How To Choose The Best Heater For Uninsulated Garage?

Types

For your garage, there are four best types of heaters for you to choose from.

  • Wall-mounted infrared heaters: this is probably the best option for your uninsulated garage. A wall-mounted helps distribute the heat the most effectively. However, it costs more than the other type.
  • Tower heaters: you just need to plug the heat in and it will start heating the entire garage and they are cheaper. But this type is not suitable for garages with big workbenches and other big items because they will block the heat.
  • Propane convection heaters: heaters of this type are small but release heat in all directions so you should put them in the middle of the garage. But it’s only suitable for 1-2 car garages.
  • Propane forced-air heaters: instead of all directions, this type of heater releases heat in a certain direction. It’s suitable for over 3-car garages.

Size

As a rule of thumb, a small heater produces less heat and works better for a small garage. Therefore, when choosing a heater, you need to consider if it’s big enough for your garage.

Regarding this factor, you must consider the power rating, which is indicated in BTUs. This rating shows you the maximum heat amount produced by the heater.

You will also need to consider the size of your garage when choosing a power output so that you will have enough heat to warm up the entire garage without overdoing anything.

Safety features

  • Overheated protection: this feature will shut down the heater automatically if the temperature surpasses the set limit.
  • Tip-over switch: it will shut down the heater automatically if the heater tips over. This feature is common among oil-filled heaters.
  • Cool to touch feature: this feature helps you avoid burns if you accidentally touch the heater’s exterior.
  • Fan system: when the heater produces excess heat, this system will blow it away.
  • Inbuilt thermostat system: this feature controls how much energy the heater uses.
