Experimental study of energy efficiency of kitchen electrical appliances for boiling water

Introduction. Steady growth in the number of powerful electrical appliances and devices in households leads to an increase in electricity consumption. It significantly affects the economic costs of consumers and the deterioration of the ecological situation in the environment. Problem. The cost of electricity tariffs for the population tends to be relatively steadily increasing, which makes the issue of energy efficiency particularly relevant for consumers. The use of energy-efficient technologies in everyday life allows reducing electricity costs and increasing the economic efficiency of households. Energy efficiency of household electrical appliances is a pressing issue for ensuring a stable energy supply in the context of growing electricity consumption. Goal. An analytical study of the operating features of kitchen electrical appliances for boiling water and an experimental study of their energy efficiency. Methodology. The energy efficiency of the most common kitchen electrical appliances for boiling water was analyzed through experimental studies. Results. In terms of energy efficiency, the flow-through thermopot turned out to be the best among the studied electrical appliances, followed by an electric kettle and a traditional thermopot. Practical value. The use of energy-efficient technologies in modern household appliances is an important task, especially in winter and in conditions of shortage of electric power during military aggression from Russia and large-scale destruction of critical infrastructure and power facilities in our country. Further research will help reduce energy consumption and increase the energy efficiency of household appliances.
