Having a few issues with our alpha boiler 4years old, had a bit of bother with it last year in the back end towards summer, no issues over summer months, now the cold weather has started, its started tripping again. Then again no heating has been on over the summer!

Recent consumer unit change, from old dorman smith series 17 with dual RCD, never had any issues with it tripping those.

The boiler is virtually right next to the consumer unit,16A rcbo 2.5mm twin and earth down the back of the wall behind C/U under the floor and back up clipped direct into a FCU, flex out to boiler, 3 amp fuse. Cable insulation test is clear.

Controls are wireless so no faults with control wiring.

The boiler does not drip when firing up, having a shower ect, we usually just go to the tap and have no hot water, to find RCD tripped.

Has anyone had similar issues, read a few post regarding condensation dripping into flue stat?

Thanks
 
@Croppie you must be gutted you don't have a ban hammer here so you could swing it like you do over at the plumbers forum when some one doesn't agree with you? Every one might hang off your every word over there but they certainly wont here :).....chump
Same owner on both forums,wind your neck in or i will get you removed from both
 
@Croppie....See us electricians and plumbers/heating engineers can get along sometimes :). Sorry I have to keep tagging you but for some reason I keep getting an error when trying to quote.
 
The thing is, Lee, we actually want to keep you right. I always make sure I speak with my sparkies on my jobs so there's no misunderstanding. The case is left off for them to do their work and then I go back to commission.

That way everyone is kept legal and above board.
 
Blimey what's happened to the forum now?? Let's not get back to the bad old days of di*****t et al. Daz
