> who will pay for any repairs or replacement? That's what nobody wants to hear about - that heat pumps are massively complicated technology not only expensive to purchase and install but also requiring regular maintenance, in particular also heat exchangers with the low diameters we've come to expect from modern heating equipment requiring decalcifiers and other consumables. I don't know about UK but let be assured in Germany it's as bad or even worse, with plumbers and other craftsmen lacking, energy prices very high (heat pumps, like any compressor, requiring lots of power), and the government sticking fingers into their ears, doing absolutely nothing but drafting completely unrealistic energy consumption projections. Switching to heat pumps would require tens of decades alone, not including the rebuilding or insulating of a large part of houses to make this even remotely effective, which isn't feasible due to interest rates, etc., etc.
