We often say that a boiler’s pressure should be at around one bar, but this is only when your central heating is turned off and you are not running any hot water. When your boiler starts heating up water, the water expands (think of how steam takes up more space than water), which causes the pressure gauge to jump up.

Feb 08, 2011 · The static pressure of a boiler depends on two things (That I know of): how hot you make the water and how high you need to pump it (change in elevation). 20-pounds is probably a fair value for your system, but you'd need to provide more info to be certain.
For safe operation of any fuel gas fired steam boiler: Combustion is monitored and controlled to avoid creating an explosion inside the combustion chamber. Boiler steam pressure and water level are monitored and controlled high pressure or low water level could destroy the boiler.
Troubleshooting a Hot Water Pressure Washer: Part 1. The ignition spark is distributed by two electrodes in the firing chamber of the hot water boiler. These electrodes receive voltage from the ignition coil which is part of the Mi‑T‑M patented E-M-F system. The main problems that could impact a proper ignition are incorrect gapping of electrodes,

The water pressure in a hydronic boiler shouldn't be over 12- to 15-psi. It should have only enough pressure to raise the water a few feet above the top of the highest point in the piping system. A 12-psi setting will lift water 28' above the fill valve.
Both gas and oil fired boilers use controlled combustion of the fuel to heat water. The key boiler components involved in this process are the burner, combustion chamber, heat exchanger, and controls. The burner mixes the fuel and oxygen together and, with the assistance of an ignition device, provides a platform for combustion.
