Is there any gas guys out there who can assist me? It's a Baxi Bermuda back boiler, GC 44 075 08. I replaced the pilot light/ ASD assembly because it wasn't igniting. That's all sorted but the asbestossy O ring between the part I fitted and the gas solenoid valve had disintegrated. I replaced it with something else but it's overheating. I've tried everywhere to get a parts list but no luck so far.Where can I get one of those asbestos type O rings? It's about 6mm i/d, 12 o/d, 4mm ish thick. If I had the correct material I could punch one out.I'm hoping there's people here with materials knowledge.
We had a Baxi Bermuda for years. One day I noticed mould spores just above the skirting board beside the chimney breast. It got worse over the next couple of weeks. Eventually the laminate floor began to buckle. It turned out the cast iron heat exchanger had cracked and was leaking but because it was set back in the chimney and behind the fire front you couldn't see it. The leak was also running down between the floorboards and the laminate floor above. I bought a new heat exchanger and had it fitted, £600! About five years later the electronic ignition unit failed, quoted another £150 plus fitting. A mate who worked for British Gas told me not to bother as back boilers are so inefficient, something like 90p in every £1 goes up the chimney. We bought a condenser boiler and it was a real game changer, no more waiting for 20mins for the rads to heat up, it was almost instant. Our gas bills also went right down as well.My brother also has a Baxi, he's been told his is life expired but you can no longer fit back boilers without special permission and only when you can prove you cannot fit a more efficient boiler elsewhere. I don't know how true that is or if it's British Gas trying to get work?Ours is in the loft but actually more accessible than in the chimney behind a gas fire.
