My wife manages a motel and one of their problems is they have a vending area which they walled in because it was noisy. There are two ice machines , a Pepsi machine, 2 washers, two dryers, and a candy machine. As you can imagine they solved their sound problem but created a heat issue. They added a large window air conditioner. what is the best way to recover this room heat. put desupers on the two ice machines and maybe Pepsi machine or add a heat pump hot water heater in the room?
