Mr. Heater 80,000 BTU Ceiling Mounted Air Heater

The Mr. Heater Big Maxx 80,000 BTU forced-air unit heater is designed to transform your workspace into a comfortably heated area suitable for year-round use. It utilises a high-velocity electric fan that draws cool air over the heat exchanger, producing consistently warm air. The heater’s low-profile design mandates only a 10 ft minimum ceiling height, requiring just 1 inch of mounting clearance for installation. Key safety features include a high-temperature shut-off switch, a gas safety shut-off flame sensor, and an electric spark ignition with a self-diagnostic control module. Additionally, the unit operates on natural gas and comes with a conversion kit for propane use, along with a thermostat and ceiling mounting brackets. The heater requires a 115-Volt AC power connection and can be vented either vertically or horizontally, depending on local codes and restrictions. This model provides the versatility and safety features expected of Mr. Heater products.
