Hello everyone.
A 2 y/o closed central heating system is working but is a continuing source of puzzlement for me.
One of the topmost radiators keeps accumulating gas of some kind. The system has been pressurized at 2.4bar and all radiators checked for air. 2 months on and the water pressure is 2.2bar + I have just bled gas in one of the radiators (nearly all height of the medium radiator).
I can't be drawing air from the atmosphere because the system is under a higher pressure. Right?
Can the system be producing gas from some sort of a chemical reaction?
Thanks.
