Buying Guide For Garage Heaters in 2021

A garage heater is an invaluable investment for your garage. Several heaters on the market may prove to be a great fit in your home, depending on the size of your garage and what type of fuel you’d like to use. So, read through the paragraphs below to learn a few tips and considerations before selecting a heater for yourself.

1. Type of Heater- Fan-Forced or Infrared?

The type of garage heater you choose has a lot to do with the amount of money you want to spend, the space available, and which features are best for your situation.

Fan-forced and forced-air heaters blow hot air in all directions. The amount of heat is not as concentrated, but they are much easier to operate. Infrared and radiant heaters have a very focused source of warmth but are more challenging to use since you must aim the heater at the area that needs heat. They’re not very efficient at heating a vast space but work without much noise and movement of air.

2. Required Power Input and Heat Output

The amount of heat that a heater will put out is measured in watts or BTUs. The higher the wattage or BTUs, the more energy it will use and the warmer it will make the room. Plus, the colder the temperature and the larger the garage, the higher the energy it will require to work. If it’s a small garage built for only one car, one with 2,000-4,000 wattage should be able to do the job. A bigger garage will require 5,000-10,000 wattage. 

Select the product with the heating capacity you need. And remember, a higher wattage rating generates more heat, but it also draws more electricity and limits your budget.

3. Size, Weight, and Dimensions

Portable Garage Heaters are usually lightweight and small in size, and as an added feature, they can be simply moved from one location to another. They do not require installation or fuel supply as they are plugged into the wall. On average, they weigh between 5-10 lbs. Plus, the small size means that they won’t get in the way of you working! If you want to move it from room to room, don’t look for one that needs to be attached or installed against a wall. Wheels could be the cherry on top for portability!

4. Safety Features

There are some essential safety features you should look for when buying a space heater. Some standard safety features include tip-over protection, shutoff protection, and auto-shutoff when it heats up-to prevent overheating. 

A tip-over sensor will automatically shut off if the heater falls over. This feature is essential because space heaters are often knocked over, and the tip-over sensor can prevent fires from starting. Many models will also automatically shut off if the unit overheats due to excessive use, reducing the risk of fires. Lastly, try to avoid purchasing one close to or taller than five feet, the size of most children. These models are dangerous because they may fall over and cause a fire or burn your child if he or she touches it. 

5. Adjustable Temperature

Adjustable temperature allows more precise heat control with garage heaters, allowing you to set the exact temperature in your garage based on the season, the place you live in, or what you’re using the garage for. It’s incredibly convenient in areas where temperatures are constantly fluctuating and if you’re moving from garage to garage. 

Final Verdict: Which Garage Heater is the Best for You?

For heating your garage, what’s best for you depends on what features are most important. Garage heaters have come a long way. There are many different models and styles to choose from, so which one is right for you? Are you interested in a forced-air heater, or are you leaning towards infrared? Safety is critical to most people, so make sure your garage heater can keep you and your family safe. So, what are your heating essentials?

We hope this article about the top 9 Garage Heaters in 2021 have helped you know the features and specifications of the topmost branded heaters and made your decision easier.
