Got a customer with no hot water or heating topped pressure up and was fine on hot water. Put it on heating and pressure goes from 1.2 bar to 2.8 bar in no time at all. I’ve heard about faulty expansion vessels with these. Any ideas? I’m fairly new gas safe engineer and mainly do installs. Any help here would be greatly appreciated, still learning

Expansion related issue, not necessarily the vessel itself. Would look at the communication pipe. Netatec are crap imho.
Start it again in the gas safe only forum and you'll get more advice.
