Seems to be the EV, I have an 8ltr vessel, I will fit it externally to see if this solves the problem.. Many thanks Martyn.

I have a problem to solve with a Alpha CB50, the pressure rises within 1 minute to 3bar when heating is on, vessels are all pumped to correct manufacturer pressure. Has anyone come across this fault? The flow heats up, pump runs and hot water gets hot.. Many thanks Martyn.
