Well actually Ian, it was all thanks to you guys that I didn't go ahead and allow HUG to cut a piece of pipe work out, make a mess, have to re-paint etc AND pay them £450 AND STILL HAVE A COLD RADIATOR! So thanks everyone for your fabulous advice which made me doubt it was a blocked...
Hi everyone,
Just an update on my cold lounge radiator (which only got hot if I turned 2 other rads off). F
Finally had the time/money to call a local heating engineer out. He diagnosed the problem immediately over the phone! Guess what? It wasn't a blocked pipe - the radiators simply needed...
Well actually he soon realised that the TRV wasn’t the cause of the cold radiator but changed it anyway as it was stuck down. Then put some inhibitor in somewhere and did some other things! He was here about 3.5 hours in the end.
Only the vertical pipe that comes down from upstairs. All the pipes under the radiator are cold. Although when I turned all other rads off and turned heating up to 30 the pipe in was v hot and the pipe out was luke warm.
So an old combi Baxi boiler came out (not sure of model but I do know it was smaller in litre capacity) and a Worcester Bosch 30i went in. Just a straight change, nothing else altered.
Now I have turned heating back down to 20 and put all the other radiators back on, the lounge rad is stone cold...
The valve was already fully anti clockwise and can’t go any further. Now I have turned the heating down to 20 and turned the radiators back on, the radiator in question is luke warm at the top and cold at the bottom.
When you say valve you mean this?
It is Home Utility Group in Leeds. Their customer service is shocking - never replying to emails and not returning calls etc etc. Yes the radiator definitely worked before hand. But because I unfortunately don’t know anything about central heating systems, I don’t know what is usual practice in...
I think we have established that there is a blockage in the pipe. The pipes under the radiator are not hot and the pipe that runs into the room from upstairs is warm but the one that runs out is cold (I think! ).
