  • What Causes High Pressure on Steam Boiler — Heating Help

    Oct 31, 2014 · A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.Learn More

  • What Your Boiler Pressure Should Be When It's Heated

    Dec 30, 2019 · To find the optimal pressures, consult the manual that came with your boiler. But if that's lost, most boilers are so similar the pressure differential between them is relatively minor. 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.Learn More

  • What is the safe pressure for a hot-water-heating system?

    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'.Learn More
