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 Dreo Space Heater is a versatile and efficient option for a garage gym, offering a powerful 1500W PTC ceramic heating element that can quickly warm spaces up to 200 sq.ft.

Additionally, it has an adjustable thermostat ranging from 41 to 95°F, allowing precise temperature control to suit your needs.

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. The Dreo Space Heater is a reliable and user-friendly choice for maintaining a comfortable temperature in your garage gym. Its combination of heating efficiency, safety features, and quiet operation make it a strong contender in its category.

The Mr Heater 4000 to 18000 BTU Portable LP Gas Heater is a solid option for heating spaces like garages or gyms, offering versatile heating levels with a range between 4,000 to 18,000 BTUs, which is suitable for areas up to 450 square feet. Its propane power source is convenient for both indoor and outdoor use, making it adaptable for various settings, from a home workspace to outdoor activities. Portability is a key strength, as it weighs only 15 pounds, allowing for easy relocation depending on your heating needs.

Safety is a highlighted feature with automatic shutoff systems in case of tip-over, complemented by a low-oxygen shutoff function. This ensures peace of mind while using it in enclosed spaces, although proper ventilation is still recommended. The simple single control start knob and reliable piezo ignition make it user-friendly, especially for those not tech savvy.

There are a few drawbacks to consider. The heater requires additional accessories like hoses and filters for propane tanks which might not be included in your purchase. This could be an inconvenience for users who expect a plug-and-play solution. Additionally, while it performs well in terms of heating, it may produce some noise, which could be distracting if used in a quiet environment.
