Things to Consider When Buying a Garage Wall Heater

There are four key considerations to make when buying wall heaters for garage; design and appearance, power rating, cost of running the heater, and the unit’s price.

  • Design and Appearance

The most crucial factor here is how well the item fits in with your existing decor. Although the garage isn’t all about looks, you still want a heating system that blends into the overall organization of the space.

Additionally, you may want to consider heaters made from heavy-duty steel, considering that the garage sees a bit of rough handling. A robust and sturdy build also means that you get to use the appliance for a prolonged period.

  • Power Rating

The amount of heating power you need will depend on several factors, including how cold it gets in your location and the size of your garage. Other essential factors are the quality of insulation in the garage.

If the area is poorly insulated, you’d need more power to compensate for the lost heat so you want to choose an energy-efficient garage heater.

That said, the best garage heaters are rated at 18,000+ BTU or 2 Kw+. An 18,000 BTU/2 Kw heater generates enough heat to keep a medium-sized garage warm throughout. Don’t forget to check the efficiency rating. Reliable efficiency starts at 95%.

  • Cost of Running the Heater

The cost of running a garage wall heater depends on three main things; the type of heater, power rating, and efficiency. Concerning the heating types and options typically include electric heating, infrared heating, and natural gas.

Electric wall heaters for garage with fans are the most expensive to run of the three. Infrared heaters, meanwhile, are the cheapest to run. The higher the power rating, the more costly it is to run the heater.

As for efficiency, strive for the highest rating possible. Low-efficiency heaters cost you more by converting only a small portion of the electric/gas power into useful heat.  

If you want to further reduce heating costs, you can use kerosene heaters for garage since they don’t require electricity.

  • Cost of the Unit

All the above factors will affect the cost of the product. Those charming designs and sturdy, long-lasting frames will add to the cost of the heater. The same applies to a higher power rating and great efficiency. In general, heaters that cost less to run are also likely to cost more upfront.

Regardless, the best wall heaters for the garage tend to be priced in the $150 to $250 range. We’d recommend that you shop in that range or consider these energy-efficient electric wall heaters.

Installing a Garage Wall Heater

For this section, we’ll only cover installation steps for electric heaters, which are the most popular garage wall heaters.

Electric wall heaters come in two styles: hardwired and corded models. Corded models are the easiest to install. All you have to do is find a space on your wall that would allow the heater to push out heat throughout the garage with minimal obstruction, install the supplied mounting bracket, screw the heater into the bracket, and plug it in.

We recommend installing it at the back wall of the garage such that it faces the door.

Hardwired models, meanwhile, are a little more demanding during installation. Once you’ve identified the right location and installed the mounting bracket, you’ll need to connect the unit to your home’s electrical system.

This is done by running a sheathed electrical cable from the heater (through the thermostat if you decide to install one) to the nearest circuit breaker.

Safety Tips When Using Wall-Mounted Garage Heaters

Compared to other types of heaters, wall heaters are generally safer. However, there are still a few safety precautions to observe especially since most of these are ventless heaters.

If you’re not aware there are a lot of dangers with ventless propane heaters that you need to be aware of and take the necessary precautions when using them.

  • Get the ventilation right 

This especially applies if you’re using a natural gas or propane heater. The heating process generates poisonous gases as byproducts. Proper garage ventilation protects those inside the garage by providing a way out of the room for the fumes.

  • Plug it directly into an outlet

For electric heaters, never plug them into an extension cord. Why? Because most extension cords can’t handle the amount of electric current that flows through to the heater, thus create an overheating and fire risk.

  • Eliminate any obstructions 

Having items close to or in the heater’s way creates a preventable burn and bump risk. So, clear the area around the heater. Items that can easily catch fire such as fabric and plastic should be especially kept at least three feet from the heater.
