Heat pumps only work on their own in mild climates. Cold climates still require furnace in conjunction with the heat pump. Good luck convincing anyone in the northern United States of getting rid of their furnace or hot water heater. Spouting this sort of head-in-the-clouds, wrong information only weakens your cause.

“WHERE DO HEAT PUMPS WORK BEST?

Heat pumps are more common in milder climates, where the temperature does not typically drop below freezing. In colder regions, **they can also be combined with furnaces**for energy-efficient heating on all but the coldest days. When the temperature outside drops too low for the heat pump to operate effectively, the system will instead use the furnace to generate heat. This kind of system is often called a dual fuel system – it is very energy efficient and cost effective.”

This is the same as "hybrid" cars. It seems like a sensible halfway point but once you try it you find that just going fully electric has many benefits.

Like for example, if you're going to go to the expense of laying gas pipes for those furnaces, why not lay a geothermal loop instead and use that to boost the heat pumps output?

And, like the "EVs don't work in the cold" claim, there's lots of experience outside the US of EVs and heat pumps working well in cold climates. You might need to insulate your house or stop actively subsidizing fossil fuels to make it happen in the early stages but it's totally doable.

Heat pumps are fairly popular in Scandinavia where it gets quite cold, they fall back to resistive heating when it gets below -20°C, I think.

I live in the Great Lakes with a heat pump heating in a drafty Victorian house. The heat pump came with resistive heat strips but they only kick on a few days a year.

Once I airseal some more and fix some of the leaky storms I expect it to never resort to resistive at all.

Heat pumps do work in cold climates.

and imagine it wasn't a drafty victorian, but rather a new build passive house with incredibly good insulation. One would probably be fine with the heat pump alone.

You have left this comment multiple times in the threads, in comments that have nothing to do with heat pumps:

The only thing you are showing is your ignorance everywhere.

Why are you talking about heat pumps?

If you have remote heat, you don’t need a heat pump.

Heat pumps are expensive, and hard to service and maintain (though they usually have a long lifetime). Some of them use pretty toxic chemicals that you don’t really want leaking.
