Heat Pump Water Heater
I’m planning a complete renovation and a second floor addition for my electric only house. The house is located in Westwood, MA, I believe it is zone 5. Currently the house is on a single 50 gallon electric water heater. We are family of 6, 4 adult and 2 kids, so I want to go with a minimum of 80 gallon heat pump water heater. Here’s the question, since the 50 gallon version qualify for $600 in rebate and the 80 gallon only have $150 in rebate, I was thinking to go with 2 50 gallon instead of a single 80. With 2 50s it will cost less in equipment and more hot water capacity then a single 80. Can 2 of the HP water heater install in the same mechanical room in the basement? Or should I separate them and put one in the attached garage. If I put them in the basement mechanical room, should I insulate the room or not? Thanks in advance.
