In today’s video, Alex from Mr. Heater works with our friends at Summit Racing to educate people on the various portable heater options available, and how to determine which is best for a particular work space.
The most important thing to pay attention to is the BTU (or British thermal unit) rating — which measures the amount of heat a portable heater can produce.
Generally, the heaters with the highest BTU ratings will be the most expensive.
A common formula for determining how many BTUs you want for the space you want to heat is:
Square Footage (building length multiplied by width) x 40.
If, for example, you had a 500 square-foot garage, you would multiply 500 by 40, making a 20,000 BTU heater a solid choice.
Forced Air vs. Radiant Heating
Portable heaters generally come in one of two variants — forced-air convection, or radiant heating.
Radiant heaters heat objects.
Forced air convection-style heaters heat the air.
Both have their advantages depending on your work space, your personal preferences, and how often you’re using it as an outdoor heater.
