The Aura Comfort Plus heater brings heat and warmth to up to 64 sq. ft. of your favorite outdoor area. The Comfort Plus heater is extremely efficient, converting up to 90% of the energy used into directional, radiant heat. The Comfort Plus uses infrared technology to heat people and not the air, creating a virtually wind-proof heat that won't be blown away by a breeze. The Comfort Plus heater is built to be weatherproof, allowing it to be left outside regardless of weather conditions. The heating unit is mounted on top of a durable, portable stainless steel post with a weighted base. The On/Off switch is conveniently located on the post of the heater, with a built-in tip safety to automatically cut the power supply if the heater is knocked over.
