Heat pump hot water heater tank size
Family of 4, 2.5 baths, dishwasher and washing machine in our house. We have a 20+ year old RUUD electric hot water heater w/ a 50 gallon tank.
We are most likely going to upgrade to a heat pump hot water heater – we live in Virgina, have an unconditioned basement that could use dehumidification, and have no gas connected to our house.
My question is what size HW heater to get. My initial thought was just another 50 gallon one, because our current HW heater has seemed sufficient. But then I read this:
“All of the researchers I talked to emphasized the benefits of a large tank size, so don’t buy the G.E. unit, the Rheem unit, or the smaller AirGenerate unit. “Bigger and hotter tanks are better,” said Aldrich. “It’s counterintuitive.” – https://www.greenbuildingadvisor.com/blogs/dept/musings/heat-pump-water-heaters-come-age?page=1
The 80 gallon AO Smith and Steibel Eltron models are at least $1000 more than the 50 gallon GE model. How important is it to upsize? – that’s a huge price difference. Anyone with a similar set up to mine using a 50 gallon hybrid successfully or having buyers remorse?
