Gas boilers

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?


You can power those from a small generator.

So all houses with a gas boiler have a small generator?

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

Most domestic gas boilers include a low power DC generator.

Does that have enough power for the AC CH Pump?

Not by a very long chalk.

Mine does and a UPS but possibly not the norm for a non DIY person to take sensible precautions against inconvenience.

So not a lot of use in a power cut then?

Some of us do though my CH is oil. You could also use a redundant UPS for the modest load that the CH pump, burner and controller represent.

But very useful after a gas cut.

Couldn't you use a match - far cheaper?

I have the boiler, cooker and micro, which needs electric. The hob works without, if I use a match and a gas fire with no need for electric. In the drive I have the caravan to fall back on in the drive, it can use its own gas for heat, battery to ignite and blow. It has a gas cooker and hob, battery ignition, battery lights. Three way fridge freezer. So that is my final backup option, for an extended power loss.

We have an EV. Always keep it fully charged in the winter months. If we do get an extended power cut in extreme whether we can go and sit in the EV and use the heater to keep us warm, and have hot soup. 40kWh goes a long way!

You might have had some joy at a chandlers, but your wallet would be bruised.

If they want to keep warm. I have one now.

don't live that near the sea.

Not sure mine has. The old one that I took out had two thermistors and an expansion bulb device for the final overtemperature trip.
