noisy radiators

daz · 26 Dec 2003

We currently have a vokera linear combi boiler with full TVR system radiators. We have a very loud high pressure water noise coming through the radiators. The pump has been changed in the boiler to no avail.
Any advice / help would be greatly appreciated as the noise is driving us mad.

Can be the TRV's themselves. Some need to be on the right end of the rad (the flow end). Can also be that the flow is too high (turn down the valve at the other end) or that the pressure is too high (add an automatic bypass valve).
Checj the boiler instruction to see whether a bypass is required by the boiler anyway.

i am not a plumber or heating engineer, but like oilman i presume that when you saywith full TVR system radiators you mean TRV (Themostaic Radiator Valves) I was lead to believe that you should have 1 radiator with no trv (unless you do have a by pass valve)
