Dec 30, 2019 · High pressure can result from the boiler temperature being set too high. Higher pressures generally cause automatic shutdowns. Modern boilers have built-in pressure release valves. These generally trip at 30 psi and release excess steam to bring the pressure back to normal. Itll also kick off the power to your boiler.
How to Set Hot Water or Steam Heating System Pressure
Nov 07, 2019 · Depending on the make of your boiler, the recommended optimal working pressure by most manufacturers is 1.3 bar. We would always advise checking your boiler manual to make sure your boiler is operating at the optimal working pressure.
Jan 19, 2015 · The maximum pressure I am allowed it to get to is 30-psi, because, at that pressure, the pressure relief valve will open. This is typical of residential hot-water boilers. As far as temperature is concerned, my boiler will shut off if the temperature exceeds 205 F. THey do not want the water
The standard cold water operating pressure of most U.S. and Canadian hot water boilers is 12 pounds per square inch (psi). If the boiler pressure drops below 12 psi, the valve will allow new water into the unit to bring up the pressure reading.

Boiler Gauges, how to read the temperature & pressure
The operating pressure of a heating boiler (hot water or hydronic heat) is read at the pressure and temperature gauge (see above) and controlled by. The starting or "cold water" pressure at the boiler - typically at 12 psi is for typical U.S. / Canadian residential heating systems normal cold temperature starting pressure. U.K. and european heating systems should be pressurized to between 1 and 1.5 bar
