Three best garage heaters

Kailey Fralick

For some, winter's approach means putting their DIY projects on hold until spring. It's simply too cold to be out in the garage or workshop. But with a garage heater, you're able to keep working all year round in comfort. There are dozens of models to choose from, but finding the right one for your garage isn't always easy. Here's a short guide to walk you through the most important considerations when choosing a garage heater, plus our three favorite garage heaters on the market.

Considerations when choosing garage heaters

Electric garage heaters come in two main types: fan-forced and infrared. Fan-forced heaters are the most common. They work by drawing air in, heating it up, and then blowing it back out again. Many people like these garage heaters because they're capable of warming up large spaces quickly. However, because they use a fan, they can blow dust or debris around, so you have to be careful where you point them.

Infrared heaters don't heat up the air at all. Instead, they heat up the objects they're pointed at. These garage heaters don't heat up as quickly as fan-forced models, but they do provide consistent, steady warmth, and you don't have to worry about a fan blowing dust or debris around.


Here are some other things you'll need to think about when choosing a garage heater.

Heating power

Some units are more powerful than others and more suited to heating up a large space. You can get a sense for how powerful a garage heater is by looking at its BTU rating. A higher BTU rating means more power. Consider the size of your garage, and make sure you choose a unit that can heat the entire space.

Wiring requirements

Garage heaters are more powerful than standard space heaters, and a regular outlet isn't enough for them. Some heaters can use a 240-volt outlet, but many must be hardwired. If you can't do this work yourself, hire a professional electrician.


Many garage heaters come with a mounting bracket. Some heaters are designed to be hung from the wall or the ceiling, while others can be mounted to either.

Temperature control

Some garage heaters only have a couple of settings like High or Low, while others let you choose the exact temperature that you want the garage to stay at.

Safety features

Look for a unit that has overheating protection to ensure that it won't start a fire. If you're not going to mount the garage heater, you should also look for one that has tip-over protection, which automatically shuts off the unit if it falls over.


Q. Are propane heaters safe to use in a garage?

A. They are safe when they are used correctly. Make sure you have good ventilation and always follow the manufacturer's instructions if you're going to use a propane heater. Electric garage heaters are generally considered safer, however, so one of these units may be a better fit if you don't want to worry.

Q. Does my garage heater need to be hardwired?

A. That depends on the model. Many garage heaters do need to be hardwired, but this isn't always ideal, especially if you want something portable. There are models that can use a 240-volt outlet, so look for one of these if you want maneuverability.
