The new design arrived at, is for semi-urban use. Air gap between the outside absestos insulation and fire pot in introduced which acts as a ligh weight insulator and also supplies hot air. The fire pot, has several holes to supply air evenly throught out the coal to avoid smoke formation. The ashes can be cleaned easily as the whole bottom plate is hinged on one side. The two ducts help in getting controlled burning. The height of the 'chula' is kept low to increase stabliity. The unit can be made by a small industry with very little skills.
