heat pump water heater retro fit version

Hi Westend,

Have you been drinking ever clear again? (naughty naughty)

Maybe they have a section on RV use.

Yeah, well, I'm not so "elderly" that I can't tell if I'm being scalded, and I'm pretty sure no children are living here.

My gas HW is way hotter than 130. Isn't yours?

The problem with an RV is where does the heat pump scavenge the warm air to heat the water heater? It may be that you are lowering that hard-fought interior temp of the cabin to heat the water. There would definitely be connection issues with this device in an RV, as well.

Heat pumps and residential 40+ gallon tanks are a pretty good fit, especially if the heater is electric. If an owner has Natural Gas water heating and a damp basement, it can also work well as the heat pump acts as a dehumidifier, too. Payback on electric residential water heaters can be as short as 3-5 yrs. Gas water heaters will have a much longer payback on the heat pump. Coupling a heat pump with whole house geothermal to serve both forced air and water heating makes a whole lot more sense and most Mfg's of geothermal solutions are rolling out the auxiliary use for heating water.

These are very expensive and I don't see the savings. A few years ago GE came out with them was on the band wagon for us and other authorized servicers to sign up for servicing these I declined. At that time if I remember cost of one was approaching 3000.00

Maximum Temperature

Setting too high can scald someone using the water. This is particularly easy because when you first open the tap, the water in the pipes has cooled down some, and so its temperature will raise (possibly dramatically) once the water from the tank reaches the point of use.

Not sure I understand the novelty here. Max temp 130° wouldn't please me.
