer more in that location.
Which is best, supply or return air side and if it's in the return wouldn't that overheat after exposure the motor spinning the fan, and if in the supply side restrict the Air Conditioner flow and maybe sweat being right in the coldest air hitting it right out of the "A coil" output flow in the summer?? Any thoughts would be appriciated. Eastern Tennessee....
