10 Best Electric Garage Heaters 2025 in the United States

The Heat Storm HS-1500-PHX-WIFI Infrared Heater is a wall-mounted, Wi-Fi-enabled electric garage heater offering 1500 watts of power and 5200 BTUs of heating capacity. This heater is suitable for small spaces, effectively heating up to 150 square feet as a primary source and up to 750 square feet as a supplemental source, depending on insulation. The built-in Wi-Fi feature allows for convenient control of the heater's temperature through a smartphone, adding a layer of modern convenience. Safety is well-addressed with features like a tip-over safety shut-off and a cool-to-the-touch grill.

The digital thermostat and remote control provide ease of use, and the space-saving wall mount design is ideal for areas with limited floor space. However, the heater does not come with feet, so it must be wall-mounted, which might limit its portability. With a noise level that is generally low, it is suitable for environments like bedrooms, offices, kitchens, and small garages. On the downside, with a heating coverage of only 150 square feet as a primary source, it may not be powerful enough for larger garages or more substantial heating needs.

The heater's weight of 9 pounds makes it relatively easy to install, but it does require a 110-volt power source. With a 4.4 out of 5-star rating from over 17,000 customer reviews, it is a well-regarded option for those needing a compact, efficient heating solution for smaller spaces.

The KING KB2410-1-ECO2S-PLUS is a solid choice for heating a garage, providing a strong 10,000-watt (10kW) heating capacity powered by 240 volts, which means it can warm medium to larger spaces effectively. Its 2-stage heating feature is smart—it automatically adjusts to use the lowest wattage needed, helping save energy and potentially lowering your electric bill. This model comes with a remote temperature sensor, allowing you to control the temperature more accurately from a distance. It also supports connection to popular smart thermostats like Nest, adding convenience if you want to manage your garage heat remotely via your phone.

The heater is designed for ceiling mounting, which frees up floor space and keeps it out of the way. Though it’s electric and radiator-based, it operates quietly, which is a plus for indoor use. The unit is not meant to be portable since it mounts to the ceiling and weighs a moderate amount. This product is best suited for homeowners who want a reliable, energy-conscious garage heater with remote control functionality, rather than those needing a lightweight or easily moved option.

Combining effective heating with smart controls, this heater is well-suited for indoor garage environments where consistent heat and energy savings matter.

The Dyna-Glo Dual Power 15,000W Electric Garage Heater is designed for heating spaces up to about 1,000 square feet, making it a solid choice for typical garages or workshops. It offers two power settings: a lower 11,300W mode and a higher 15,000W mode, providing flexibility depending on how much heat you need and your electricity usage. The heater runs on a 240-volt power source and has 24 adjustable heat settings, allowing you to set temperatures between 50°F and 95°F. This level of control is convenient for maintaining a comfortable environment without overheating.

One standout feature is that it can operate as a fan without heat, which can be useful during warmer months. The adjustable angles with a safety lock let you direct airflow horizontally or vertically, improving comfort and efficiency. Safety is addressed with overheat protection to prevent accidents. It includes a remote control for easy operation, which adds convenience, especially if the unit is mounted or placed out of direct reach.

The unit is fairly heavy at 56.6 pounds and designed mainly for floor mounting, so it isn’t very portable if you need to move it frequently. Electric radiant heaters like this typically operate quietly or with minimal sound. This heater represents a practical option for someone looking to effectively heat a medium-sized garage or workspace with reliable temperature control and safety features, although it might not be the best choice if you require a lightweight or easily movable unit.
