Hi Folks,
Boiler Type: Glow Worm Ultimate 50 BF
This is the first winter we've been in our new house and as it's been very cold the last week or so, so we've had the boiler thermostat knob up on full. Occasionally, after it's been alight for a while, a loud roar can be heard from the boiler which is not normal. To stop the roar we've turned thermostat knob to 0, waited a few minutes and then whacked it back up to full. Quite often the roar can be heard again after a few minutes.
After the roaring noise and with the thermostat knob on 0 (i.e. no demand for heat/gas) I've removed the front case and noticed an orange flame from the rear of the combustion chamber area, no noise though just the flickering orange flame. Pressing the gas control button for a few seconds puts out the orange flame.
The boiler has been recently serviced and I'm going to call him back. Just wanted to know if any of this is dangerous, expensive to fix, and would really like to know what is causing the problem. If I had to guess I'd say the main gas injector was 'sticking' on slightly.
If you need any more info I'll be please to give it if I can.
Thanks for your help, Mark
