What To Know When Buying A 240V Electric Garage & Shop Heater

Where To Place Your Heater

The placement of your heater largely depends on the type you have. If you have a large fan-forced heater you should place it in the coldest part of the room. This can easily be determined with a thermostat if you are unsure.

Keep Away From Flammable Items

With an electric heater, it is important to watch out for some obvious dangers. Garages and workshops are often places with flammable and combustible items. Be careful by placing your heater around 7 ft from the ground and away from any such items.

Consider The Size Of  Your Space

When discussing what garage heater to purchase, it is important to know which space you need it for. Smaller garages require significantly lower power and voltage than large commercial spaces.

Portable Or Wall / Ceiling Mounted?

Electric heaters can usually be divides into free-standing portable heaters and ones that are wall or ceiling mounted. Portable heaters are usually smaller, more practical and easy to move from room to room, while ceiling mounted evenly distribute heat in large areas.

How Much Power Is Necessary?

For an average 2-2.5 car garage, purchasing a fan-forced heater with 45000 BTUs would be perfectly reasonable. When it comes to infrared models, it takes roughly 30 000 BTUs to heat up that kind of space. It is important to check the amount of thermal output before buying your heater.
