Got an issue with my gas back boiler thingy. It's a Potterton Fireside
"black Beauty" FWIW - in the house when I moved in, about 12-14 years
It had the same problem about 2.5 years ago - basically the pilot light
goes out - re-lights easyily enough - runs for a while - hours to weeks,
then goes out again. Eventually gets worse and worse. Got a man in and
he changed the thermocouple, but even then it still goes out every now
and then - until today when it seems back to hourly...
Any clues of what I can do myself before calling a man in? It looks
relatively straightforward from what I can see - I can identify the pilot
feed to the manifold, as well as the thermocouple - I'd not hesitate to
replace either if they were at fault - but I've no real experience of
this sort of fault - what's it likely to be - the pilot itself or the
thermocouple - or maybe something else?
The room itself is well ventilated, so I don't think it's lack of oxygen
or CO buildup. Pilot light burns with a blue flame (although I think
it's a bit "fuzzy", but I don't know if it's meant to be like that!)
Loathe to even think about a new boiler as it's otherwise sound and
has a functional (if rather ugly) gas fire attached, and is in a place
where running a condensate drain would be virtually impossible (middle
of house in an old fireplace!)
Any clues welcome!
