Benefits:
1. HPWHs are about four times more efficient than a conventional electric water heater so that electricity costs will be four times less than a conventional electric water heater.
2. They can be controlled from a smartphone.
3. They will dehumidify the air around them.
4. Most units have an automatic leak detector.
Drawbacks:
1. Due to the built-in heat pump, the water heater needs about 700 cubic feet of air around it. If you do not have that much room , you will need external ducting to the outdoors. The HPWH will cool the air around it by 5-10 degrees F.
2. Because of this local cooling effect, HPWH's are usually placed in an area such as a basement where this isn't a problem.
3. When operating, it is about as loud as a dishwasher.
4. Finally, the heater will produce condensation while working, and this must be drained. If there is no floor drain nearby, an additional condensate pump will need installation.
