How do I calculate how many electric baseboard heaters I need?
When replacing or adding new heaters to a particular space, it is important to understand how square footage plays an important role in deciding how many heaters to purchase. Generally speaking, you need about 10 watts per square foot of space.
If an office space is 1,200 square feet...
- Multiply the square feet by 10 watts.
- You will need 12,000 total watts
- Measure each wall's width
- Lastly, determine the layout of your heaters. Will they go underneath all of the windows? How long should they be?
