            COMMISSION IMPLEMENTING DECISION (EU) 2026/1717
of 20 July 2026
         
on the harmonised standards for gas water heaters drafted in support of Regulation (EU) No 814/2013 and of Delegated Regulation (EU) No 812/2013


THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,


Having regard to Regulation (EU) No 1025/2012 of the European Parliament and of the Council of 25 October 2012 on European standardisation, amending Council Directives 89/686/EEC and 93/15/EEC and Directives 94/9/EC, 94/25/EC, 95/16/EC, 97/23/EC, 98/34/EC, 2004/22/EC, 2007/23/EC, 2009/23/EC and 2009/105/EC of the European Parliament and of the Council and repealing Council Decision 87/95/EEC and Decision No 1673/2006/EC of the European Parliament and of the Council (1), and in particular Article 10(6) thereof,

Whereas:







(1)


In accordance with Article 9(2) of Directive 2009/125/EC of the European Parliament and of the Council (2), gas water heaters that conform to harmonised standards or parts thereof, the references of which have been published in the Official Journal of the European Union, are to be regarded as conforming to all the relevant requirements of the applicable implementing measure to which such standards relate.












(2)


In Implementing Decision C(2015) 2625 (3), the Commission requested that the European Committee for Standardisation (CEN) draft harmonised standards in support of the implementation of Commission Regulation (EU) No 814/2013 (4) laying down ecodesign requirements for water heaters and hot water storage tanks and of Commission Delegated Regulation (EU) No 812/2013 (5) with regard to the energy labelling of water heaters, hot water storage tanks and packages of water heater and solar device.












(3)


On the basis of the request set out in Implementing Decision C(2015) 2625, CEN has published adapted standards (6), in particular the standard EN 13203-1:2025 regarding water heaters.












(4)


The Commission together with the CEN has assessed whether this standard EN 13203-1:2025 drafted by the CEN complies with the request M/534 of 28 April 2015.












(5)


The findings of this assessment are that the standard satisfies the requirements it aims to cover, set out in Regulation (EU) No 814/2013 and Delegated Regulation (EU) No 812/2013. It is therefore appropriate to publish the reference of this standard in the Official Journal of the European Union.












(6)


Compliance with a harmonised standard confers a presumption of conformity to the corresponding essential requirements, including the safety objectives, set out in Union harmonisation legislation from the date of publication of the reference of the standard in question in the Official Journal of the European Union. This Decision should therefore enter into force on the day of its publication,





HAS ADOPTED THIS DECISION:



Article 1
The references of harmonised standards for water heaters drafted in support of Regulation (EU) No 814/2013 and Delegated Regulation (EU) No 812/2013 listed in the Annexes to this Decision, shall be published in the Official Journal of the European Union.


Article 2
This Decision shall enter into force on the day of its publication in the Official Journal of the European Union.
