I'm glad you laid out all the misconceptions about heat pumps!
> It's going to be hard to convince folks to replace their gas water heaters with electric heat pump models that cost ~3x more and save little to no cost annually.
Heat pumps are not "3x" as expensive and the price is coming down. Heat pumps are also a lot more efficient than any other heat source! Most households in the US would save ~$500/year on the energy bill if they switched to air-source heat pumps.

So it works like solar panels and electric cars — higher up front cost that saves you money over the long term. And if the government gave up-front rebates to make the costs the same or lower than furnaces then it's a no-brainer to use heat pumps.
>I'm not sure drilling for a heat pump would work in town here, and then the operating cost would still likely be more than gas (heating is at least 75% of my annual consumption).
Air source heat pumps are where it's at — waaay easier install than using ground-source or water-source. Air-source heat pumps used to not work in colder climates but now they do and have gotten a lot more efficient. These things are really awesome, a pretty good way to slash emissions while saving money over the long term.
- maxerickson 5y agoHeat pump water heaters are not the same thing as heat pumps used for home heating. Please edit your comment to make it clear you misunderstood what I was talking about. My expectation is that an air source heat pump would not work well here, at considerably higher cost than the gas furnace when installing is included in the comparison. Air source probably not working well is why I talked about drilling (each paragraph is a topic; water heating in the first and home heating in the second...).
