My main reason for asking is that I want to relay patio next to it. Which would involve digging down 10-20cm or so beside it for the sub base or drainage channels to be laid. I’m paranoid that disturbing it more would cause issues. But then I imagine the garden has been through many changes in...

Reviving my thread as I’m curious again. Photos attached this time of where I have done small test digs.. One corner. The left wall is the garage. The wall on centre of frame is the bottom of the extension. At first I was reassured I was seeing bricks deeper into the groin but then the appear to...

I don’t think so, not that I’ve noticed.. Issue is that one or two rads will have really poor performance - lukewarm to touch - bottoms of some rads lukewarm - can hold hand on them. Plus lots of gurgles, clicks, whooshing noises which do my head in and stop me using certain rads as they wake...

About 1.5 bar I think, it goes up to higher green zone when running

So I’ve seen the entire pipework run and it’s all pretty by the numbers. No offshoots, no redundant parts.. in fact a few in the ago the ‘backbone’ was entirely upgraded to 22mm from 15mm. Previous person to mess with it had installed two shut off valves in line to BR. These were also removed...

Not sure! One of the bleed valve in the pipework for draining doesn’t give any flow when loosened so perhaps that is dodgy but I’d expect a leak if that was the cause. In the pipework up to bathroom there is a 90 degree bend to get it away from the joist as it goes into ceiling.. perhaps this...

Not a clue, this is what I’m going nuts! My personal suspicion - and last straw - is that the two drops of pipes form upstairs to downstairs are still original and have not been replaced. They’re approx 15 years old and not a professional install. So I’m thinking perhaps there is corrosion...

No drips whatsoever - no corrosion signs or water on wall. I never see pressure rise (aside from ever so slight when it’s running)

I’ve done this. Last five days. I don’t get any air from the rads in the traditional sense (ie water comes out of bleed valve straight away). But the heating performance is poor. Trickling noises, especially if I turn all thermostats off aside from LR and EXT - then it sounds like a waterfall.

Yes I’ll need to re add water as appropriate

The red I get the most fizzy water from varies. It has changed over the years. For a long while it was only BR. But more recently I’m having way more luck with B3. Thr fizzy air will shoot out like a rocket, you’ll hear whooshing and spitting. Sometimes it’s rhythmic, like whoosh trickle whoosh...

Hi Just about to start work so I’ll reply to all your points later. But I do have to bleed with the pump on. If I bleed with it off, I just get water out. Nice gentle trickle. If I bleed with it on, I get the fizzing and farting water. I would think perhaps this is water I’m introducing by the...

That’s a bit difficult to quantify, the speed at which it gets worse. During winter it’s usually only off during the day, overnight. It’s left unused over summer. I’ve ordered some Bluetooth heat sensors so I can measure how fast it heats rooms and get some data on the speeds for comparison...

For the first three of four years being here I didn’t really touch the system apart from running it so I know what the symptoms elevate to. The rads all jsut get lukewarm, they don’t really output any heat to be worth a damn. I’ll have the heating running all evening and need a jumper. Rooms...

Never heard of this before; at this point getting tempted to try anything so it could be worth a shot.

Here's a paintmash. Yellow is walls. Red line is the piping route, representing both supply and return - they run in a pair each way. This is simplified being 2D of course but the connections and their positions, ie which radiators they are between, is correct. The worst rads are usually B3...

The air is never ending. The air only is quite brief.The air im getting out is mixed into the water. water will spray out of the system when bleeding, and it will fizz and spit and fart. its like the air is in the water. No external pump. I think theres an expansion vessel in the combi? filling...

I’ve always had it since I’ve moved in, persistent across boiler and new rads. Only thing the same as original is run of piping from boiler to upstairs, and a drop from upstairs to downstairs. I’ll sketch something up soon and post it so you can see the layout.

How would running a lower temp help? It’s near max. I think they’re ok as the boiler was professionally installed and it’s been checked various times. I can triple check. It’s like the flow reduces. The rads will be hot to the touch but the rooms don’t really heat. Living room will struggle...

Sorry I didn’t see reply alerts for this. Doesn’t appear to cause any pop sounds if I try to light it. Had an adey test on the system and it showed no abnormalities, other than inhibitor being weak (since I’ve been having to bleed it so bloody much no doubt).
