How does it work?

A heater is only as good as the warmth it produces. The Big Maxx kicks out 50,000 BTU of heat per hour. It does this by pulling cool air into the rear of the unit, across a heat exchanger, and then forces the warm air into your work area. The thermostat dictates the temperature it releases the heat into your work area, always giving you the temperature you desire for your garage or barn.
