Vaillant Ecotec Pro Expansion vessel

[heritage]

Hi All,

I have quite a few old radiators connected to the above boiler
and I now need to install another one, but I am worried that the expansion
vessel will not be large enough, can a second one be fitted if so how

Thanks

teed into the return to the boiler

Hi again can the vessel be fitted just anywhere in the return leg

 

[kevplumb]

yes as long as there are no valves on the pipe between the vessel and boiler

ie it can't be isolated

Hi does the expansion vessel have to be for that specific boiler as I have a spare one that was for a boiler that was removed, the old one is from a worcester bosch 24i combi but not condensing
thanks
