One pipe central heating system

[nwgs]

Having a rethink, is yours plumbed through the rad, as on pipe in and one out. Or is it as per Stems pic where it’s linked together below the rad

I don't know. I am a humble 78 years old disabled pensioner.

I know nothing about it.

The radiators look just ordinary to me.

All I want to do is get some heating when the radiators go lukewarm.

I can only say again that I don't know and I can't understand any of it.

I can just about turn the radiators on, that is all.

(I haven't given any pictures you mention)

 

[JamesEB]

Can someone tell me what to do please when I turn the central heating on and find there is very little heat and the radiators are barely warm.

Thanks.

Turn the boiler thermostat up perhaps.

Does this help the one pipe system?

Yes, because the radiators will be being supplied with hotter water.

The boiler is always run on the highest setting and there is virtually no heat.

Then it may be full of sludge, badly installed, etc., difficult to diagnose over a forum. I think you need to engage someone competent to physically come out and inspect it.

I have a one pipe system in my home (large 1960's 3 bed detached, 9 radiators, plus 2 two towel warmers) and had planned to replace it with two pipe after I moved in, I only had time to convert the first 3 radiators to 2 pipe before the first winter came but not the others. However, it worked so well that after the first winter I left the rest on the one pipe and they are still there now, 21 years later. The only difference I notice is that the radiators on the one pipe section take a bit longer to heat up from cold, but they do get hot, maybe not quite as hot as the two pipe rads, but pretty close.
