Garage Heater Size Calculator
FAQs
How do I calculate what size heater I need for my garage?
Calculating the size of the heater you need for your garage involves considering the garage’s square footage, insulation, desired temperature rise, and local climate conditions. Here’s a general formula:
- Calculate the garage’s square footage: Measure the length and width of the garage and multiply these numbers to get the square footage.
- Determine the desired temperature rise: Decide how much warmer you want the garage to be compared to the outside temperature.
- Consider insulation: If your garage is well-insulated, it will require less heating capacity compared to an uninsulated one.
- Find the heating capacity (BTU/h) needed: The formula is: Heating Capacity (BTU/h) = Square footage * Temperature Rise * 20 (for well-insulated garages) or * 30 (for uninsulated garages).
Keep in mind that this is a rough estimate, and you may need to adjust the BTU/h based on your specific situation and heating preferences.
