What challenge? Any of the HPWH brands can duct exhaust out of the home. Try Sanden if you want more than that.

- kennywinker 4y agoThe all-in-one heat pump hot water heater pulls in warm air from its surroundings, pulls the heat out of it and puts that into its water. Then it lets out its "exhaust" colder air. Ducting to outdoors improves things, because it doesn't put that cold air back into your basement / utility closet, but you're still pulling heat out of the air - which your house heater now has to put back into the air - and unless your space is perfectly airtight, that's probably just going to be sucked in via the nearest air gap to outside. It's a bad system. Split systems make sense, and I know they exist, but they seem weirdly rare.

- 1123581321 4y agoThe ducting brings the temperature drop to an almost unnoticeable delta. If you are worried, just install it near your furnace. It’ll eat radiant heat from that corner that would otherwise go into the walls, egress windows etc. Every other part of the year, you either don’t mind or benefit from the cooling. I have the stats from my own Rheem to know I’m coming out ahead financially during winter and also haven’t seen a meaningful swing in the basement climate. I’m a regular participant in that linked blog, too. :)
