The EU regulation is about industrial use of fluorinated greenhouse gasses.. I don't think that will ban other refrigerants

  Yeah you can use propane, isobutane, ammonia, or CO2. The first two are flammable, the second is both. And CO2 requires higher pressure. They aren't as nice from a safety or operations standpoint but ain't the end of the world really. Although they are now way cheaper than fluorocarbons.

    The CO2 heatpump needs more than 150 bar, like having a small OceanGate in your attic.

      More like having a medical oxygen or welding gas tank in your attic (except with a much less reactive gas).

        Or like a convenience whipped cream dispenser. Quantity and geometry certainly makes one more volatile than the other, but the number alone isn't all that far out.

    Huh? Propane is quite easy to deal with, though? Besides being flammable, but that merely means you have to ensure it gets sufficiently diluted in case it feeds indoors, doesn't have an opportunity to asphyxiate occupants, and isn't eager to burn the house down in a typical catastrophic malfunction. Unlike fluorocarbons, you don't need to worry about leaks beyond the flammability/asphyxiation aspects, and could conceivably flare excess/contaminated charge off (just to prevent an explosive food from being able to form), with no environmental worries beyond the burning/flaring of fossil fuel (and whatever contamination the oil contributes). Might not be legal in a particular jurisdiction, but I assume that's a product of fluorocarbons being the norm and them being an environmental issue to leak, supporting a blanket ban on leaking any.
