ELCTRICAL FAULT ON CENTRL HEATING Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

[TERVY]

I have a central heating / electrical problem. The system is a Baxi 45 backboiler and integral Baxi Barque fire front. The system is part gravity part pumped. The power supply to the heating is from a 3/5amp switched fused spur; Landis & Gyr electro mechanical programmer.

Problem. When I activate the heating via the programmer the fuse in the spur unit blows. The boiler has been serviced. Any ideas on what the problem could be. I know it all sunds a bit vague. I don't know whether to call in an elctrician or a heating engineer? :(

If you have hot water, and the fuse only blows when the heating is called for, then it suggests a fault with the pump.

I suggest you call your heating guy as it may need replacing, and the fact it has recently been serviced is probably incidental.
