Water Boiling Points at Higher Pressure - Engineering ToolBox

The boiling point of water depends on pressure. Online Water Boiling Point Calculator. The calculator below can be used to calculate the water boiling point at given absolute pressures. The output temperature is given as °C, °F, K and °R. Note! Pressure must be within the ranges 1-220 bara, 14.7-3200 psia, 760-165 000 mm Hg or 30-6500 in Hg.

Boiler Pressure Problem #1 Best HVAC Troubleshooting Tips

Dec 30, 2019 · In any event, the usual cold pressure of a boiler should sit at about 12psi (pounds per square inch). Most pressure gauges display different-colored zones. If the needle sits much outside the green zone, particularly on the high side, you have a problem. Pressure Change Range. Pressure will change when the unit fires up the heat.

3 Easy Ways to Reduce Boiler Pressure - wikiHow

Jan 19, 2015 · 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. A 15-psi setting will lift the water to 34'.
