Direct fired models are the cheapest design to manufacture. The fuel is burned to generate heat and this heated air is pushed out the front of the unit by the built-in fan. The space heaters shown here without a fuel tank run on propane, the others run on a variety of liquid based fuels (such as diesel, kerosene, oil, paraffin etc).
