Calculate the Heating Load Capacity of Electric Garage Heaters
Electric garage heaters can be purchased in a variety of sizes and colors. They are effective in heating small spaces within the garage or larger areas, depending on the size. These types of heaters are usually inexpensive to purchase and fairly easy to install. To calculate the heating load capacity of your electric garage heater, follow the advice below.
1: The Determining Factors
Pay attention to the labels that are with the garage heater. You may see a label that claims the garage heater will heat up to 300 square feet. However, it does not take into consideration the following factors:
- Is the garage insulated
- What type of climate do you live in (i.e., Florida as compared to Maine)
The above factors are important considerations.
The load capacity of electric garage heaters is also determined by the voltage. A 120V heater will produce significantly less than a 240V heater. A 240V heater typically will heat up to 400 sq feet of garage space, whereas a 120V heater will heat anywhere from 150 to 200 sq feet.
3: Load Capacity
Your outlet may not be able to handle an electric garage heater with a higher load capacity. You need to check the wattage output of the heater (information contained in the manual) with that of your electric service. Make sure you don't overload your circuit or you will have to upgrade your circuit to match the load you wish to utilize.
