Features to Consider 

Before purchasing an electric garage heater, you need to ensure that it is suitable for your garage — your needs, budget, and installation requirements. 

Garage size 

The size of your garage is an important aspect to consider when choosing a heater. Your garage’s size directly affects the adequate power wattage and heating capabilities. Naturally, a more oversized garage requires a more powerful heater, and in turn a higher power consumption. 

The standard measurement to determine power consumption rating is the British thermal unit (BTU). One BTU is the amount of heat needed to raise the temperature of 1 pound of water by one Fahrenheit degree. 

The rule of thumb is 20 BTU per square foot. Hence, all you need to do is multiply your garage square foot area by 20 to see how much BTU you need. For example, if your garage is 50 square feet, you would need a heater that can generate at least 1,000 BTU,

Heating location 

Another factor to consider is where you want your garage to be heated. The heating location helps you choose an appropriate heater that fits your needs without incurring too much cost.

If you would like only specific areas to be heated, a radiant or infrared heater would do the job. Alternatively, a ceiling or wall-mounted heater is more appropriate if you prefer a central position for garage-wide heating. 


No one wants a garage heater that breaks down after one winter. Hence, you should factor the garage heater’s durability into consideration. 

A good determinant of the heater’s expected durability is its materials. If your heater consists of construction materials with a high-quality rating, you can expect it to be generally quite durable. 

One of the more recommended heater materials to look out for is stainless steel. Stainless steel is an excellent material for electric heaters because it is rust-resistant, can withstand extreme temperatures, and are more energy-efficient. 

Furthermore, stainless steel also has numerous safety features, such as being cool to touch, preventing overheating, and being easy to maintain.

Safety features

Any good space heaters should have safety features implemented to reduce potential hazards. These hazards can damage the unit, cause injuries, and cause fires. 

The three main safety features to look for are overheating protection and a cool-touch body. You should also get an electric garage heater that is easy to maintain. Most heaters are ceiling-hung, meaning that a heater that is difficult to maintain can cause accidents and painful injuries.

Overheating protection

Good electric garage heaters should shut off automatically when reaching their temperature threshold. Most modern garage heaters use built-in sensors to prevent overheating. 

These sensors protect the unit from self-damaging, which increases its’ durability. Furthermore, it also prevents any fires resulting from too high heat output. 

Cool-touch body

A cool-touch body for your electric garage heaters is essential for an accident-free heater interaction. You would not want to burn yourself every time you touch your heater. So, look out for a unit that exterior remains cool even in operation.   


Every electric garage heaters have their maintenance requirements; some only require some air blown to remove dust, while others require a professional inspection.

  • How often are maintenance checks and how much?
  • Does it take a lot of time and effort?
