10 Best Garage Heaters 2025 in the United States

The Dr Infrared Heater DR-238 is a versatile heater ideal for both indoor and outdoor spaces, making it a great choice for garages, patios, and even restaurants. With a heating capacity of up to 1500W and three power settings, it provides clean, instant, and odorless infrared heat, which can be particularly appealing for those who dislike the smell of traditional heating methods. Its IP55 rating means it’s weatherproof, allowing for outdoor use without worry. It also comes with a remote control for convenient operation and includes wall and ceiling mounting brackets for easy installation, enhancing its portability.

A notable strength of the DR-238 is its efficient design, featuring a high-level mirror aluminum reflector that maximizes heat distribution, ensuring that even larger areas can benefit from warmth. Additionally, the heater is lightweight at just 8 pounds, making it easy to mount or move as needed.

There are a few drawbacks to consider. The heater requires assembly and might not be suitable for very large garage spaces if you need an intense heat output. While the ability to mount it on walls or ceilings is a plus, some users may find the 120V power source limits its effectiveness in larger, open areas without adequate electrical supply. Furthermore, the warranty is limited to one year, which may not provide peace of mind for long-term use.

The Mr. Heater F260560 Big Maxx MHU80NG is a solid choice for anyone looking to heat a garage or large indoor space, capable of delivering a strong heating capacity of 80,000 BTUs and covering an area of up to 2,667 square feet. Its natural gas power source is convenient for those with existing gas lines, and it comes with a conversion kit for liquid propane, enhancing its flexibility.

One of the standout features is its powered exhaust system, which allows for both vertical and horizontal venting. This versatility in installation means it can be adapted to various garage layouts. The heater also includes a spark ignition and a self-diagnostic control module, which contribute to its reliability and ease of use. Safety is prioritized with features like a high-temperature safety shut-off, making it suitable for long-term operation.

The heater does require some assembly and proper clearance from the floor, which might not be ideal for every garage setup. Additionally, the thermostat is not included, so you would need to purchase that separately to control the temperature effectively. Weighing in at 88 pounds, it’s not the most portable option, and if you’re looking for something easy to move around, this might not be the best fit. If you want a powerful heater and have access to natural gas, the Mr. Heater Big Maxx offers reliable performance, but be prepared for installation considerations and potential additional costs for a thermostat.

The Comfort Zone Garage Heater is an efficient ceiling-mounted electric heater designed for indoor use in spaces like garages and workshops. With a heating capacity of 5,000 watts and 240 volts, it can effectively cover areas up to 1,000 square feet. The fan-forced type ensures that heat is evenly distributed throughout the room, and the adjustable louvers allow you to direct the heat where it's needed most. This heater is made from heavy-gauge steel, making it durable and suitable for challenging environments.

Safety features include overheat protection and a power indicator light, providing peace of mind during use. The dual knob thermostat allows for easy temperature adjustments, ensuring a comfortable environment. Installation may require professional assistance, especially if you are not familiar with hard-wired electrical setups. Additionally, while the ceiling mount saves floor space, it can limit placement options if your ceiling is already crowded with other fixtures.

The heater provides three heat settings, but it lacks a remote control, which means manual adjustments are needed. It has been rated well for its performance and ease of use, with a solid 4.3 out of 5 stars from over 6,600 reviews. This heater is ideal for those looking for a robust and reliable option to keep their garages or workshops warm.
