The Sultana – Part 2: How do boilers go boom? – Equipment

Apr 06, 2015 · Putting it in perspective. Water in a pot on the stove boils at 212°F. As pressure increases, the water's boiling temperature also increases. For example, at an operating boiler pressure of 145 pounds per square inch (psig), water boils at a temperature of 363°F. If there is a break or leak in the boiler, the pressure inside immediately drops.

Gas-Fired Boilers - Code Compliance Brief | Building

Boilers are typically between 75% and 96% efficient in the primary process of heating the water, but any un-insulated heating water piping will lower the overall efficiency of space heating. In addition to the boiler unit, a gas-fired boiler requires a feed water supply, a boiler loop/heat delivery system (e.g., hydronic radiators or fan coil
