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.

With a high heating capacity of 15,000 watts, it provides substantial heat output, making it suitable for large spaces.
