Ours also makes a loud bang when the pump first kicks in. However I'm also experiencing issues with circulation and balancing, and in another thread the suggestions I've had indicate an air lock or blockage. I've got a plumber coming round tonight with a view to replacing the radiator...

Thanks for the comment, More experimentation today and I managed to get all the downstairs radiators warm (some more than others) and the bathroom still remained hot. In fact I set the thremostat in the hall to 23C and it reached this and cut the heating off as it should, although it did...

What bypass valve ??

Dave, thanks for your help, I might try draining the system and re-fill, however I think that if it was down to an airlock I would of come across it when I tried bleading the rads. I can't work out why the pipes would be really hot one side of the valve, but the rad side it would be either...

Dave, could I trouble you (or anyone else for that matter) on a further development. After much fidling about last night I managed to get one of the downstairs rads in the living room luke warm, the downstairs hallway rad red hot, upstairs bathroom rad red hot, and bedroom 1 and 2 rads were...

Dave, thanks again for your comments Yes the valve is three way, and works fine as this afternoon I tested the system by selecting just the HW and felt the pipework to see if it was being pumped correctly. It was as the feed to the rads was cold by comparison. I then selected CH/HW and the...

Dave, once again, thanks for the tip. I like this site, after you post it suggests several other threads of similar subject :roll: I have a heat mat so I'll take your advice and run it all in copper. At the moment the boiler is in the downstairs loo, and all the pipework from it to the...

Guys, I'm looking at replacing the old pipework to the radiator circuit and fit some new rads at the same time. I want to keep the existing copper pipework in the airing cupboard, so in essanace I want to connect to the 22mm copper feed and return pipes and connect the new pipework to them...

Dave, thanks for your continuine support. I've been round trying my best to check for circulation by closing off lockshields where I can get to them or just opening the rad valves where the lockshields are not accessable (like behind the bath panel). I've also tried bleeding them and all I...

Yes, last night I could feel the hot water progressing through the pipes when I turned it on, and if I undo the large "nut" in the middle the impeller can be heard rubbing the casing. I've also removed the cover and checked that nothing is broken (by that I mean physically hanging off or...

Dave, thanks for the tips. I've just been out and purchased a new digital room stat, and whist I'm not getting overheat problems the system still seems to be working in a strange way. Can you tell me if this is the correct operation I've set the boiler temperature dial to approx half way...

Dave, I've also notived that the room-stat is acting strange, often it has to be moved up to max before there is a click, and this morning both the neon on on the stat and the boiler ON light was flickering (boiler wasn't running either) Can you elaborate "aps" I have no idea what you are...

Hi, Is there such a device as a digital room-stat rather than the ones that use a bi-matalic strip. Most of the ones I've seen have such a wide variation between the switch on / off range Malcolm

Thanks for the reply, Strange this is that last week we had an un-related problem with the gas cooker and called transco out to check the pressure.. the guy said then that these were prone to PCB failure... wish he had kept his mouth shut !! Anyone have any links (apart from e-bay) for...

Seems I'm the only one adding to this thread :) Strange thing... the first radiator after the pump is the bathroom one. Because the cowboys who put the system in couldn't be bothered to move it, the only way I have of regulating this rad is to shut down the feed valve as the balance valve on...

OK an further update. The boiler has been off for two hours, pressed the advance button on the controller to turn the CH on. Moved the room-stat so it called for heat, boiler on light came on, as did the fan etc and the boiler ran for about 30 - 45 seconds before it stopped and just the...

Hi, first post so please be gentile ! 5 years ago we moved in to our home, and withing weeks the old Wickes Bolier packed up. We got a guy in (it was just before christmas) and he quoted over £2K to rip out the old boiler and install a new one. Regretfully I was not around whilst the work...
