Probably a daft question, but...

Hello,

I'm a bit of a 40-watt bulb when it comes to DIY to be honest, so here's probably a very easy question...

As of this morning, our central heating keeps cutting off the house electrics. I can switch on the socket which serves the thermostat, timer and boiler OK, I can switch the hot water on and it fires up fine, but as soon as I flick the heating to on, the electrics cut out at the main switch. We've got a Baxi 552 back boiler, if that helps.

My question is, do I need a heating engineer or an electrician?

Cheers!

Take yourself down to B&Q and they'll give you an energy-saving version of yourself. I could do with one of those!

I suggest a heating engineer, because the culprit is usually the pump, which a sparky wouldn't change. Diagnosis doesn't need a bright spark, you disconnect it and see what happens

I would suspect one of the following is at fault
1) pump, water getting into elecs, but only if the hw is gravity
2) motorised valve, either an internal leak or its quite common to have a pump valve leak and drip into mv
3) room stat, to test room stat turnit right down then turn ch on at timer, if electrics dont trip turn up room stat, if they trip then its either 1) or 2)

Thanks for the prompt replies. I tried the thermostat thing and it only trips when I turn it up, so it'll be options 1 or 2 by the looks.

Thanks again.
