3.6.2014 Official Journal of the European Union L 164/83 COMMISSION DECISION of 28 May 2014 establishing the criteria for the award of the EU Ecolabel for water-based heaters (notified under document C(2014) 3452) (Text with EEA relevance) (2014/314[EU) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EC) No 66/2010 of the European Parliament and of the Council of 25 November 2009 on the EU Ecolabel ('), and in particular Article 8(2) thereof, After consulting the European Union Ecolabelling Board, Whereas: (1)  Under Regulation (EC) No 66/2010, the EU Ecolabel may be awarded to products which have a reduced environ- mental impact during their entire life cycle. (2)  Regulation (EC) No 66/2010 provides that specific EU Ecolabel criteria are to be established according to product groups. (3)  The Commission has drawn up a preliminary report on the technical, environmental, economic and legal aspects of the product group ‘water-based heaters’ typically used in the Union and made it publicly available for comment. The study on which this report is based (hereinafter ‘the study’) was devised together with stakeholders and interested parties from the Union and third countries. (4)  The results of the study, presented in the preliminary report, have shown that energy consumption in the use phase contributes most significantly to the overall environmental impact of water-based heaters. Therefore, the use of energy-efficient and low greenhouse gas-emitting water-based heaters should be promoted and, in addition, such heaters using more environmental friendly technologies and proven to be safe for consumers should be supported. (5) It is appropriate to establish EU Ecolabel criteria for the product group ‘water-based heaters’. (6) The criteria, as well as the related assessment and verification requirements, should be valid for four years from the date of adoption of this Decision. (7)  The measures provided for in this Decision are in accordance with the opinion of the Committee established by Article 16 of Regulation (EC) No 66/2010, HAS ADOPTED THIS DECISION: Article 1 1. The product group ‘water-based heaters’ shall comprise products that are used to generate heat as part of a water- based central heating system, where the heated water is distributed by means of circulators and heat emitters in order to reach and maintain the indoor temperature of an enclosed space such as a building, a dwelling, or a room, at a desired level. The heat generator generates heat by means of one or more of the following processes and technologies: (a) combustion of gaseous, liquid or solid fossil fuels; (b) combustion of gaseous, liquid or solid biomass; (c) use of the Joule effect in electric resistance heating elements; () 0JL27,30.1.2010,p. 1.
