Boiler Chimney Height Excel: Getting chimney height right is vital for safe boiler operation and good draft. Our free Excel calculator uses simple stack‑effect formulas so you don’t have to. Just enter the flue‑gas temperature, local elevation, and chimney material. The sheet then shows the minimum chimney height above the roof and the correct flue diameter. With this tool, you avoid manual errors and meet code requirements every time.
How It Works
This calculator applies the basic physics that drives natural draft. It factors in gas density, outdoor air temperature, and site elevation. As soon as you enter your boiler’s output numbers, it spits out the chimney height needed to prevent downdrafts. It also sizes the flue so gas flows smoothly without condensing. You can tweak your inputs—like boiler power or roof height—and see results update in seconds.
