Best System Boilers 2021 - What System Boiler is Best in 2021? ### Sizing a New Water Heater | Department of Energy

Each boiler is given a boiler horsepower (BHP) rating based on the steam output capacity at 212°F and 0 psig. For this calculation, you will enter the steam load in pounds per hour, which will be divided by a constant of 34.5. This number represents the thermal energy rate required to turn 34.5 lbs of water at 212 °F to steam in one hour. ### Water Heating Calculator for Time, Energy, and Power

Therefore, to size a demand water heater, you need to determine the flow rate and the temperature rise you'll need for its application (whole house or a remote application, such as just a bathroom) in your home. First, list the number of hot water devices you expect to use at any one time. Then, add up their flow rates (gallons per minute). ### Boiler Sizing Calculators | Powerhouse
