2019/12/30 · Pressure Change Range. Pressure will change when the unit fires up the heat. In most cases, it should rise to about 20 psi while its heating element operates. That's optimal at normal temperatures. Pressure changes of a few psi one way or the other can be brought about by atmospheric conditions. Most boilers are safe up to around 30 psi, at

2021/10/22 · 5. Turn the boiler back on. After the pressure has stabilized at 1 or 1.5 bars you should hit the main power switch to power the boiler back on. At this point, your boiler should be pressurized and run properly. If your boiler starts to lose pressure again, turn it off and contact a certified boiler repair person.
