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).

Yes, it would be prefab panels. I want them to go between concrete posts so slot into place.

All good advice here. I’ll certainly consider the battens on the rear of the fence. Perhaps add an additional one above my cut out to supplement any others. Arris rails look like the battens on the rear? I don’t really mind what’s in the rear of the fence. My assumption was it would be a...

Standard dull white Stelrad. One of them is a vertical Stelrad. This has never really caused an issue. When I wasn’t bleeding them regularly - or only letting out the initial blast of air and not getting fizzy water - one or two rads would be almost stone cold. The bottom of the rest would be...

I’ll try this again to confirm. Experience has told me that I simply don’t get anywhere doing it with it off. I might get a tiny blip of air but I then never get the ‘air inside water’ fizzing and spitting happening. If I don’t get that, nothing changes. When I get this fizzy air, I then get...

Yes I’m a bit suspicious of this. My last thought is to replace the final bit of pipework running up from the boiler. I suspect it wasn’t a professional job. Everything else has been replaced - aside from one rad - so I can’t see how the cause could be elsewhere.

No. It’s all quite simple. There used to be an upside down U bend which I suspected as contributing to the problem but I had that removed, and it has made no difference.

If I bleed with it off I don’t get much out. And then the radiators don’t get hot. Trial and error has shown that I need to do it while it is running. A downstairs radiator makes loads of gurgling and trickling noises. I have to leave this one on, all others off, and then bleed from an...

Nothing leaking. No signs of leak on ceilings or on floors. Been under the floorboards multiple times and no signs of water dripping or leaks there either. Pressure never rises on its own and it doesn’t drop, until I bleed them. Water that comes out is like an orange colour. The longer I leave...

I'm having continuous issues with my central heating. I've tried all sorts and there is no improvement so I'm reaching out online to see if anyone has an ideas or if anyone has experienced something similar. To put it simply, there is always air in the system that I can never fully clear...

thanks. yes depending on how the panel is constructed I'll need to pay mind to the battens in that position!

Hi all For various reasons not worth going over in too much detail I need to install new fence panels along the edge of my garden. There is a step/sharp change in elevation along the way - think two normal bricks tall. My instinct was to install a fence panel that ends at the step, post at the...

This this is basically it. If anyone is doing things in the kitchen right now you can’t really hear the tv in the living room!

Thanks to all responses. In terms of type of block, do I need to pay this any particular consideration - ie if it’s too heavy, is my wall going to sink or similar!? The wall is original to the house. Other houses in the same development/road have a solid wall here, or a small (0.5msq) serving...
