You ask for the GC No. It is 35 075 03A
Yes, I did. Thank you. I'll get our gas engineer to change the thermocouple and see if that fixes it. Can I let you know if it does before rating your reply?
OK. I'll rate it now and hope the problem is solved!
Just an update on the gas wall heater that you advised us about. Our gas fitter fitted a new thermocouple probe as you suggested, but there was no improvement. The manual for the heater said change the mag valve if it won't stay alight. We bought one online for £30 Unfortunately again there was no improvement when it was fitted. Our fitter phoned Baxi and they said he had done all that was possible and they couldn't help further as the model was no longer in production which wasn't very helpful! We have now had to scrap the heater.
Thank you. However, I wasn't aware that there were any new ones available? We have two others of the old type which are working OK, but if either pack up, we will have to get new ones. What would they be?
Thanks for your further thoughts which we shall consider carefully.
