Extra info - I’m finding that every 3 to 4 days the gurgling gets worse. The rad at the highest point then has a cold top and I can get about 4 seconds of air from it. After this it seems the whole system gets hotter. Interestingly I haven’t had to add any extra water to the system to...

Yeah sure. I get that. It’s generally quite simple under there. I should have got better photos. Perhaps later I’ll get some and draw where the pipes run. In this case I think it’s because getting a line of copper down the hallway would have needed a run of floorboards to come up and someone...

This might sound dumb but how would I check and confirm this? It’s all quite simple down there. A rad can’t be plumbed the wrong way right, just one end would be in and one end would be out, and they could be different on each rad? Ie as long as a rad is attached to both hot and cold, not both...

Is that a no go? Should it be all plastic or all copper?

My photos are awful but here is one of the busiest junction. It’s hard to show layout without a diagram of the whole system. This used to look tidier when it was smaller pipe, it seems busy now but it’s quite space constricted and without lifting more boards it’s hard to arrange it better...

it is barrier pipe, I can see it labelled in one of my photos

Probably. I think the entire system was installed circa 2010. New boiler, new rads except one in 2019. Pipework running along the hallway changed in 2024. So most of the system is ‘new’. In terms of design, it’s a three bed semi so there isn’t actually much pipework there! Pipes come out...

Here’s two videos of the rad noises. They can vary in frequency but this is what I’ll hear when either turning the system from cold, or turning off most rads except one. https://photobucket.com/share/8bbeb06f-dc80-4850-8f06-50f26c667733

It’s a Baxi duotec 28 I think, I will confirm..

Not fully sure what that is. There is only the boiler and circuit of rads. The other thing I forget to mention is that all my rads had locksheifl and thermostatic valve. On advice I removed the thermostatic valve from the bathroom rad so it has two locksheilds, so that there is always a path for...

I think I have in the past but the specifics escape me now. I can check again. I bet supply will be scolding hot and return all very very hot. I don’t think the boiler is at fault as the issue was present with last boiler, and fidgeting with the rads seems to solve. But I can check this next...

I’m not loving living with it Anyone I’ve spoken to is like ‘I’ve never seen this in my whole career’. The smart thermostats are a total godsend. I can at least remotely fart about with which rads are running to coax it into order, will look into some automations. This also demonstrates...

Issue is- central heating only gets lukewarm and does not heat house unless I turn on radiators in a specific order. If I don’t touch it, the house doesn’t really feel heated. Or it takes hours. If I I play musical radiators, I’ll cook my arse off within 30 mins. It’s also really noisy. Lots...

Most info is in my latest post. There is a diagram back there that may be useful. One stelrad vertical rad next to the boiler. I’ve isolated this (turned off both valves) and the system behaviour does not change. No designer. They are all boggo white panel radiators. Most are stelrad...

The stretch under the hallway floor upstairs is plastic push fit. It’s modern, installed by an established heating company. I don’t know if it is barrier, I only learned that this was a thing since last year! It is grey in colour if that helps at all. I haven’t inspected water colour this year...

I don’t think that there’s any issue with pipework directions. The boiler has moved location entirely, originally ot was in a cupboard upstairs but now it’s downstairs in the hallway. I’ve had two or three companies look at this and no one has noticed any pipework direction issue.. pipework has...

Thanks. Trades all seem surprised by this suggestion and often discourage it but I’m going to find someone that will just do what I ask. Do you have any advice on brand at all..?

Hello everyone. Time for my yearly fight with my heating system! It's exciting! It's unpredictable! It's a rollercoaster of emotions! I'll reiterate so that no one has to read through all these old messages. ISSUE Sealed combi boiler central heating system with 8 rads will run lukewarm if not...

As an update these disappeared in summer so they must have been dampness. Suspect condensation
