Heat Line S30S Compact Pressure too high

[Eniltaeh]

A Happy New Year to all!

Heat Line S30S is just over two years old. The problem is that the pressure is reading around 3.5 bar. Drained of some water to reduce the pressure to the 2 bar, everything working well. Next morning the boiler needed to be topped up due to low pressure and not starting. Topped up to 1.1 bar and after warming up the pressure is in the red again and the process starts again.

The system is not leaking as it holds the pressure steady during several hours of operation.



Any suggestions would great...
