Hi
Looking for some advice. We have an old rad (8mm microbore) in hall which was never mega warm. Last winter i noticed it was cooler but eventually got some heat in it by adjusting the return valve on the rad & balancing some other rads.
Have turned rad back on after summer and no heat. Even if all downstairs rads are off it is nt heating.
Findings so far:
1) The TRV and pipe work to the bottom of the rad gets burning hot.
2) hot water gets to the TRV on the problem rad as quickly as it does to the rad in our living room (both around same distance from boiler and at same end of house) - pipes at TRV heat up at same time.
3) we have replaced the radiator and both valves.
4) if i turn either of the valves when refilling the system, we can hear the water filling the rad fairly quickly. Cant upload the apple video but when squirting the water into the bottle it squirted out quickly.
5) we get some heat to the top of the rad but not much else.
6) i have attached some pics of the downstairs manifold. All rads either branch off the side or end of the 22mm pipe EXCEPT the problem hall rad branches off the underneath of the manifold (you may see the pipework flowing away from the manifold in the 2nd pic).
We are going to get a plumber from my work to fix but what options do we have before lifting the laminate to replace pipe work?
Things we have thought we could get done:
1) there is a spare branch off the side of tge manifold - do we move the pipework for the problem rad to here first to see if the water has not had the opportunity to flow quick enough back to the rad.
2) disconnect pipework at rad and manifold. Put a hose on either end with a jubilee clip and flush water through both pipes to check for blockages or force out blockages.
If above doesnt work, coukd we drill a bigger home in the laminate, tape new pipe to the old pipe and pull back to the manifold. But would 8mm microbore go down throught the floor and bend back towards the manifold (at a 90deg angle) with just being taped to the old pipe.
Is there any options i haven't thought of?
Any advice woukd be greatly appreciated before i have to lift the laminate and skirting.
Thanks
