Fwiw, heat pumps are not comically expensive in operation. They also work in the north of Sweden, so I'm sure that any issues with low temperature operations have been hammered out by now.
I understand that installation can be prohibitively expensive in some markets still though, but this is a problem that can hopefully be addressed.
Sweden has some of the cheapest electricity in all of Europe thanks to all that hydro.
This year my final electric bill was ~ 25 c/kWh. Gas was ~ 8c/kWh (both after distribution costs, and funnily enough for electricity I pay amongst other things a fee to subsidize other people's solar panels' negative impact on the grid).
Not "comically expensive" but to be cost-effective a heat pump must average a COP of at least 3.1 (which is possible in most climates with a decent enough HP), so it's not yet a "jump on it first chance you get" kinda deal because it will take many years to recoup the initial investment. And people remember last year's winter where the electric costs were more than doubled; gas prices tend to fluctuate much less. This makes heat pumps even more of a very long term investment for people who can afford very large surprises in their power bill... Or who have excess PV generation capacity in the winter (that requires a very large house).
Gas is on the way out but all the political sabotage of electricity prices in Europe (nuclear phaseout, asinine financial regulations and fake competition with useless middlemen, misfiring PV legislation meaning PV owners are being subsidized by everyone else, etc.) means it will take a very long time before HP costs drop enough for people flock to replace their existing gas heater with a heat pump.
the other problem is that the electricity is less reliable than the gas (currently here).
Yeah, but gas heat still requires electricity, so that argument is not a great one, though repeated often.
Plus you can add a generator and reverse that advantage, as well as batteries. If you have an EV with a large battery that allows power out, that can be used as a good short-term solution.
An issue for sure, but one that can be remediated by the distributed nature of local renewable production and energy storage - something that gas by its nature cannot do.
