Heat Wagon Direct-Fired Heaters
Dual-Fueled Propane or Natural Gas Direct-Fired heaters by Heat Wagon. These powerful, efficient heaters are suitable for placing large volumes of heat into well-ventilated areas such as factories, bay doors, hangers, construction sites. Note that the air that heats is combusted air, with some remaining fumes. For more clean, breatheable air, opt for an indirect-fired heater, which is more like a home furnace, with the exhaust from the heating chamber vented through a stack, or chimney.
