Heating water with a mini-split?
OK, so if a Daiken Atherma is too expensive, can I heat water with a regular mini-split?
I plan on buying a refrigerant-to-water heat exchanger from Aquasystems Inc. They sell heat exchangers based on the tonnage. A three-ton heat exchanger costs somewhere in the range of $250. The guy I talked to said it works but If so I wonder why no one I know has tried it.
Am I crazy? Anybody every tried this? My plan is to connect the water side of the heat exchanger to the 260-gallon non-pressurized storage tank that we will be using for the drainback solar hot water system and setting it up on a timer so that it would heat the storage tank between the hours of 2 p.m. and 8 p.m. if the tank was below 120 F. That way the heat pump would be operating at the warmest time of the day but after the sun had a chance to heat the tank.
Do I risk damaging the mini-split with this experiment?
