Hi everyone. I moved into a new house last year and I have one cold radiator. It’s the furthest from the house, in an extended part of the dining room.
When we moved in we needed to replace the boiler as it was on its last legs. But still it was cold.
So I bought and fitted a new rad, in case it was sludged up. But still it was cold.
My third plumber told me the house needed to be balanced. And that in order to do so - given the valves were old, was to replace the valves and add TRVs to the whole house. In his words he said ‘in my career there’s never been a radiator I couldn’t fix with balancing.
Needless to say, it’s still cold. And I’m £750 lighter.
Any ideas on what could be the problem? The rad can get hot, if you drain it. But as soon as the system is depressurised it will cool. Freezing at the bottom. Very luke warm at the top. The return pipe always stays cold. The flow warm.
I asked the plumber if the return pipe could be blocked and whether we could flush air / water / powder to try to clear it. But he says microbore won’t survive that and the joints could blow across the whole system.
So I’m stuck. Because it’s an extension it’s simply too cold to be a useful room without a working rad. And replacing the pipe work would be a lot of work because it’s buried in a flat roof and exterior walls.
Any thoughts welcome!
Thanks. Dave.
