I was considering one of these, but the consensus was that it would be more efficient to place a desuperheater on my AC unit and hook it to a Marathon electric tank.
Yes I agree that propobly the most efficient for the dollars, it is basically the same concept but uses its own coils to extract heat from the air.
I the late 80's before I was building with SIPs ,I put a heat exchanger on every home, for some reason got away from it ten years later
