worcester bosch boiler - pressure problems?

COLD- pressure is less than 1. demanding hot water trips the boiler.

I turn the central heating on and the pressure rises off the scales. (3+ bar).

The hot water from taps then works and slightly lower the pressure. What's going on? Help?

expassion vessel needs inflating or replacing as this compensates the pressure created by heating the water
