Buying Guide

1. Portability 

Portability also implies that it could be easily moved from one location to another without needing any professional help or specific tools. When you want to move a portable garage heater, look for one that is lightweight- below 10 pounds, preferably. It’s not supposed to be attached to the wall and doesn’t require any prior installation. If you’re on a tight budget and want to save money, look for one that has wheels.

2. Infrared or Fan Forced?

Infrared heaters have been around for decades as a way to heat small areas. They can be focused, so you only get heat where you want it, making them ideal for individual desks or corners of a room that need extra warmth. They use less power than conventional electric fans and do not blow hot air around the room, making them safer to use due to the lack of excess warm air.

On the other hand, many people choose to purchase a forced-air heater because it quickly heats up their room. This type of heater is usually placed in one corner of the room and set to a high fan speed. The high output fan blows air that has been warmed by metal or ceramic heating elements directly at you and your furnishing. Forced-air heaters can be noisy and are typically used in smaller rooms because of their limited reach. So, make a choice based on your priorities!

3. BTU Output

The amount of heat needed to heat a given space is based primarily on two factors: the square footage of the working area and the efficiency of your insulation. Here’s how to get the right size heater for your needs. 

  • Step 1: Measure the volume of your garage by multiplying the area in square feet by height.
  • Step 2: Multiply the volume by a number based on your level of insulation- 4 if it’s poor, 3 with medium efficiency, and 2 with excellent insulation.

For example, an area that’s 10 feet by 12 feet with an 8-foot ceiling needs about 160 square feet of floor space. If it’s poorly insulated, you need to deliver 3840 BTUs to heat it (10x12x8x4). If it’s well insulated, you’d need only 1920 BTUs (10x12x8x2).

4. Safety Features 

We take power for granted. It’s a feature that we expect at all times and don’t think much about it. However, a severe house fire caused by a faulty heating device is no laughing matter.  If you’re thinking about purchasing a space heater to heat your indoor spaces, there are some essential safety features to consider. 

These include automatic shutoff when they overheat, adjustable thermostat, flame failure device (a temperature-controlled device that shuts off the unit in the event of a fire), and tip-over protection (a feature that automatically shuts the unit off if it is accidentally knocked over). 

5. Adjustable Temperature

One of the biggest reasons people tend to avoid getting a heater for their garage is the inconsistency in temperature. If you’re trying to work on your car, for example, you want to be able to know what temperature your garage is at. 

When it comes to your Garage Heater, even the best will seem counterproductive if it doesn’t have an adjustable temperature. There are times when you’re sweating over your car in your garage and you think that a house with the air conditioner on would be so much better. In this case, an adjustable temperature garage heater would come in extremely handy.
