This paper presents the analysis of efficiency improvements of home appliances such as Electrical Stove (Injera Mitad), Electrical Showers, Kerosene Stoves, Charcoal Stoves and Small Electrical Stoves for energy conservation. Most of the existing stoves have been manufactured by small facilities without any regard for energy efficiency standard and safety. It suffers from many shortfalls, such as, poor insulation, lack of temperature regulation, bulkiness and overall poor design that encourages wastage of heat. The energy efficiency of the ordinary electric stove is very low since much of the heat energy is lost through the bottom, its sides, on the top part of the oven and also due to the much delay in the existing Injera baking procedure. The overall efficiency of the electrical shower is affected by the reservoir efficiency and the characteristics of the pipe. Kerosene and charcoal stoves have high heat energy loss due to lack of insulation to their external cover. Therefore, the efficiency of those electrical home appliances can be improved by minimizing the losses through their covers and parts. This can be achieved by selecting appropriate low thermal conductivity materials and insulations.
