Induction Water Heaters: Are They Worth It?

I did not think the kitchen range was an important consideration as the title of the thread was “Induction more efficient than resistance for a water heater?”

The OP asks specifically about the differences between ranges and water heaters that might make one work for a range and not a water heater. The opposite can be considered as well.

There is also overlap of course in that if you are using a range to boil water, you can do half of the heating with a water heater or all of the heating on the range.

But all that said, I've never seen a heat pump water heater in a residential setting and only once commercially*, so even then it isn't exactly equivalent to the others, which is why I pointed it out. One big potential downside is they need an external heat source. Heck, it is even common commercially for an a water to air heat pump to be sourced from an electric boiler!

*Er; the commercial one was hot water for heating, not drinking. Residentially, checking what I think are the top 2 manufacturers, both offer air source heat pump water heaters. In the summer they provide free air conditioning and in the winter their source is whatever you use to heat your house. That has to be considered in the analysis.
