My central heating system has the vent pipe to the expansion tank positioned in the boiler return pipe. All modern diagrams have it in the flow pipe, just before the cold feed and pump. I understand that this is because of current regulations.
My question is .... what is the reason for the change and would there be any benefit in changing the position of the vent pipe from the boiler return to the boiler flow when I have a new boiler installed?
Thanks for your advice.
