Hi
My CH is unusually noisy and I'm wondering if anyone else has had a similar experience. I've had a couple of plumbers come and have a look with no joy.
All the radiators in the house have TRVs. The Worcester combi boiler supposedly has an automatic bypass fitted. There are no separate wall/room thermostats.
When all of the TRVs are turned on full, the noise from the CH is acceptably ambient.
However, when I turn down one of the TRVs to a lower setting (in the kitchen, for example), this seems to create a blockage for the entire system.
The gush of circulating water in all of the radiators gets (and stays) very, very loud and is accompanied by a high-pitched whine. This reverberates throughout the entire house and sounds like a huge strain on the system. The only cure is to turn all the TRVs on full.
Any ideas?
Thanks for your suggestions.
