Steam Basics | CleanBoiler.org

To go from 212F water to low pressure steam requires another 970 BTUs per pound. Increasing the pressure increases the temperature of the phase change and increases the amount of energy the water/steam can carry. At pressures higher than atmospheric more heat must be added to water (sensible heat) before it can turn to steam.

What Should The Boiler Pressure Be When The Heating Is On?

When the heating is turned on your boiler pressure should be between 1.5 and 2 bar. Most boilers will highlight this area on the pressure gauge in green to help you see if the needle is pointing to the correct amount of pressure. Some boilers will also have the critical zones below 1 and above 2 marked in red to help you identify any issues.
