HI all, I am just about to fit a 10L Aquapoint11 undersink water heater to supply 2 outlets in a small office. The hot water pipework is mainly 22mm, about 10m, would I need to fit an expansion vessel, and if so what size and any one know where I can purchase one. The local plumbers merchants have a limited range, sometimes 5-10l min.
Kind regards
Archie

The instructions will tell you if you need an expansion vessel and the size required.

The instructions also has a expansion vessel detailed - which can be purchased from them.
