This tent heater includes a 170kbtu heater, a 12″ x 12′ long duct hose, thermostat, and a full 100 lb. propane tank. This heater is meant to heat almost any fully inclosed area up to 600 square feet in total area. The heater itself and the propane tank must always be used outdoors with the heat being vented thru the duct hose into your area needing heat. The thermostat is hung inside your area to maintain the heat level you prefer. You will need a standard 110v power supply to run the blower on the heater.
