Hi,
I have just had a new Halstead boiler installed and it has been working correctly, however there is a loud bang coming from the boiler/pipes when the boiler switches off the central heating. We have no problem with the hot water.
The boiler is a Halstead 30HE combi boiler.
We have radiators on the system as well as under floor heating. There are 3 isolating valves on the hot water side of the central heating that are triggered by 3 thermostats we have in the house for different zones, separating our radiator system and the 2 under floor zones.
I was wondering if it might be air in the boiler somewhere as I have blead all off the radiator system and the noise is still there.
Any advice would be must appreciated
