Hi,
I am looking for some guidance regarding a problem that has developed with my central heating system.
A couple of days ago, the pipework started banging/knocking when the heating was going on and when it is cooling down, this banging can vary from a large thud to a series of regular bangs, the later usually when cooling down which then becomes less and less frequent until it stops - this has just started to happen, we have had the property for 3 weeks and was working with no banging etc until around 3 days ago.
Its an alpha combi boiler with radiators/heated towel radiators the radiators have thermostatic control valves (apart from one which doesnt)
I was wondering if anyone had a view/suggestion on what this could be before I have to call out a plumber/CH engineer.
I have looked online at things like, boiler pressure, pipes not properly clipped, air trap?!? All very confusing to me to be honest.
The boiler was installed in Jan 2011, and has a 5 year guarantee, I am unsure if new pipework would have been installed at the same point.
The crawl space sub floor is only approx 500mm so I am hoping it can be rectified without having to lift carpets etc, especially as some floors are tiled.
Regards,
Callum
