Roaring Noise From Central Heating
2 Answers
In the summer I had a combi boiler fitted which meant getting rid of the old water storage tank system. The new boiler was only used to heat water until last Sunday as the weather was warm and has worked perfectly. The boiler is wall mounted on the outside wall of the integral garage.
This week the CH has been used and whenever on , you can hear a noise like a roaring furnace.throughout the house
As mentioned when only heating hot water, there is no noise.
It isn't the sound of the exhaust gases venting outside.
When I stand next to the boiler, it doesn't seem to be that.
All I can think is that it is the pump or pipes. Are combi pumps integral ? {Ideal logic plus}. It there a way of bleeding air out of the pipes or do you have to bleed each radiator?
I'll get the installer back but any ideas appreciated.
Thanks

Quite possibly the pump speed has been set too high. Yes, the pumps are usually integral. Since this is the first time the heating has been used with a new boiler, all you need is to bleed out any air, balance the rad valves, and adjust the pump speed. Yes, bleed at each radiator. This often happens with new systems that haven't been used fully yet.
