• ### Boiler – Fundamentals and Best Practices

STEP 3 SELECT THE BOILER The size of the replacement boiler will be based on the Total Heat Loss of the building calculated in Step 2. The boiler should be selected based on its Net I-B-R Rating in BTU/Hr. For example, if the Total Heat Loss of the house is 85,000 BTU/Hr. then the Net I-B-R Rating of the replacement boiler must be at least 85,000.

• ### Boiler Sizing Calculators | Powerhouse

The BTU/hour to Boiler Horsepower calculator is used to help size both steam and hot water boilers. This calculation translates the heat transfer input requirement to BHP. To do so, we divide the BTU/hour by a constant of 33,475. This constant represents water being converted to steam, which is 34.5 pounds of water multiplied by 970.3 BTU/lb, or latent energy. For this calculation, you will enter the BTU/hr of …
