If you are looking to turn your garage or barn into a work space you can use all year-round, you will have to find a safe quiet and reliable heat source. This Mr. Heater 80,000 BTU Big Maxx Natural Gas Unit Heater is the way to go. The natural gas heater uses a built-in electric high-velocity fan to pull cool air into the rear of the unit, across a heat exchanger, then forcing warm air into the surrounding areas. These natural gas unit heaters only require 115V AC power and can be vented vertically or horizontally (please check local codes and restrictions). With a mounting clearance of only 1 in., supplied brackets, external access to power and thermostat connections, installation is a cinch. With the Durable Spark ignition and robust factory-standard self-diagnostic control module, we can offer a 3-year factory warranty on all parts and burners and a 10-year warranty on any defects in the heat exchanger. This heater offers the operating versatility and safety that you have come to expect from Mr. Heater.
