L 239162 Official Journal of the European Union 6.9.2013 COMMISSION REGULATION (EU) No 814/2013 of 2 August 2013 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for water heaters and hot water storage tanks (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Directive 2009/125/EC of the European Parliament and of the Council of 21 October 2009 establishing a framework for the setting of ecodesign requirements for energy-related products (') and in particular Article 15(1) thereof, After consulting the Ecodesign Consultation Forum, Whereas: Under Directive 2009/125/EC ecodesign requirements should be set by the Commission for energy-related products representing significant volumes of sales and trade, having a significant environmental impact and presenting  significant  potential for improvement through design in terms of their environmental impact, without entailing excessive costs. Article 16(2)(a) of Directive 2009/125/EC provides that, in accordance with the procedure referred to in Article 19(3) and the criteria set out in Article 15(2), and after consulting the Ecodesign Consultation Forum, the Commission should, as appropriate, introduce imple- menting measures for products offering a high potential for cost-effective reduction of greenhouse gas emissions, such as for water heating equipment. The Commission has carried out a preparatory study on the technical, environmental and economic aspects of water heaters and hot water storage tanks typically used in the domestic and commercial sector. The study was devised together with stakeholders and interested parties from the Union and third countries, and the results have been made publicly available. The environmental aspects of water heaters that have been identified as significant for the purposes of this Regulation are energy consumption in the use phase () OJ L 285, 31.10.2009, p. 10. and (for heat pump water heaters) sound power levels. In addition, for water heaters using fossil fuels, emissions of nitrogen oxides, carbon monoxide and hydrocarbons are also identified as significant environmental aspects. The significant environmental aspect of hot water storage tanks is energy consumption due to their standing losses. It is not appropriate to set ecodesign requirements for emissions of carbon monoxide and hydrocarbons as no suitable European measurement methods are as yet available. With a view to developing such measurement methods, the Commission mandated the European stand- ardisation  organisations to  consider  ecodesign requirements for those emissions during the review of this Regulation. National provisions for ecodesign requirements on emissions of carbon monoxides and hydrocarbons of water heaters may be maintained until the corresponding Union ecodesign requirements enter into force. The provisions of Directive 2009/142/EC of the European Parliament and of the Council of 30 November 2009 relating to appliances burning gaseous fuels (3), which limit the combustion products of appliances burning gaseous fuels in relation to health and safety, are not affected. The preparatory study shows that requirements regarding the other ecodesign parameters referred to in Annex I, Part 1 to Directive 2009/125/EC are not necessary in the case of water heaters and hot water storage tanks. In particular, greenhouse gas emissions related to refriger- ants used in heat pump water heaters for heating today’s European building stock are not identified as significant. The appropriateness of setting ecodesign requirements for these greenhouse gas emissions will be reassessed when reviewing this Regulation. The scope of this Regulation should be limited to water heaters which are dedicated to providing hot drinking and sanitary water. Water heaters that are designed for using gaseous or liquid fuels predominantly (more than 50 %) produced from biomass have specific technical characteristics which require further technical, economic and environ- mental analyses. Depending on the outcome of the analyses, ecodesign requirements for those water heaters should be set at a later stage, if appropriate. () O] L 330, 16.12.2009, p. 10.
