Hi there,
We have a problem with our heating. When we switch on the hot water our downstairs radiators get scorching hot..way hotter than our thermostat is set at.
We have a maintenance plan with British Gas and they have replaced the 3 way actuator about 5 times and even replaced the actual valve as well but it doesn't seem to make a difference. They have suggested it is sludge that's causing the problem and tried to encourage a powerflush but I have run sludge remover through the system and hosed through every radiator and the water runs fairly clean.
I have no idea why it would do this and it has done ever since we have lived here. I assume it must be just that the pipework is like that? I am willing to fit TRV valves on all the downstairs radiators but that seems like just masking the issue rather than solving it.
Any suggestions would be welcome. If it helps we have a back boiler system, a hot water cylinder in the spare room which is pumped. I really know very little about plumbing so sorry if i'm a little vague.
