Key Considerations Before Buying Electric Space Heater for Garage

There are a few considerations that you should keep in mind before purchasing an electric space heater.

The Power Rating Of the Heater

The first thing that you should consider when selecting an electric space heater for your garage is the power rating. Electric heater manufacturers state the power rating of their heaters and this information should be readily available on the packaging. The higher the power rating of an electric heater, the more warmth it will provide. Therefore, if your garage gets pretty cold during winters, then you should get one with a high rating.

Type of Heater

There are three main types of electric garage space heater.

  • Fan-forced air garage heaters : The fan-forced air eclectic fans are best used for smaller rooms. They work by forcing air to pass-through an element that has been heated thus creating the feeling of warmth. They warm the room gradually but their heat is evenly distributed.
  • Convection garage heaters : Electric convection garage heaters work in the same way as a fan-forced electric space heater. The difference is that with the convection garage heaters, the heat rises without the help of the fan. Due to this feature, they are much slower in heating up your garage. Many of the convection garage heaters are portable.
  • Radiant garage heaters : As the name suggests, radiant garage heaters use infrared heat to warm up the garage. The level of heat that a garage heater produces depends on the size of the heater. Smaller units direct the heat to a particular space. Larger units are usually mounted either on the wall or the ceiling and do provide heating to the entire garage.

Safety Features of the Heater

Safety should take preeminence when using any electric appliance because the danger of harming yourself through electrocution or starting a fire is high. The same case applies to electric heaters since they can be a health hazard. For this reason, many electric heaters have safety features. For instance, they come equipped with a tip-over switch. The switch turns the heater off should it tip-off for any reason.

Other heaters have a mechanism that prevents them from overheating should they get extremely hot. Another safety feature that will also protect you from burning is the cool touch feature. With this feature, the outer parts of the heater do not get hot. This feature is important especially if you have kids or pets.


The other important factor to consider when shopping for a garage electric space heater is the portability. There are two main types of garage heaters – portable and mountable heaters. As the name suggests, portable heaters are lightweight thus easy to carry from one place to the other around the garage. Portable heaters provide heat to limited space.

The second type is mountable heaters. These heaters are often large and they are either mounted on the wall on the ceiling. As opposed to portable garage space heaters, mountable heaters provide warmth to a larger area.

Additional Features

Another factor to consider when selecting an electric space heater is additional features. Some heaters come with an adjustable feature such that it is possible to direct the heat in a particular direction. This is made possible if the heater has a pivoting mechanism that enables you to direct the warmth towards a particular direction and set the heater at a certain angle. Another additional feature is the ability to change the power setting of the heater from high to low and vice versa.

Ease of Installation

Another factor to consider when selecting a garage heater is the ease of installation. Heaters can come either preassembled such that you can start using them immediately or they will need some assembly. If you do not have a problem with following some assembly instructions, you will not have an issue even if you buy one that requires an assembly. The good thing though is that the assembly process is not complicated. Other garage heaters need to be connected to the circuitry. For these types, you need to use the services of a professional.
