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 250,000 BTU Natural Gas Unit heater is the way to go.
It uses a built-in electric high velocity fan to pull cool air into the rear of the heater, across a heat exchanger, then forcing warm air into the surrounding areas.
These 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 inch, the 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 Heatstar.
