How often should I need to top up the pressure in the heating

How often should I need to top up the pressure in the heating system? When the heating system is cool, the pressure should be between 1 and 1.5 bar on the pressure gauge (the indicator needle would usually be in the green section). If pressure is below 0.5 bar (down in the red section), water has been lost from the system and must be replaced.
