Hi,
I have just fitted 2 new rads to a conservatory off the main circuit. When I charged the system up, all worked well and they warmed up nicely. Its on a combi boiler and both rads have new TRV's
Now a day later they refuse to get warm. What are the possible solutions and causes. Airlock? The rest of the house is toastie warm.
Also, just a general question, I have heard a few people say a few rads will not get warm. I don't believe a powerflush is the answer as its been a more recent issue rather than a build up. I suspect a faulty TRV or blockage somewhere. Now the question is, lets say its a faulty or stuck normal wheel head valve, how do you determine that the valve is at fault or lets say there is a blockage in the pipe leading upto it somewhere. Obviously taking the valve off is an option but a drain down is necessary and its not guaranteed to be the problem. You could be replacing a perfectly good valve.
Thanks in advance Sam
