Hi all, My house was built in 2001 and the central heating system is piped with grey micro-bore pipe. I have three radiators which will not get hot, one upstairs and two downstairs. All were working fine at the end of last winter. I have tried all of the usual methods to get them to work but with no success. I spoke to my local plumber yesterday about the problem when he came to connect a gas fire for me and he said it was most probably the pipe work that was blocked and the only solution was to re-pipe with barrier type pipe. He said it was not possible to power flush this type of system. The radiators are full of water so 'my logic' says it is obviously getting through the pipes. Is he correct and is that my only option. I would be most grateful for any views on this problem.

Thanks for the quick reply. Not sure what or where the manifolds are?

If thermostatic radiator valves are fitted then check pin isn't stuck down.
Yes I did that and all of the normal stuff. Thanks for the reply.
If you re pipe try to use 15mm the flow will be better and you can flush 15mm
Thanks 'oilboffin', that's the plan at the moment.
Further to this problem, I now have access to the pipe work under the floor and can see that the central heating circuit is Hepworth 15x2mm grey plastic pipe. The rads are fed from the 15mm pipe by grey microbore pipe (8 or 10mm I think). As I have said previously my problem seems to be the microbore pipe having no barrier in it. Will the grey plastic 15mm pipe have the same problem and need replacing or can I just replace the microbore? Any advice appreciated.
