Shopping for the best garage heater for your space

Whether you use your garage to tinker with your vehicle or use power tools for home improvement projects, it can be disappointing to lose your favorite workspace when winter sets in and it becomes too cold to use. To keep your garage comfortable through chilly seasons, you need to invest in the right garage space heater.

Shop this article: Comfort Zone 5000-Watt Heater, Comfort Zone Portable Utility Heater and Stanley Heavy-Duty Space Heater.

Stationary vs. portable garage heaters

The first thing you need to determine when buying a garage heater is whether you want it to be a permanent fixture in your garage or a portable appliance with more flexibility. 

  • Stationary heaters are mounted to the wall or ceiling and offer a more commercial, finished look. They are generally higher in quality than portable ones but require careful installation to ensure safety.
  • Portable heaters are smaller, more affordable and available in a wider range of configurations. They have handles that let you move them around your garage, store them out of sight when not needed or load them into your vehicle for use on a job site.

Types of garage heaters

Garage heaters have an electric or gas fuel source, and there are a variety of types to consider.

  • Propane and natural gas heaters provide extreme heat. A gas space heater is ideal for especially large spaces, but good ventilation is required because it creates fumes that can be irritating or harmful to breathe in.
  • Convection heaters use a fan to blow air over heated coils and distribute it throughout the room. Some convection heaters have oscillation options that help circulate air more effectively. These heaters are great for warming entire spaces without having to worry about flammable gas.
  • Radiant heaters warm the area in front of them using a heated coil or ceramic element. They don’t use a fan, so they won’t dry the air out like convection heaters. Because they are not great for heating an entire room, radiant options are best used when you will be spending most of your time in one place, such as at a desk or workbench

Heater power

For best results, get a space heater for garage spaces that is powerful enough to warm the entire room without using too much fuel or energy.

The power of an electric heater is measured in watts. You can easily determine how many watts you need by multiplying the area of your garage by 10. For example, a 1,000-watt heater should be able to efficiently heat a 100-square-foot room. 

Heaters that burn gas have their power measured in British thermal units, or Btu. It’s a bit more complicated to calculate how many Btu you need to heat your garage, but most heaters have information on their packaging regarding how large a space they can warm.
