Ecodesign of Energy Using Products Directive (ED) and Energy Labelling Directive (ELD) are recent legal instruments in the European Union aiming to improve the energy efficiency of appliances. While energy labels assist consumers in choosing products which save energy, and thus money, ecodesign is aimed to eliminate the least efficient appliances from the market by establishing specific minimum requirements for specific product groups. The aim is that the ecodesign and the energy labelling requirements be introduced at the same time to facilitate implementation of the two measures and to guarantee the longest possible validity for the energy label. Energy labelling was addressed in REHVA Journal – March 2013 issue. In this article the new Regulation on ecodesign of heaters is presented.
