Hello,
I have a micro bore central heating system, fed by a Baxi 105e
combi boiler, which was fitted 2 years ago.
The heating system itself, radiators and pipework is approximatly 15 years of age.
I have a loud humming/whining noise from the central heating pipe work.
This has happened since the boiler was fitted, along with thermostatic valves to the radiators.
I did read that it could be the thermostatic valves, so I turned each one off in turn to see if it helped but with no difference to the noise.
Is this the right way to test, or do I need to remove the Thermostatic valves and shut the radiator valve off completly ?.
I also took some flooring up and noise appeared to be coming from the manifolds and pipework .
The noise starts as soon as the central heating comes on and continues even with the flame off but the pump still running.
I have read the info on this site, regarding central heating noise and in particular humming in pipework.
From this it would appear to be the pump, either the mountings, speed of the pump or too much water pressure in system.
The pump mountings appear to be o/k and the boiler is only 2 years old,
the central heating pressure is 1.5 bar, which I believe to be correct.
Can I adjust the pump speed on a Baxi 105e combi ?.
Could anybody tell me if there is anything else I should be looking at ?.
I would be grateful for anyones help/opinions with this problem, as it is driving me mad.
regards Feebee
