Determination of the Energy Efficiency of Domestic Electric Cooktops in Real Operating Conditions

Over the past years, energy efficiency has become a current issue of great concern in all sphere of industry and household sector. This paper presents a methodology for assessment of the energy efficiency of household electric cooktops, while taking into account the impact of various operating factors and measures to improve it. The results obtained and the conclusions drawn show that the use of modern domestic hobs improves energy efficiency. The development of adequate models for evaluation of the influence of the exploitation and design factors on the energy efficiency of electric hot plates (EHP) will enable the achievement, with ecodesign of these appliances, of maxumum boundary values of energy consumption in energy-related products, as set in the draft of the EU Regulation for implementation of Directive 2009/125/EC, and will also ensure that adequate measures are taken to improve the energy-efficiency services in this sector as per BS EN 15900.
