    How to Calculate Boiler Heat Input Rate | Sciencing

    How to Calculate Boiler Heat Input Rate. Depending on its energy source, a boiler may get its heat from the flow of electric current or from burning fuel. Each of these sources offer its own method for calculating the boiler's heat input rate. A separate method, however, works for all boilers. The boiler's

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

    Jan 19, 2015· A member of the Wall community asks this question: What is the "safe" operating pressure in PSI for a hot-water boiler heating system, and what is the "safe" range in terms of temperature for boiler operation? One member responds: The highest pressure the boiler should ever see is stamped on the boiler tag - Usually 30- or 50-psi.

    Steam is distributed via pipes to steam radiators, and hot water can be distributed via baseboard radiators or radiant floor systems, or can heat air via a coil. Steam boilers operate at a higher temperature than hot water boilers, and are inherently less efficient, but high-efficiency versions of all types of furnaces and boilers are currently

    Boiler Piping Flow & Pipe Sizing | HVAC Hydronics

    Boiler Piping Flow & Pipe Sizing - It is very important this is correctly done as too much flow rate reduces efficiency as described above and it can have detrimental effects on the boiler. All manufacturers of cast iron boilers want the Delta Δ T of the boiler with a certain range. Some are 20°F while others are 30°F.
