Vokear Linear 24 water loss

[stevie135]

Hello

I have a Vokera linear 24 that has a central heating issue. Pressure in the system can start at 1.5bar then climb up to about 2.8 when heating up.
When it gets up there water starts to pass out of the safety valve. When this happens I loose pressure as the system cools and it cuts out.

Firstly - is this much pressure increase normal?
Secondly - if so is this a simple case of a passing safety valve?

Thanks for any help you can give.
