Cabinet Heater FAQs

What does the heating area square feet mean?

Square footage is the length of an area times the width of an area. Knowing the square footage of an area allows you to estimate the amount of BTUs necessary to heat the area most effectively. A generally accepted formula is: Square Footage x 40 = required BTUs. This is just a starting point. Ceiling height, building layout, and level of insulation will also factor into your BTU needs.
