We have a Glow worm boiler which is at least 7 years old. For the first time, the pilot light has gone out several times in the past couple of days. It goes out after about 15 minutes.
The pump is fine, but at the moment is pumping cold water round.
Does anyone know if this is a big (expensive ) problem or if it sounds like it could be fixed easily?
Any help or advice much appreciated!
