Never mind the EVCPs, what about the boilers.

Chris Pearson
Apparently gas boilers should be banned from 2025.


At the moment, well under 10% of our energy is supplied by electricity: it is mostly gas. Use of an electric vehicle could double our leccy consumption, which would be bad enough; but (a) trebling the cost of our energy would be painful, and (b) how would the network and generation cope?

    Ground source heat pumps are a thing.  One option is to dig up the lawn and bury a long coiled hosepipe ("slinky") under it.  The other option for people with smaller gardens is to drill a number of deep boreholes.  Either way, this allows you to suck heat out of the ground during the winter, allowing it to recover in the summer.  But it's expensive and/or disruptive to install.  And if you make the ground source too small, the ground will eventually freeze solid, and the COP will plummet.


    Water source heat pumps also exist, but are only an option of you have a river at the bottom of your garden.  One National Trust house saved a fortune replacing the old boilers with heat pumps that suck heat from a handy river.
