Hi All,
I moved into my present detached house a few months ago ,since then I have noticed a humming noise (which has recently got worse ) it is centered in the upstairs bedroom where the airing cupboard is containing the pipework and an immersion boiler and what appears to be a new Grundfos pump. There is a Netterton Electronic boiler downstairs in the toilet area.The noise usually starts at about 11.00pm ish and goes on throughout the night till about 6.00am even though the boiler has been switched off completely in the early evening.It is a pulsing hum and carries on even after I have switched off all of the power to the house via the fuseboard thus eliminating electrical appliances etc.I have put Fernox into the sytem and bled all the rads of air but the problem is still there!.
Could someone PLEASE help a very tired site member ? Thanks all.
