silence7Heat-pump water heaters are a winner for the climate — and your wallet
Yes, but water heater tanks are by themselves inefficient as it stores heated water regardless of it being used.
If I ever get a house (millennial lol) I’d want to have a tankless water heater. That way supply meets demand exactly.

Tankless is crazy LESS energy efficient than a tank heat pump water heater. Why? In tankless you’re having to CREATE THE HEAT. With heat pump tank you don’t. You’re citing the inefficiency of storing a tank of hot water, but the insulation on a decent (not garbage) hot water heater is really really good! The heat loss through the insulation is VERY small. You could turn off the water heater entirely and come back days or possibly weeks later and the water is still hot.
You still have to create the heat for a water tank, too …
Not if it’s using a heat pump
LantechIn my case, the heat pump is in the basement. So in the summer it's great. It dehumidifies and cools the basement. However in the winter, it's cooling the basement too. So the gas furnace kicks on to heat the basement back up. There's a push-pull there.
However, I have solar, and an excess of electricity credits from it.
So what I've done is put it in high-demand mode which uses more electricity and less heat pump, reducing the push-pull issue.
In the summer I'll put it back in pure heat pump mode.
