Boiler Sizing Calculators | Powerhouse

Feb 01, 2010 · In this example, our outdoor design temperature is -10°F and indoor design temperature is 70°F, thus our ∆T = 80°F, the net area of our R-19 wall is 155 square feet (less the area of door and window), the U value of that wall is U= 1/R19 or U 0.053 x 155 square feet = wall heat loss of 657 Btu/hr.

Steam Heating Process - Load Calculating

May 18, 2018 · Here are the basic steps in how to design a boiler: Calculation of boiler Heat Duty. Using desired steam parameters, calculate the enthalpy of steam to be generated; Multiplying enthalpy with the rated steam generation, obtain the total heat value of steam at rated steaming (boiler heat duty) Boiler heat duty is expressed as MKCal/hr or MW or HP

One BTU is approximately 1055 joules and is defined by the amount of energy required for heating or cooling a single pound of water by one degree. Here is a simple to use formula. It is not intended to be the standard of truth, but it will definitely give you an idea of what direction to take in planning your HVAC system: Heat Load Calculation
