Hi Guys, need some advice please.
Posted this before a while ago, thought I solved it.
One rad of 15 is not getting hot, just warm, mostly at the top.
Told to turn All rads of and leave problem rad on.
Did, same result, still tepid, water just going round circs.
The inlet pipe to trv is very hot, but the rad at inlet point is cold, and top of rad tepid ?
Water is obviously getting through trv, so why is inlet point not hot as trv ?
I originally drained the rad to flush it, but water was clean ,so left it.
I suspected the trv must be faulty, blocked, so used last resort, Hammer, to clear it, pin is operating ok, didn’t,t open it when disconnected, which I should have to check flow!
opened lockshied when rad was empty, water coming out ok, so not blocked.
Used rubber mallet on rad to see if it was blocked, and try to loosen any crap.
I then re-balanced the lot, and it seemed to get a Lot hotter, thought, problem solved.
I have a long system due to shape the house, even the furthest rad which used to give me the same problem , is working ok now.
Now it’s the same, tepid.
Apart from the Trv, any suggestions of what to do next, apart from replacing it, and rad, but too cold to do that at present.
Don’t fancy trying changing it with system full, with my luck.
Don’t fancy draining system, and rad is not a standard size, it’s an old one, perhaps in spring will replace it, and a couple of other of same type.
Get the guy who services boiler to replace them.
Got me baffled I must admit,not hard
All other rads are fine now, even ones that were cool, after re-balancing, except this one.
It,s about third in the system from boiler.
Any hints at what I can try to get it hot, or just hotter ?
Does water in rads follow a route via the channels, or go throuhout to exit?
