European foreword
This document (EN 13203-1:2015) has been prepared by Technical Committee CEN/TC 109 “Central
heating boilers using gaseous fuels”, the secretariat of which is held by NEN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by March 2016, and conflicting national standards shall
be withdrawn at the latest by March 2016.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent
rights.
This document supersedes EN 13203-1:2006.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
The main changes in this revision are the following:
— The title of this standard has been changed to: "Gas fired domestic appliances producing hot water
— Part 1: Assessment of performance of hot water deliveries";
— "heat input not exceeding 70 kW" was removed from the title but remains unchanged in the scope;
— "300 litres water storage" has been removed from the title and the scope is changed as following:
hot water storage capacity (if any) not exceeding 500 l;
— A new Clause 7 is added: "7 Eco design Related Products Data";
— An informative Annex ZA is added for the relationship between this European Standard and the
requirements of Commission Regulation (EU) n° 814/2013.
NOTE Useful standards are EN 26, EN 89, EN 15502-1, EN 15502-2-1 and EN 15502-2-2.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,

1 Scope
This European Standard is applicable to gas-fired appliances producing domestic hot water. It applies to
both instantaneous and storage appliances; water-heaters and combination boilers that have:
— heat input not exceeding 70 kW; and
— hot water storage capacity (if any) not exceeding 500 l.
In the case of combination boilers, with or without storage tank, domestic hot water production is
integrated or coupled, the whole being marketed as a single unit.
This European Standard sets out in qualitative and quantitative terms the performance in delivery of
domestic hot water for a selected variety of uses. It also gives a system for presenting the information to
the user.
