To make up for this we are thinking of replacing the bathroom
radiator with an electrically assisted towel rail - so that
it can be switched on when the heating is off.

You can run it off the unzoned pipework instead of the heating zone.
This
way it will get hot when the hot water is heated, or when the heating is
on.
This is good, because you often want a warm towel after a bath. Running
the
bath makes the radiator hot as the cylinder is reheated.

If you do go electric, ensure it is fed via a 30mA quick acting RCD. If
there isn't already one on the circuit you are proposing to use, install
an
RCD fused spur.


Thanks for that (thanks to IMM & rob too).

If I fit an appropriate RCD, does this mean that I can site the towel rail
whereever I like - eg right next to a bath or shower. Or are there regs or
codes forbidding that?

Installing an electric towel rail when you have a gas heating system doesn't
sound that logical at all.
