No problem, just curious.
If I have a sealed central heating system with the expansion vessel charged at 1.5 bar, what actually happens? When the system is on and heating and reaches 1.5 bar, does the expansion vessel allow more room for the water expansion and hence keep the system pressure constant?
I guess what I am asking is what is the relevance of the vessel charge?
Thanks
