EN 13203-2:2015

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

This European Standard 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 70 kW; and
-   a hot water storage tank 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.
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 tapping cycles 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 sanitäre Warmwasserbereitung für den Hausgebrauch - Teil 2: Bewertung des Energieverbrauchs

Diese Europäische Norm gilt für gasbefeuerte Geräte für die sanitäre Warmwasserbereitung. Sie gilt sowohl für Durchlauf- als auch für Speicher-Warmwasserbereiter sowie Kombi-Kessel mit:
-   einer Wärmebelastung von höchstens 70 kW; und
-   einem Warmwasser-Speichervolumen (sofern vorhanden) von höchstens 500 l.
Bei Kombi-Kesseln mit oder ohne Speicher ist die sanitäre Warmwasserbereitung im Kessel eingebaut oder am Kessel angebaut; das gesamte Gerät wird als eine Gesamteinheit vertrieben.
EN 13203 1 legt mehrere quantitative und qualitative Leistungsstufen für die sanitäre Warmwasser¬bereitung für eine Auswahl von Benutzungsarten fest. Sie enthält ebenfalls ein System zur Bereitstellung von Angaben für den Betreiber. Dieses Dokument legt ein Verfahren zur Bewertung des Energieverhaltens der Geräte fest. Es definiert eine Anzahl täglicher Zapfprogramme für die sanitäre Warmwasserverwendung in der Küche, zum Duschen und Baden sowie für Kombinationen dieser Verwendungsarten und legt die entsprechenden Prüfverfahren fest, mit denen das Energieverhalten unterschiedlicher gasbefeuerter Geräte verglichen und auf die Bedürfnisse des Benutzers ausgerichtet werden kann. Werden andere Technologien mit einem gasbefeuerten Kessel oder einem Warmwasserbereiter für sanitäres Warmwasser kombiniert, gelten die jeweils zutreffenden Teile der EN 13203.

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

La présente Norme européenne s’applique aux appareils de production d’eau chaude sanitaire utilisant les combustibles gazeux. Elle s’applique à la fois aux appareils instantanés et avec ballon, chauffe-eau ou chaudières à deux services, qui ont :
-   un débit calorifique inférieur ou égal à 70 kW ; et
-   une capacité du ballon (le cas échéant) inférieure ou égale à 500 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.
La norme 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 déterminer les performances énergétiques des appareils. Elle définit plusieurs cycles de soutirage journaliers pour chaque utilisation d’eau chaude sanitaire, cuisine, douche, bain, et une combinaison de ces derniers, ainsi que les modalités d’essais correspondantes, afin de pouvoir établir une comparaison des performances énergétiques des appareils utilisant les combustibles gazeux. Si d’autres technologies sont combinées avec une chaudière à gaz ou un appareil de chauffage de l’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 porabe energije

Ta evropski standard se uporablja za plinske gospodinjske naprave za pripravo tople sanitarne vode. Velja 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 vročo 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 veljajo, kjer so druge tehnologije združene s plinskimi kotli ali vodnimi grelniki za pripravo tople sanitarne vode.

Introduction
The safety operation of the boiler or water heater is not covered by this standard. Safety should be proved by
means of the essential safety requirements of the Gas Appliances Directive 2009/142/EC. This may be
achieved by compliance with the appropriate existing harmonized standards.
NOTE Useful standards are EN 26, EN 89, EN 15502-1, EN 15502-2-1 and EN 15502-2-2.
1 Scope
This European Standard 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 70 kW; and
— a hot water storage tank 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.
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 tapping cycles 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.
