What pressure should my boiler be when cold?
What pressure should my boiler be when cold?
between 1 and 1.5 bar
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.
