Thank you - at least it doesn't sound like this ol ' boiler needs open heart surgery - what approximately could I expect to pay for a service, new TC :?:
We have a Thorn M Gas Fired Boiler ( I suspect the boiler should be about 20 years old ) The boiler works perfectly in almost every way - except the pilot flame goes off every 2 to 3 days (normally during the night) and I then have to re-ignite the pilot flame. The pilot flame does ignite again...
