Has anyone used something like this: http://www.thermastor.com/heat-recovery-water-heaters/ ? Or the Mueller Fre-heater system http://uk.paulmueller.com/products/mueller-fre-heater ?
We were sold something similar years ago. It didn't produce significant warm water, and eventually failed (leaked between refrigerant circuit and water circuit), costing us a refrigeration compressor and $k to get the refrigeration oils out of our HL system. New boss wants to try again.
Admittedly, this system looks much better (on paper) than the POS we were sold--which turned out to just be a water-cooled condenser unit from a standard walk-in cooler, encased in an SS box.
