Never mind the EVCPs, what about the boilers.

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?

  • Whilst the use of heat rejected from power stations sounds attractive and is regularly proposed, it seldom makes economic or engineering sense.

    A modern power station rejects heat at very low temperatures, often less than blood heat. This is too low for domestic or similar heating. The volumes of only slightly warmed water needed would be vast as would be the energy used in pumping this water.

    Water at such low temperatures requires either heated floors, or improbably sized radiators to transfer enough heat into the rooms.


    Heated bathing pools are a possibility, but how many of those do we need ? Thermal desalination of seawater is another possibility, but demand is limited.
