Dec 30, 2019 · In any event, the usual cold pressure of a boiler should sit at about 12psi (pounds per square inch). Most pressure gauges display different-colored zones. If the needle sits much outside the green zone, particularly on the high side, you have a problem. Pressure Change Range. Pressure will change when the unit fires up the heat.
