I've been told that my electric boiler is useless during a power cut.
Are Gas boiler C.H. pumps, timer and control electronics gas powered?

When I installeed CH in my last house - 1960s - I did try to find a 12v
pump so the we could cope during power cuts. No such luck

During the 3 day week power cuts in 1974 I recall my father rigging up
a generator to power the boiler - think he used a car battery to power
it.
