10 Best 120 V Garage Heater 2025 in the United States

The DR. INFRARED HEATER DR-PS11524 is a powerful garage heater designed for construction and industrial use. With a high heating capacity of 15,000 watts, it provides substantial heat output, making it suitable for large spaces. The heater requires a 240-volt single phase power supply and an 80-amp circuit breaker, which might be challenging for some users to install, as it needs hardwiring.

This heater stands out for its clean, instant, and odor-free heat, ensuring a pleasant environment in the garage or workspace. Safety is well addressed with heavy-duty steel framing and safety guards on both the intake and output ends, enhancing its reliability. The adjustable thermostat allows you to control the temperature within a range of 37 - 104°F, giving flexibility to maintain the desired warmth level easily.

One of the notable features is its portability, thanks to the included cart and wheels, making it easy to move around as needed. However, at 70 pounds, it is relatively heavy, which could be a drawback for some users. While it is not very quiet, the noise level is typical for units of this power. The heater is designed for floor mounting and has a durable build, but assembly is required. It also comes with a 1-year limited warranty on parts and components. This heater is a solid choice for those needing a high-capacity, durable, and portable heating solution for large indoor spaces, provided they can accommodate its installation requirements.

The Heat Storm HS-1500-PHX-WIFI Infrared Heater offers great features for those looking to heat a garage. With 1500 watts of power and a heating capacity of 5200 BTUs, it can serve as a primary heat source for smaller spaces up to 150 sq. ft. or as supplementary heat for larger areas up to 750 sq. ft. Its wall-mounted design saves floor space, making it ideal for tight areas like garages, bedrooms, or offices. One of the standout features is its Wi-Fi capability, allowing you to control the temperature from your phone, adding a layer of convenience.

Safety is well-addressed with a tip-over safety shut-off and a grill that remains cool to the touch. The heater is also designed to keep the wall cool, preventing any potential damage to your home’s structure. On the downside, it may not be the best option for very large garages or poorly insulated spaces, as its primary heating capacity maxes out at 150 sq. ft. Additionally, it does not come with feet, limiting its portability since it's designed strictly for wall mounting. Infrared heaters are generally quieter than fan-based models.

If you're looking for an efficient, space-saving, and smart-controlled heating solution for a small to medium-sized garage, this unit could be a good fit.

The COSENG Outdoor Heater offers fast and efficient heating with its 1500W power and instant infrared technology that starts warming up in just 3 seconds. This makes it a solid choice for garage use, patios, or other outdoor spaces where quick, reliable heat is needed. It has four heat levels and a 24-hour timer, plus a memory function that remembers your settings, so you don’t have to adjust it every time you turn it on. The digital touchscreen is user-friendly and adds convenience.

Safety-wise, it carries an IP65 waterproof rating, meaning it’s protected against rain and dust, making it suitable for outdoor or semi-outdoor use even in damp conditions. The heater is designed for wall or ceiling mounting, saving floor space, but it’s not the most portable option if you want to move it around frequently. Infrared heaters generally operate quietly, which is a plus for garage or indoor use. The maximum temperature reaches about 100°F, enough for mild to moderate warming needs but not for very cold spaces.

It runs on standard 120V power, compatible with most home outlets. One limitation is the wattage—1500W is decent for small to medium areas but might struggle in larger or poorly insulated garages. Customer reviews are very positive, reflecting satisfaction with its performance and durability. The 1-year warranty and responsive customer service add confidence in the purchase. This heater is a good pick if you want a quick, safe, and energy-efficient heat source mainly for smaller indoor or outdoor spots, but it may not replace bigger, more powerful garage heaters for very chilly conditions.
