3 Easy Ways to Reduce Boiler Pressure - wikiHow
Typical pressure for a residential boiler serving a two story home would show 12 psi cold, and less than 30 psi hot. Over 30 psi boiler pressure will cause the pressure relief valve to open. Typical hydronic heating boiler operating temperature settings are LO-120-160 HI …
Oct 02, 2020 · Normal boiler pressure should be between about 1-2 bars . The ideal boiler pressure is often marked as a range in green on the gauge itself. With red indicating the low and high boiler pressure zones. Bear in mind that your boiler may continue to work if the pressure is in these red zones.
On these older systems the "automatic water feeder" is often a bell-shaped device which opens and sends makeup water into the heating boiler and its piping whenever the heating system's internal water pressure falls below a normal level (perhaps 12 psi when the boiler is cold).
Reasons why steam boilers flood, and where to look for
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.
