I purchased this heater for a bedroom that’s about 12x16 feet, but unfortunately, it couldn’t adequately heat the space. The heater's range is only about 2 to 3 feet, and if I set it to H2 or any temperature above 70°F, it would overheat and shut off after 15 to 30 minutes. This seems more suitable for a desk or cubicle, but it's not powerful enough to heat a full bedroom, despite what the listing suggests.
