Before we dive into calculations, it’s vital to grasp the concept of BTUs. BTUs represent the amount of heat produced by a space heater in an hour. To find the ideal heating capacity for your space, consider the following factors:

  1.  Size of roomMeasure the room’s length, width, and height in feet. Multiply these dimensions to calculate the cubic footage.
  2. Desired Temperature Increase: Determine how many degrees Fahrenheit you want to increase the room’s temperature. This is known as the temperature differential.
  3. Insulation Quality: Assess the room’s insulation. Well-insulated rooms require less heating capacity, while poorly insulated spaces need more.
  4. BTU Calculation: Use the following formula:

BTUs = (Cubic footage of the room) x (Temperature differential) x 1.1 (for average insulation) or 1.3 (for poor insulation).

Wattage Conversion

Space heaters often provide their heating capacity in watts. To convert BTUs to watts, use the following equation:

1 watt ≈ 3.41 BTUs

Now, let’s illustrate this process with an example:

Example Calculation:

Imagine you have a room with dimensions of 10 feet (length) x 12 feet (width) x 8 feet (height). The room has average insulation; if you’d like to raise the temperature, you can increase it by 10 degrees Fahrenheit.

  1. Calculate cubic footage: 10 ft x 12 ft x 8 ft = 960 cubic feet.
  2. Determine the BTUs needed: BTUs = 960 cubic feet x 10°F x 1.1 = 10,560 BTUs.
  3. Convert BTUs to watts: 10,560 BTUs / 3.41 ≈ 3,100 watts.
Heating Capacity (BTUs)Coverage Area
1,000 – 2,000 BTUsUp to 50 sq. ft.
2,000 – 3,000 BTUs50 – 100 sq. ft.
3,000 – 4,000 BTUs100 – 150 sq. ft.
4,000 – 5,000 BTUs150 – 200 sq. ft.
5,000 – 6,000 BTUs200 – 250 sq. ft.
6,000 – 7,000 BTUs250 – 300 sq. ft.
7,000 – 8,000 BTUs300 – 350 sq. ft.
8,000 – 9,000 BTUs350 – 400 sq. ft.
9,000 – 10,000 BTUs400 – 450 sq. ft.
10,000 – 12,000 BTUs450 – 550 sq. ft.
12,000 – 15,000 BTUs550 – 700 sq. ft.
15,000 – 18,000 BTUs700 – 850 sq. ft.
18,000 – 24,000 BTUs850 – 1,100 sq. ft.
24,000 – 30,000 BTUs1,100 – 1,400 sq. ft.
30,000 BTUs or higherOver 1,400 sq. ft.

In this scenario, you’d require a space heater with a wattage close to 3,100 watts to heat the room efficiently.
