Thank you for the replies. This boiler was installed 4-5 years ago and we have had no trouble with noises or anything before so I assume all the proper bits are in the right places. This TRV has been off 90% of that time with no issues until now. We do have a radiator with no thermostatic valve...
Recently I have noticed a strange noise in the mornings from the CH that I would describe as like someone using a petrol chainsaw in the next garden down as heard through double glazing. Its a low vibration noise thats not very loud but loud enough to be annoying when your trying to sleep...
Hi, we had a valiant combi boiler and some new radiators put in about 2 years ago and since day 1 we have been having issues with the wireless room stat either not turning the heating on or off when its supposed too.
About 70% of the time it works fine and it seems random when it doesn't work...
