What to Consider When Choosing the Best Electric Garage Heater

Location of the Garage Heater

The garage should always be located in a position where it can direct heat to the rest of the parts in the garage. But this is not always the case and this is why it is important to look at this aspect before purchasing your heater.

Ensure that the heater you are picking is able to direct heat towards your desired locations. Also, choose between a portable heater and a wall-mounted heater.

If you choose a heater that is mounted on a wall, that means you will need special hardware but it is also possible to get some with hangers to help in placing it in the wall or a ceiling.


This is the next big thing to think of. Some heaters will need to be hardwired while others will plug into the existing outlets with their power code. Also, the need for a professional electrician will be required for the hardwired option.

In all cases, it is important to have with you different tools and hardware. There are also portable heaters that do not need any skills or experience but only plugging in. I recommend this choice for a garage that has fitted outlets.

Safety Features

The electric heater is generally safer compared to those heaters that require fuel. For a safe heater, go for models that have heavy-duty housing because these are designed to prevent items from heating and causing fires.

Also, look for heaters with handles to keep your hands away and avoid burns.

Above all, look for a model that has a heat-regulating feature such that when the heater overheats, it can shut off automatically.


Sizing a garage heater will entirely depend on two factors; the power of the item and the room size. Measure the garages length and width to get the garages’ square footage. In a single square foot, 20 to 40 BTUs are needed.

Generally, a garage that is 400 square feet will be powered by 16,000 BTUs. So when you go shopping for an electric heater, get the one that is 16,000 BTUs and above.

Cost of Running the Heater

These are the most asked questions. To help answer this, look at various things including watts, utility rate, the number of hours you use it, state of residence, and product category.

The operation cost will be calculated based on the number of hours of use which is $0.65 for G73 and $0.73 for G56.
