Here in the UK a heat pump disaster is unfolding because the government are pushing hard to get people to install them, yet despite this very few are doing so. The main problem is the cost and also the great disruption to the home with the necessity to replace radiators and pipe-work. There is also more insulation required in many cases. So, faced with all this the public are reluctant.
There is also another issue - that the government has not ruled out the possibility that hydrogen may be used to replace natural gas (methane). If that was available as an alternative then I am sure nearly everyone would opt for it, as most gas boilers can be adapted to run on hydrogen and all the radiators and pipe-work would remain the same.
The question is - when will the government make the decision as to whether this is going to happen and when and where? The longer the government delays the longer the public will hold off from deciding as well. Currently hydrogen is being used in small trials of 100 houses and there are plans to go to larger trials if this is successful. But this is likely to take some years. Then there is the cost and availability of hydrogen. Hydrogen does not exist in any quantity underground, so it has to be manufactured and stored.
Either way the people will have to pay. Read more about this here:
