I’m just opening up this topic for discussion.
Per unit of heat forgetting (minor-in-comparison) inefficiencies due to heat exchange losses, electricity is somewhere between 5 and 6 times more expensive when producing the same amount of heat as gas.
You can only insulate so much, but you still have to produce heat and even with significant improvements in insulation, the production of which incidentally adds hugely to carbon emissions, the majority of homes are not going to be be able to achieve anywhere near the 5x ratio which would equalise costs.
This means that total energy costs are going to rise massively for those who are eventually unable to use gas to heat their homes.
In a new build all of the improvements can be baked in from scratch (even though I believe even stricter insulation requirements for building regs may also be necessary), but eventually for the majority of existing homeowners who heat their water and homes with gas this could become financially catastrophic on so many levels and lead to a huge increase in fuel poverty.
You can’t just fit an electric boiler as a substitute in many cases without other very significant work being done, a huge percentage of houses don’t have the space for a ground or air source heat pump, and if I was a gas boiler manufacturer I’d be looking for alternatives...(and think of the price of spares too after the boiler manufacturers are decimated).
Incidentally no gas heating in 2 years means no gas heating sooner once the public realise the implications further down the line.
There are many things the government need to do to support this, but is the deficit from Covid going to cause significant impedance?
I’m not a fan of screwing up the planet with carbon emissions but is there is a reality check to be had here?
