Gas boiler parts

My boiler is a similarly aged Gloworm. The flame sensor is, hopefully, replaceable by a universal replacement thermocouple which can be obtained at B&Q for a few pounds (I replaced mine recently) - they fail quite regularly. The pilot light assembly is an entirely different matter. They do get rusty but if yours is actually falling to bits, you may have a problem. The pilot thermocouple is probably in series with the other safety device, the boiler overtemperature cutout. These can fail as well.

The pilot system is generally fail-safe, ie the problem is keeping it going, not stopping it going when it shouldn't be. If the pilot light is staying alight, and the boiler is operating correctly, I would leave well alone. I hope, when you had it to bits, you gave the heat exchanger fins a good clean out. Allowing these to soot up is a Bad Thing. It would be worth buying a universal thermocouple as it's bound to go when the shops are shut!

Yes, they're called central heating merchants

More information than "Glowworm, I think" might be useful when trying to get parts

Yes, well. I obviously wasn't going to turn up at the shop and tell the man 'Gloworm - I think' was I? I was just asking for names of shops that sell this kind of stuff. I didn't think B&Q had this kind of thing - they don't seem list pilot light assemblies on their website. And I couldn't think of any where else - I'm sure Homebase hasn't got this stuff!

Google is your friend: 'Glow-Worm pilot spares' (without the quotes) will give you some leads

try

or try:

Both do mail order, most of the info you'll need to give will be on the boiler's databadge, or possibly on the front cover of the boiler.

At 15-20 years old you're approaching the point where parts become obsolete, however both of the above companies (owned by the same people) specialise in getting hard to find parts ;)

(Ok, ok, I do some work for them ;) )
