Best Garage Heaters – Buying Guide 

What should you look for when you start shopping for the best garage heaters? They’re not all equal and they can get expensive, so you want to get it right on the first try. Below, we’ll outline the biggest buying points you want to consider when you shop. 

Garage Heater 2 Guide
Anyone who has a smaller garage can get away with installing and using a smaller heater, but high ceilings and larger garages need more power to keep the temperature up. 

Power Rating

One of the most important aspects of your garage heater is the power rating. If you get one powerful enough, you could use it to heat your garage all year round or heat your porch when you finish building it. Many brands list the heater’s power rating right on the box, and they’ll usually give you an approximate square footage it’ll cover. However, the power rating assumes you have the best conditions possible, so pick out the best garage heater that has a slightly higher power rating than you need. 

Getting a slightly higher power rating covers you if you have drafts or poor insulation in your garage. The ceiling height is something else to remember because taller ceilings give the room more space to circulate the heat, and this means your heater will have to work harder. Generally speaking, a larger garage will need at least 4,000 to 5,000 watts to fully heat it. 

Safety Features

When you work in your garage, keeping yourself and anyone else in there safe is a top priority. There are dozens of safety features available on the best garage heaters that work well. If you have a shutoff switch, it’ll turn the heater off if it accidentally falls over to prevent a fire. Some heaters have overheating protection built right into the design that shuts the heater off if it gets too hot. This protects the internal workings too. 

For maximum safety features, get a heater that has a cool touch design. This prevents the exterior from heating up when it runs, and it’s a great way to prevent burns if you have animals or kids in the vicinity. If your kids had a sleepover and came out to the garage to talk, this will help keep them safe. Check for any certifications or accreditations with your heater, and take a few minutes to go through reviews and see what they say. 

Garage Heater 3 Safety
Keeping your family and kids safe is your top priority, so you never want to run a gas-powered heater in an enclosed space because the fumes can reach toxic levels. 

Heater Type

There are a few different heaters you can choose from when you pick out the best garage heater. Fan forced heaters come with an integrated fan that you can adjust. They produce a lot of heat, and they work well to quickly warm up a medium or small-sized garage. Infrared or radiant heaters are next. They produce more comfortable heat, but they’re not really powerful. You have to have them very close to you or have a small space to heat. 

Finally, the third type of best garage heater uses natural gas, diesel, or propane to run. They don’t need electricity to run, and they can heat a space very quickly. However, you don’t want to use them in an enclosed area because they produce fumes, and this can be dangerous to breathe in. All of these heaters come in portable or fixed designs. 

Ease of Installation and Assembly

You can get a heater that comes assembled and ready to use straight out of the box, and others require that you put them together before you use them. If you like to DIY, putting the best garage heater together may not be a problem for you. If it is, look for a pre-assembled one. Other types of heaters require that you hardwire them into your existing electrical connections, and this is a job best left for the professionals. 

Adjustable Features 

Do you need your best garage heater to adjust the temperature or is one steady one okay? Maybe you’re in the process of pricing out how much it would be to replace the windows in your garage, so you have drafts. Or, you could want to move the heater from the garage to your home. If so, having an adjustable temperature control would be nice. This prevents you from switching it on and off as you get too hot. Some heaters also come with a remote control, and this adds a layer of convenience to it. 

Garage Heater 4 Gauge
Being able to adjust the temperature on your best garage heater ensures that it doesn’t get too hot or too cold as you work. 

Length of the Power Cord 

If your best garage heater plugs in, check the power cord length. You want it to be long enough that you can reach all over in your garage without having to unplug it and plug it back in a thousand times. Six feet is a very common length, but this isn’t long enough for larger garages without an extension cord. If you have a high-output heater, finding a safe extension cord can be challenging, so go for a longer cord in general to save yourself the hassle. 


Do you intend to keep your heater in one place or move it around? If you want to move it, portability is going to be a big issue to pay attention too. If you get one with a carrying handle, it’ll make moving it that much easier. Casters and wheels help too if you choose a larger industrial heater. It all comes down to whether you want a portable garage heater or a fixed one. Decide what you’re going to use the heater for most and go from there to make a solid choice. 

Garage Heater 5 End
The right heater gives you the flexibility to work on your projects in your garage all year round, no matter what the temperature and weather is doing.

Bottom Line 

The best garage heater will change depending on the size of your space and how often you have to use it. Before you start shopping for your best garage heater, look at our short reviews. They allow you to compare several high-quality options before you buy, and our guide can help you understand what features you want to consider.
