I got a HPHWH and I think I regret it. I wish I would have gotten the unit that combines with the standard HP, moving the compressor and the cold it brings (in winter) to the roof rather than right next to the master bedroom. But we didn’t want to add cost and complexity to the whole thing.

That in my mind is the biggest drawback of HPWH when it can't be installed out of the way in e.g. the basement. Plus, you now probably have higher heating needs as you need to bring more heat into the house to supply it to the HPHW... Thanks for sharing!

Thanks for sharing your experience with HPHW. I’m curious if you considered one of the 120V models from Rheem or A O Smith. The manufacturers recommend upsizing the tank size, but you’d avoid the cost of running 220V service to the unit.

BTW, I haven’t personally replaced ours (tankless gas), mostly because I haven’t walked into a flooded utility room, but have had several contractors quote outrageous fees to get the ball rolling for an eventual replacement.

I did, but only for a minute. My panel has plenty of space, and I already have other 200V lines running through the house. Plus not having to upsize the tank saves on cost. I think the 120V units are most useful when the panel can't support the new load, and an upgrade isn't feasible.
