Hi,
Have a gravity central heating system - Potterton Netaheat (~17 years old) in the kitcken with in/out pipes coming from airing cupboard on first floor (inverted loop?).
The following noises happen and I would like to know whether I need to be concerned or it is fairly standard stuff - perhaps just old or not great install??
In the kitchen I can hear a bubbling noise (air) in the pipes connecting to the boiler.
When the boiler and pump is on (either HW or CH) there is always whooshing and howling noises coming from an indeterminate place. It's not ear-splitting loud or anything, just constant.
Only one of the radiators, in a bedroom, emits a bubbling noise when the heating is on.
Other points: In the summer I emptied and cleaned the F+E tank as it had a load of rust(?) sediment in it. I'm going to get the whole system serviced after Christmas.
