Hi All,
I've got an upstairs radiator in my house that won't heat up. In an effort to sort the issue, I've tried all of the following, but none have resulted in the radiator getting hot:
- I've bled all of the radiators in the house to expel any air, especially in the cold rad - this rad is full of water;
- I've tried turning off all of the TRV's around the house, leaving the cold rad only open, and have tried the circulating pump on different speeds to see if I can clear any obstruction. The rad did not get warm;
- I've tried shutting the TRV on the cold rad and with the lockshield end open, I have drained approx. two litres of water from the bleed valve until warm water came out. I repeated this process, closing the lockshield and opening the TRV. Again, I drained about two litres of water until it ran warm. Clearly warm water from the system is able to reach the rad from both ends;
- I have tried balancing the system, turning all of the lockshields off on all of the other rads in the house, then just opening it a quarter of a turn. This has resulted in the cold rad getting slightly warm, but nowhere near warm enough to warm the room;
I'm at a loss what to do next. The water running from the rad is a light brown colour - I understand the correct colour considering it has fernox in the system. It is an 18 rad house, so quite a large system, but I cannot figure what else to try to get this one to work.
Any suggestions on this would be greatly appreciated!
