Hi
I have radiators that won't heat up when all switched on. Individually they all work fine, but once all on, they're all cold. Pipework is microbore which is green with verdigris and so are the valves.
Boiler and pump work fine. Tank is a combined system on the first floor (one of the things with a coil inside separating one body of water from the other. Boiler is normal and not combi.
I have 4 of 11 rads on and they're tepid at best. Think I need a power flush. Have been quoted anything between 350 and 800. One chap reckons the trv need replacing.
Is it possible that they're the problem and replacing them might solve the problem without power flushing?
Had a flush in 2005 (only chemical I think) so unsure if it's the rads or the valves.
Any help much appreciated. I am wearing two pairs of everything, plus hat and gloves indoors.
