DESCRIPTION: An enormous quantity of cooking gas as well as heat in stoves and 'angeethi’ is wasted during cooking due to improper heat-management. This heat-loss is unavoidable, irrespective of the high thermal-efficiency of the stove. Hence, heat shield around stoves, burners or angeethis enhances the thermal efficiency by 20-25%. It prevents the heat-loss due to the direct contact between the hot pot and relatively cold air. Once the air between the heat shield and the container is heated, it acts like a heat-jacket. Hence, there is maximum utilisation of cooking energy and minimum wastage of gas and fuel.
