    Benefits of Garage Heaters

    • Be more comfortable. If you do a lot of work in your garage or workshop in the winter, then you want to be as comfortable as possible. The best garage space heaters heat up the area so your body and hands stay warm, making work easier to do.
    • Protect your vehicle. Your vehicle warms up faster in a heated garage. It's easier to start, the oil is less viscous, and the coolant is warmer, even if the temperature is really cold outside.
    • Free up space in the house. If you heat up your garage, you can use it for activities that you would normally do in your home. For example, you can create a TV room or a playroom for your children.

    Types of Garage Heaters

    Fan-Forced 

    Fan-forced heaters have integrated fans and are one of the most common types of garage heaters. They are easy to install and convert electricity into heat. The fan sucks in cold air, warms it up, and then blows it out over a heating element. The best thing about these heaters is they generate a lot of heat and work quickly.

    Radiant/Infrared 

    Some of the best heaters for uninsulated garages are radiant/infrared heaters. They direct heat towards nearby objects. The heat they generate is more comfortable than fan-forced heaters. However, in order for you to feel the heat, you need to be rather close to the unit. That's why these heaters are not quite as popular as fan-forced heaters.

    Propane, Kerosene, and Other Fuels

    The best propane heaters for garages use fuel instead of electricity to warm a garage. Since they don't require electricity, they heat up very quickly. They are also very portable, so you can buy one unit and carry it from your garage to your workshop, for example. They are ideal for large areas but can be dangerous in enclosed spaces.

    Fixed vs. Portable

    If you want a heater that you can move around within your garage or to other places in your home, a portable heater is a good option. These heaters are usually lightweight and are operated using fuel or electricity. Conversely, fixed heaters are wired into your home's electrical system and are often mounted on the wall or ceiling. You don't have to worry about knocking it over, and it provides more space if it’s mounted higher up on the wall or ceiling.

    Garage Heaters Pricing

    • Under $100: Several fan-forced and propane-powered heaters are available at an affordable price. They work well on job sites, in garages, and in workshops. However, they won't be as powerful as some larger, more expensive options.
    • Around $200: More effective heaters are available at this price point. They may be powered by either gas or electricity and are designed to pump out a lot of heat.
    • Over $200: Commercial and industrial heaters can cost several hundred dollars, such as this Modine Natural Gas Hot Dawg Garage Heater, which has 45,000 BTUs.

    Key Features

    Safety 

    The best heaters for garages have several safety features, such as a tip-over switch, overheat protection, and a cool-to-the-touch surface area. If you have a stand-alone heater, it may accidentally get knocked over, so a tip-over switch will automatically turn it off. 

    If the heater stays on for a long period of time, overheat protection will ensure it turns off if the temperature gets too high. Cool-touch heaters are important if you have pets or children near the unit because you don't want them to hurt themselves if they touch it.

    Power Output

    Different heaters generate different BTUs. Smaller gas ones generate from 4,000 to 9,000 BTUs and are adequate for spaces up to 250 square feet. Two-car garages are typically 500-600 square feet and may require a heater with 25,000 BTUs. If you're using an electric heater, look for one that is 2,500-5,000 watts for garages that are 500-600 square feet.

    Settings

    Ideally, the heater you choose will permit you to adjust the level of heat in your garage or workshop. Most heaters have both high and low settings or a thermostat that lets you change the temperature. When the mercury drops and it's really cold outside, you can use a higher setting, while if it's just a spring chill in the air you can use a lower setting.

    Other Considerations

    • Accessories: If you're shopping for a portable garage heater, then look for one that has a carrying handle. This allows you to transport it more easily. Another convenient option is wheels and castors. You can roll the unit around instead of lifting it up, which can be better for your back.
    • Power Cord Length: If you're using an electric garage heater, think about where you need to use it and whether or not it's near a plug. It can be dangerous to use extension cords with high-power output heaters, so you need to find one that has a power cord that's long enough to reach the plug.

    Tips

    • Many garage heaters will not work with a home's standard 110- or 120-volt outlets; they require 240-volt outlets. So, you may need a professional to upgrade your electrical system so it can accommodate larger garage heaters.
    • Some types of garage heaters use a fan in conjunction with the heating element, which can blow dust into the air. Be sure to position it properly if you're painting or working on other tasks that need to be dust-free.
    • A garage heater around 1,500 watts will work well in smaller garages that are less than 150 square feet. Heaters around 2,500 watts are good for medium-sized garages up to 250 square feet, while heaters with 4,000-5,000 watts are recommended for large garages that are up to 500 square feet.

    FAQs

    Q: Are garage heaters safe?

    A: Many features overheat protection that turns the unit off if it gets too hot. Look for those that include a tip-over switch that turns the unit off if the heater gets knocked over. Finally, some models are cool to the touch to prevent burns.

    Q: Do I need to clean my garage heater? 

    A: Some heaters require less maintenance than others, but most need to be cleaned occasionally. The most durable garage heaters are solidly constructed, include a self-lubricating fan motor, and feature an air intake grille that filters out debris.

    Q: Will a heater work in an uninsulated garage?

    A: Without insulation, your garage loses a lot of heat. To get the best performance out of your garage heater, make sure the walls and doors are insulated, as well as any cracks, outlets, and light switches.
