Hi i have a Valliant combi boiler Ecotec plus 834 when the rads are off the pressure is fine but when you turn the rads on it rises into the red to the limit ! When you turn it off it goes down to the grey scale. Is it safe to use the boiler i turn it off for 45mts then back on again.

Read the FAQ's regarding pressure vessel checks and recharging. Do that before using the boiler and causing excessive pressure.
