Frequently Asked Questions
Common questions about Water Heater BTU Sizing, formulas, and expected usage.
How do you calculate water-heater BTU/h requirement?
A common estimate is BTU/h = 500 × flow (gpm) × temperature rise (°F).
Why include heater efficiency?
Input capacity must be higher than delivered heat when efficiency is below 100%, so efficiency adjusts required BTU/h input.
What is temperature rise in this context?
Temperature rise is the difference between desired outlet water temperature and incoming cold-water temperature.
Is this enough for final equipment selection?
Use this for preliminary sizing; final selection should also consider peak demand profile, recovery, storage, and manufacturer data.
