Therefore, this leaves the 120V electric garage heater as the commonest heaters in most households. Also, these heaters are more convenient in terms of space and efficiency. They can be mounted permanently or placed strategically such that it can move around.

If you are looking for a 120V heater to warm your garage, we have done comprehensive research about several brands. The information below will help you make the best choice from a large pool of these products. In as much as all garage heaters aim at eliminating cold for you, there are many other basic details you should consider.

Types of 120v Electric Garage Heater

Electrical Garage heaters belong to two broad categories. The classification is based on the mode of heating and portability. On portability basis, there are subgroups; fixed and portable.

  • Fixed Garage Heaters : These heaters are permanently mounted on the wall or on the ceiling with fasteners. Mostly, fixed heaters are hard-wired to the electrical system. So, to install them, you might need professional assistance to assemble them.
  • Portable Garage Heaters : Portable garage heaters are the easiest and most convenient for warming your garage. Instead of mounting them permanently, they are placed on strategic positions and they can be moved around. In most cases, they don’t require assembling. You just purchase and plug it to start using. Under this category is where most of the 120V electric garage heater fall.

Classification Based On The Mode Of Heating Leads To Three Subcategories:

  • Radiant Heaters : Radiant heating is the most popular mode of heating in garage heaters.  They use electromagnetic waves to transfer heat to the objects lying on their path. Transfer of heat to only objects makes these heaters more convenient and effective especially in large spaces. They also generate heat quickly. The major drawback associated with radiant heaters is that they are more expensive compared to other types. The most popular example of radiant heaters are the infrared garage heaters.
  • Convective Heaters : They rely on high resistance electric elements. A current heat up as it passes through this resistant element. The warm air is then thrust out to the cold room and replaced with the cold air from outside. The convectional circulation of air in and out of the heater keeps the room constantly warm. For increased efficiency, some heaters use built-in fans to quickly push air out and even distribution in the room.
  • Micathermic (Mica) Heaters : Mica heaters use a special heat-conducting stone called mica. It is this stone that surrounds the heating element which is more powerful than that used I convective heaters. Mica plays very critically in the functioning of this heater. It helps in transferring the heat from the heating element to all parts of the room. Also, when heated it generates electromagnetic waves. These help to increase the warmth in the room. Basically, mica heaters have both radiant and convective heat.

How Do I Choose a 120V Electric Garage Heater?

When purchasing your garage heater, there are basic features you should put into consideration. These will guide you to make the best choice depending on your needs. They include;

  • Size : The size of your room should greatly influence the size of your heater. If you buy a too large hater when your garage is small-sized a lot of energy will be wasted. On the other hand, a small heater isn’t effective for a large garage either. Therefore, you should go to a heater that best suits your garage size.
  • Efficiency : You should test the efficiency of the heater before purchasing it. Make sure that its output equals that claimed by the manufacturer. It will save you from spending a lot of money on a non-efficient heater. You can also base your assessment on customer reviews; these give you a glimpse of the product’s efficiency. A product with many negative reviews is worth avoiding at all costs lest the next will be yours.
  • Price -to-Feature Ratio : Weigh the cost of a heater and compare it with the features. An efficient heater with advanced features may cost you more. These go hand in hand. These guarantee more comfort and a long lifespan. Although this doesn’t mean that all cheap heaters are not efficient, it will all come down to the level of efficiency and comfort you want. There are very efficient heaters that cost cheaply. All you need to do is cautious and informed to get a product equivalent to your money. Some shops may want to exploit you and face disappointments later when the heater doesn’t perform to your expectation.

Factors to Consider When Choosing a 120v Electric Garage Heater

  • Wattage/BTU : The fact that you are shopping for a 120V garage heater doesn’t mean all of them are rated the same. Different units have different wattages and others in terms of British thermal units (BTU). You’ll find 120V electric garage heater rated at 1500, 1200, 2500 wattages, etc. Therefore, it’s prudent to consider the rating you want before making your choice. Note that; the higher the unit wattage/BTU, the great the heat value.
  • Size of the garage : The size of your garage plays important role in the choice of your heater.  A heater required to warm a 500 Square feet room isn’t the same as for 200 square feet. If you are looking to heat a room between 400 to 600 square feet, a 120V rated at 1,500 watts is enough. Other factors such as insulations and ceilings should also be included. The good thing is that the garage heaters display their commended coverage area.
  • Ease of installation : In terms of installation, you should consider whether you want to use the DIY method or professional technician. The fixed garage heaters are always the hardest to install and you’ll need to hire a qualified technician. If you don’t want to incur such extra costs, you may go for the portable ones. These are easy to install as they are not hard-wired.
  • Convenience controls : Features that give you more control over your garage heater are worth considering. These include the digital displays, remote controls, and timers. These give you the freedom to control your garage temperatures conveniently. The digital displays give you the heater levels and it’s easy to make your adjustments. The remote control feature helps you to regulate the garage climate while not physically present. The timers allow you to program the heating hours after which the heater powers itself off automatically.
  • Safety features : This being an electrical device, safety should be a top priority. A major hallmark of all electrical equipment should be recognition by global laboratories such as CSA, ETL, or UL. Besides certification, check for safety features that enhance safe operation. These may include but not limited to anti-tip protection, overheating protection, thermostat regulators, etc.
  • Electric Garage Heater Maintenance : After you’ve installed your heater, the next thing should be proper maintenance. It helps to keep you’re your unit working to the expectation and giving the best results. Below are some of the best options you can consider to keep your heater in excellent shape;
  • Dusting : In the process of working heaters tend to accumulate lots of dust particles. Convective heaters especially are the most notorious in dust harboring. The convectional air circulation brings in a lot of dust in the device. To remove these particles and maintain your heater in a health state, you should dust it at least once every week. Also, depending on where it’s used, even if you do more than once it’s still okay.
  • Remove grime : Just like dust, soot can greatly affect heater operations and lifespan. You can use a damp microfiber and dishwashing detergent to wipe the grime. Before wiping, make sure that the unit is completely powered off.
  • Vacuum : For effective air circulation, you need to vacuum your heater frequently. This is particularly important for garage heaters with fans, vents, and grilles. The process of vacuuming helps to clear the airflow effectively.
  • Wipe heat reflectors : Garage heaters that use shiny surfaces should be occasionally wiped off the dust to keep them clean. With time, these parts also accumulate dust and you should unscrew the grille and clean them with a towel.
  • Remove rust : With time, reflector surfaces catch rust especially if you don’t dust them frequently. In case you notice the presence of rust, use rust spray removers or scrubs to eliminate it. Something worth noting is that to undertake all these practices, you should turn it off and let it cool down.
