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.

The Heat Storm 1500 Watt Electric In-Wall Heater offers a flexible heating solution suitable for indoor spaces around 150 square feet, which could work well in smaller garages or rooms.

The built-in WiFi and digital thermostat make it easy to control temperature remotely and set custom schedules, which is a convenient feature not commonly found in garage heaters. Safety is addressed with overheat protection and a child lock, giving peace of mind if you have kids or pets around. The wall-mount design helps save floor space, though it means the unit is less portable than freestanding heaters.
