EN 13203-2:2018

Gas-fired domestic appliances producing hot water - Part 2: Assessment of energy consumption

This document is applicable to gas-fired appliances producing domestic hot water. It applies to both instantaneous and storage tank appliances; waters-heaters and combination boilers that have:
- a heat input not exceeding 400 kW; and
- a hot water storage tank capacity (if any) not exceeding 2000 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.
EN 13203-1 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. The present document sets out a method for assessing the energy performance of the appliances. It defines a number of daily load profiles for each domestic hot water use, kitchen, shower, bath and a combination of these, together with corresponding test procedures, enabling the energy performances of different gas-fired appliances to be compared and matched to the needs of the user. Where other technologies are combined with a gas-fired boiler or a water heater to produce domestic hot water, specific parts of EN 13203 apply.

Gasbeheizte Geräte für die Warmwasserbereitung für den Hausgebrauch - Teil 2: Bewertung des Energieverbrauchs

Dieses Dokument gilt für gasbeheizte Geräte für die sanitäre Warmwasserbereitung. Sie gilt sowohl für Durchlauferhitzer als auch Warmwasserspeicher, Warmwasserbereiter sowie Kombikessel mit:
-   einer Wärmebelastung von höchstens 400 kW; und
-   einem Warmwasser-Speichervolumen (sofern vorhanden) von höchstens 2 000 l.
Bei Kombikesseln mit oder ohne Speicher ist die sanitäre Warmwasserbereitung im Kessel eingebaut oder am Kessel angebaut; das Gerät wird als eine Gesamteinheit vertrieben.
EN 13203 1 legt mehrere qualitative und quantitative Leistungsstufen für die sanitäre Warmwasserbereitung für eine Auswahl von Benutzungsarten fest. Sie enthält zudem ein System zur Bereitstellung von Informationen für den Nutzer. Dieses Dokument legt ein Verfahren zur Bewertung des Energieverhaltens der Geräte fest. Es definiert eine Anzahl täglicher Lastprofile für die sanitäre Warmwasserverwendung in der Küche, zum Duschen und Baden sowie für Kombinationen dieser Verwendungsarten und legt die entsprechenden Prüfverfahren fest, mit denen sich das Energieverhalten unterschiedlicher gasbeheizter Geräte vergleichen und auf die Bedürfnisse des Nutzers ausrichten lässt. Werden andere Technologien mit einem gasbeheizten Kessel oder einem Warmwasserbereiter für die sanitäre Warmwasserbereitung kombiniert, gelten die jeweils zutreffenden Teile der EN 13203.

Appareils domestiques produisant de l’eau chaude sanitaire utilisant les combustibles gazeux - Partie 2 : Évaluation de la consommation énergétique

Le présent document s’applique aux appareils de production d’eau chaude sanitaire utilisant les combustibles gazeux. Elle s’applique à la fois aux appareils de type instantané et avec ballon, chauffeeau ou chaudières à deux services, qui ont :
- un débit calorifique inférieur ou égal à 400 kW ; et
- une capacité de stockage en eau chaude (le cas échéant) inférieure ou égale à 2 000 l.
Dans le cas des chaudières à deux services avec ou sans ballon, la production d’eau chaude sanitaire est intégrée ou accolée, l’ensemble étant commercialisé comme une seule unité.
L’EN 13203-1 définit en termes qualitatifs et quantitatifs la performance du puisage d’eau chaude sanitaire pour une variété sélectionnée d’usages. Elle fournit également un système pour présenter les informations à l’utilisateur. Le présent document définit une méthode pour évaluer les performances énergétiques des appareils. Il définit plusieurs profils de soutirage journaliers pour chaque utilisation d’eau chaude sanitaire, cuisine, douche, bain et une combinaison de ces derniers, ainsi que les modes
opératoires d’essai correspondants, afin de pouvoir établir une comparaison des performances
énergétiques des appareils utilisant les combustibles gazeux et de les adapter aux besoins de
l’utilisateur. Si d’autres technologies sont combinées avec une chaudière à gaz ou un chauffe-eau pour
produire de l’eau chaude sanitaire, des parties spécifiques de l’EN 13203 s’appliquent.

Plinske gospodinjske naprave za pripravo tople sanitarne vode - 2. del: Ocenjevanje rabe energije

Ta evropski standard se uporablja za plinske gospodinjske naprave za pripravo tople sanitarne vode. uporablja se za pretočne in shranjevalne rezervoarje, grelnike za vodo in kombinirane kotle s:
– toplotno močjo, ki ne presega 70 kW in
– prostornino rezervoarja (če je na voljo) za toplo vodo do 500 l.
Pri kombiniranih kotlih, z rezervoarjem ali brez, je priprava tople vode za gospodinjstva integrirana ali združena, pri čemer se celota trži kot ena enota.
Standard EN 13203-1 v kakovostnem in količinskem smislu določa zmogljivost za pripravo tople sanitarne vode za različne izbrane namene. Zajema tudi sistem za predstavitev informacij uporabniku. Ta dokument določa metodo za ocenjevanje energetske učinkovitosti aparatov. Določa število dnevnih ciklov izpuščanja za vsako uporabo gospodinjske tople vode, kuhinjo, prho, kad in njihove kombinacije, skupaj z ustreznimi preskusnimi postopki, za omogočanje energijske zmogljivosti različnih plinskih naprav za primerjavo in uskladitev s potrebami uporabnika. Posebni deli standarda EN 13203 se uporabljajo, kadar so druge tehnologije združene s plinskimi kotli ali vodnimi grelniki za pripravo tople sanitarne vode.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 13203-2:2015.
The main technical changes compared to EN 13203-2:2015 are the following:
— improvement of the test conditions (e.g. water supply, initial adjustment of the appliance);
— addition of further load profile XS for small appliances;
