The Comfort Zone Garage Heater is designed to efficiently heat large indoor spaces like a garage gym, with a substantial heating capacity of 10,000 watts. It uses electric power and requires a 240V connection, ensuring strong and reliable heating. The fan-forced air system and adjustable airflow vents help distribute heat evenly, eliminating cold spots and providing consistent warmth throughout a 1500 sq. ft. area. This makes it an excellent choice for those looking to maintain a comfortable workout environment in their garage gym during colder months.

The digital thermostat control and included remote offer convenient temperature adjustments, and the 12-hour timer adds to its energy efficiency. The heater is robustly built with a heavy-gauge steel body, making it durable and suitable for dusty environments. Safety features such as overheat protection, power, and caution indicator lights, and an overload switch enhance its safe usage.

However, it must be ceiling-mounted, which may require professional installation and isn't portable. Additionally, the heater is somewhat heavy at 42.2 pounds, so it isn’t designed to be moved frequently. Despite these limitations, its low noise level, efficient heating, and safety features make it a strong candidate for heating a garage gym. The unit's one-year warranty further suggests reliability and user satisfaction.

The Mr. Heater F260550 Big Maxx MHU50NG Natural Gas Unit Heater is a powerful option for heating a garage gym, with a 50,000 BTU per hour capacity that can warm up to 1250 sq. ft.

The heater's design allows for both vertical and horizontal venting, which can be convenient depending on your space layout. Additionally, it comes with a thermostat control that is easily accessible from the outside, making temperature adjustments straightforward. Safety is well-addressed with a high temperature safety shut-off switch, minimizing the risk of overheating. However, it requires an 8-foot minimum clearance from the floor, which might be a limitation for some garages.

Portability isn't its strong suit since it's a ceiling-mounted unit and weighs 66 pounds, making it more of a permanent fixture than a movable heater. The heater includes a limited 3-year warranty on parts and burners and a 10-year warranty on the heat exchanger, providing some long-term security. This heater is a robust, reliable choice for those who need a consistent and powerful heating solution for their garage gym, with the main drawback being its installation requirements.

The heater is also portable, with a compact 16-inch design and a hidden handle, making it easy to move around your space. However, it is important to note that it should not be used with an extension cord and must be plugged directly into a wall outlet for safety reasons. The noise level is impressively low at 40dB, which is as quiet as a library, making it suitable for environments where minimal noise is preferred.

The 70° oscillation feature ensures even heat distribution throughout the room, enhancing comfort. The included remote control provides convenient access to all settings from up to 26 feet away. While this heater is energy-efficient with its smart ECO mode, it may not be sufficient for very large spaces or extremely cold conditions.
