System Pressure keeps building in worcester bosch 28cdi?

The system pressure keeps going above 4 bar until I release water through valve in radiator, with hot water off it does not build up. Non return valve fitted to hot water pipe serving mixer shower recently fitted. Any advice?

Isolate cold water mains going to the boiler and monitor (for a few hours) if problem stops, your domestic hot water heat exchanger needs replacing.
