Hi
I did that and all bar one were working. The next day 2 rads weren't heating up so had to fiddle with it again. The rads seem to have a mind of their own and is a constant struggle everyday messing about with the rads.
Im going to do this today. Will gett back to you. Dads been in hospital for last week so haven't had time. You've been really helpful so far. Really appreciate it.

Some other things to try....
Remove all the TRV heads (some may have failed capsules).
Exercise the valve pins up and down (some may have become stuck/sticky).
Leave heads off and run heating (pins in fully up position means valves are fully open).
Drain the system and eyeball the state of the water that comes out.
Add some chemical cleaner and run it round system for a week or two.
Drain down again and refill with an added inhibitor.
If you get some Calchem, it is both a cleaner and inhibitor and can be left in.
If there is a magnetic filter, clean it out. Add one if there isn’t.
What size are your pipes? 15mm or small bore?

Hi
I've checked the valve pins before. One was a bit tight but thats okay now. Pipes are standard size whatever that is. I was told by my builder. In terms of draining the system, that is too technical for me. I would need step by step guidance.
Been really ill for 2wks. Measures rads and the total btu is 57548. Thats well under what you said for a 28kw boiler, but I think my boiler is 24kw.
