Hi,
I am in the process of having a new conservatory fitted. Part of this process involves moving a small radiator where the doors to the conservatory will be onto a different wall.
Now this little rad has been giving me problems for a while. It doesn't heat up fully (or at all sometimes).
During the moving process I changed the rad to a bigger one too. Now the problem still persists with the new radiator. When the heating is turned on the flow pipe is red hot, but the return is cold. I have checked that the values are open, also the valves are new with the rad, so should rule out faulty valves. After 15 mins or so the flow then goes cold and the rad has a very small amount if heat. Return pipe remains cold.
This radiator is the one furthest away from the pump, the living room one is also not as hot as the others but acceptable (prob 2nd furthest away). All other rads are hot and cannot touch for any lengthy period of time.
The pump is somewhat noisy to. Instead of a smooth pumping sound, it has somewhat of a beating noise to it, is this normal?
I have bled all the radiators and the pump, and when emptying the system the water is quite clear, no sludge as far as I can see (although the house is only 8 years old so wouldn't expect to see much)
From reading various posts, it sounds like I could have
1. Blockage in return pipe
2. Faulty Pump
3. ?
It's a sealed system running off a standard boiler (not a combi) and tank.
Sorry for the essay, but thought I would throw in as much info as possible.
Thanks.
