Hello
Had a new rad fitted in my flat, since then the boiler has been making noises on CH startup and HW usage. CH startup getting worse..at first I honestly thought a plane had flown over my house (about 3 seconds of noise)..now it sounds more like a really sad elephant (about 5 minutes of droning and wailing).
Noise stops when I call HW
Boiler is a precondensing Vailant turbomax 824
I (not an expert) think sediment has somehow got into main heat exchanger..
Just wondering if
1) the game is up - need a new HE
2) this could have somehow been avoided in rad fitting if the system had been drained/filled differently?
Thanks. Feel sorry for my neighbours at the moment when the elephant starts at 630am..
