Oct 02, 2020 · It's normal for boiler pressure to rise as the boiler heats up, and fall as it cools down. The ideal boiler pressure is between 1 and 2 bars. But so long as the pressure gauge needle isn't going into the red zones, there's nothing to worry about.
Dec 30, 2019 · 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. It'll also kick off the power to your boiler. That can range from "inconvenient" to "aggravation" based on the time of year and your local climate.
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. Standard Hot Operating Pressure

Nov 07, 2019 · To increase the boiler pressure you will need to add mains cold water to the system using the external filling loop. Make sure that the boiler is turned off and completely cooled down before you start. You should only have to increase the boiler pressure once or twice a year.
This is where you want your boiler pressure to sit and if you're hitting well over 2.5, there is too much pressure in your boiler. Alternatively, a level that is below 1 indicates boiler pressure that is too low. However, sometimes normal usage can cause the pressure gauge to spike, reaching higher levels.
