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;
- a hot water storage tank capacity (if any) not exceeding 2 000 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.
The water heaters covered by the present standard are considered "conventional water heaters" as defined by the Transitional Methods (Commission Communication 2014/C 207/03) then in the calculation formula for the Annual Electricity Consumption (AEC), Qcor is equal to zero.
In case of the boiler is equipped with an internal or external Passive Flue Heat Recovery Device (PFHRD), the boiler efficiency can be assessed by applying EN 13203-2:2022 in combination with EN 13203-7:2022. In case of a PFHRD, where the technology has the ability to recover energy out of flue gasses during central heating production to be able to preheat the domestic hot water (indirect contribution), to assess this indirect contribution EN 13203-7:2022 applies. EN 13203-2:2022 is applicable for measuring and calculating the direct efficiency (direct contribution) while combining the measuring results of EN 13203-7:2022 the overall efficiency (direct and indirect) can be calculated. EN 13203-1:2015 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 specifies a few 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.
Gasgeräte für die häusliche Warmwasserbereitung - Teil 2: Bewertung des Energieverbrauchs
Dieses Dokument ist auf gasbefeuerte Geräte für die sanitäre Warmwasserbereitung anwendbar. Es gilt für sowohl Durchlauferhitzer als auch Warmwasserspeicher, Warmwasserbereiter sowie Kombikessel, die:
— eine Wärmebelastung von höchstens 400 kW und
— ein Warmwasser-Speichervolumen (sofern vorhanden) von höchstens 2 000 l haben.
Bei Kombikesseln mit oder ohne Speicher ist die sanitäre Warmwasserbereitung im Kessel eingebaut oder am Kessel angebaut, und das gesamte System wird als eine Einheit vertrieben.
Die von dieser Norm abgedeckten Warmwasserbereiter werden als „konventionelle Warmwasserbereiter“ angesehen, wie durch die „vorläufigen Methoden“ (Mitteilung der Kommission 2014/C 207/03) definiert; daher wird Qcor in der Formel zur Berechnung des jährlichen Stromverbrauchs (en: Annual Electricity Consumption, AEC), gleich null gesetzt.
Falls der Kessel mit einer internen oder externen passiven Abgas-Wärmerückgewinnungsanlage (en: passive flue heat recovery device, PFHRD) ausgerüstet ist, kann der Kesselwirkungsgrad mittels Anwendung von EN 13203 2:2022 in Verbindung mit EN 13203 7:2022 beurteilt werden. Im Falle einer PFHRD, die aufgrund der darin verbauten Technik in der Lage ist, während der Wärmeerzeugung für die Zentralheizung Energie aus den Abgasen zurückzugewinnen, um das sanitäre Warmwasser vorzuwärmen (indirekter Beitrag), gilt für die Beurteilung dieses indirekten Beitrags EN 13203 7:2022. EN 13203 2:2022 gilt für die Messung und Berechnung des direkten Wirkungsgrades (direkter Beitrag), während sich durch Kombination der nach EN 13203 7:2022 erhaltenen Messergebnisse der Gesamtwirkungsgrad (direkt und indirekt) berechnen lässt. EN 13203 1:2015 legt die Leistung bezüglich der Abgabe von sanitärem Warmwasser für eine Auswahl von Benutzungsarten qualitativ und quantitativ fest. Sie enthält zudem ein System zur Bereitstellung von Informationen für den Nutzer. Das vorliegende Dokument legt ein Verfahren zur Bewertung des Energieverhaltens der Geräte fest. Es legt einige tägliche Lastprofile für jede sanitäre Warmwasserverwendung in der Küche, zum Duschen und Baden sowie für Kombinationen dieser Verwendungsarten und die entsprechenden Prüfverfahren fest, mit denen sich das Energieverhalten unterschiedlicher gasbefeuerter Geräte vergleichen und auf die Bedürfnisse des Nutzers ausrichten lässt. Werden andere Technologien mit einem gasbefeuerten Kessel oder einem Warmwasserbereiter für die sanitäre Warmwasserbereitung kombiniert, so gelten die jeweils zutreffenden Teile von 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 des combustibles gazeux. Il s’applique à la fois aux appareils de type instantané et avec ballon, chauffe-eau ou chaudières mixtes, qui ont :
- un débit calorifique inférieur ou égal à 400 kW ; et
- une capacité du ballon d’eau chaude (le cas échéant) inférieure ou égale à 2 000 l.
Dans le cas des chaudières mixtes, avec ou sans ballon, la production d’eau chaude sanitaire est intégrée ou accolée, l’ensemble étant commercialisé comme une seule unité.
Les chauffe-eau couverts par la présente norme sont considérés comme des « chauffe-eau conventionnels » tels que définis par les méthodes transitoires de la Communication 2014/C 207/03 de la Commission ; pour ces chauffe-eau, dans la formule de calcul de la consommation annuelle d’électricité (AEC), le terme de correction Qcor est égal à zéro.
Les chaudières équipées d’un dispositif passif de récupération de la chaleur dans les produits de combustion (PFHRD), interne ou externe, peuvent être évaluées en appliquant l’EN 13203-2:2022 en combinaison avec l’EN 13203-7:2022. Dans le cas d’un PFHRD, où la technologie a la capacité de récupérer l’énergie des gaz de combustion lors de la production de chauffage central pour pouvoir préchauffer l’eau chaude sanitaire (contribution indirecte), pour évaluer cette contribution indirecte l’EN 13203-7:2022 s’applique. L’EN 13203-2:2022 est applicable pour mesurer et calculer l’efficacité directe (contribution directe) tandis que la combinaison des résultats de mesurage de l’EN 13203-7:2022 permet de calculer l’efficacité globale (directe et indirecte). L’EN 13203-1:2015 définit, en termes qualitatifs et quantitatifs, la performance en 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 spécifie quelques profils de soutirage journaliers pour chaque utilisation d’eau chaude sanitaire, pour la cuisine, la douche, le bain et une combinaison de ces utilisations, ainsi que les modes opératoires d’essai correspondants, ce qui permet de comparer les performances énergétiques des différents appareils utilisant les combustibles gazeux et de les adapter aux besoins de l’utilisateur. Des parties spécifiques de l’EN 13203 s’appliquent lorsque d’autres technologies sont associées à une chaudière ou un chauffe-eau utilisant les combustibles gazeux pour produire de l’eau chaude sanitaire.
