    Central Heating Nightmare - Air in System Daily

    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...

    Central Heating Nightmare - Air in System Daily

    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

    Central Heating Nightmare - Air in System Daily

    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...

    Central Heating Nightmare - Air in System Daily

    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...

    Central Heating Nightmare - Air in System Daily

    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...

    Central Heating Nightmare - Air in System Daily

    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...

    Central Heating Nightmare - Air in System Daily

    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...

    Central Heating Nightmare - Air in System Daily

    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...

    Central Heating Nightmare - Air in System Daily

    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..?

    Central Heating Nightmare - Air in System Daily

    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...

    Is this normal - drip marks on breather membrane in new roof

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

    Drain - can I drill the grey area?

    I don’t really have space for a soakaway far enough from a boundary. I’d be making the hole through the side, on one of the vertical faces.. I don’t see it as being much different to directing other water flow this way, ie if I put sink waste into it from above? Not that I’m doing that but...

    Drain - can I drill the grey area?

    Ok thanks. Trying to confirm if it’s silly idea to drill the grey concrete area but I can’t see that it would cause a problem unless I was really aggressive or unlucky!

    Drain - can I drill the grey area?

    Hi Thinking of adding drainage to garden. Don’t need or want a 4 inch soil pipe for this, it will only be run off from a small patio. Looking at aco hex drains which appear to have small pipe outlets - I need to confirm this but they appear like internal water waste piping like from kitchen...

    Extension - extra foundation/footing?

    Hi all Looking to lay a patio next to a 3x3m approx brick single skin extension, mid 70s vintage. I'm being careful as I'm suspicious of the foundation quality and depth, and current working theory is that it is a raft foundation. I pull up old patio on one side next to it and find this...

    Priming slurry for Indian sandstone - cement and SBR or ready mix slurry

    Hi all I’m laying some patio and a right of access path soon. I want the patio to be solid but the right of access path, jsut good enough. I bought ready made priming slurry(pavetuff) but I do have SBR and cement. I was going to use the ready made slurry everywhere but ofc it will cost a lot...
