Gas-fired domestic appliances producing hot water - Appliances not exceeding 70 kW heat input and 300 l water storage capacity - 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 appliances; waters-heaters and combination boilers that have:
¾ heat input not exceeding 70 kW, and
¾ hot water storage capacity (if any) not exceeding 300 l.
In the case of combination boilers, with or without storage, domestic hot water production is integrated or coupled, the whole being marketed as a single unit.
This European Standard EN 13203 is formed in two parts, which cover two aspects of domestic hot water production.
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. This first part complements EN 26, EN 89 and EN 625.
The present European Standard EN 13203-2 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.
Gasbeheizte Geräte für die sanitäre Warmwasserbereitung für den Hausgebrauch - Geräte, die eine Nennwärmeleistung von 70 kW und eine Speicherkapazität von 300 Liter Wasser nicht überschreiten - Teil 2: Bewertung des Energieverbrauchs
Diese Europäische Norm gilt für gasbeheizte Geräte für die häusliche sanitäre Warmwasserbereitung. Sie gilt sowohl für Durchlauf-Wasserheizer als auch für Vorratswasserheizer und Kombi-Kessel mit Speicher, welche
- eine Wärmebelastung von 70 kW nicht überschreiten und
- ein Warmwasser-Speichervolumen von (sofern vorhanden) 300 l nicht überschreiten.
Bei Kombi-Kesseln mit oder ohne Vorratsbehälter ist die häusliche Warmwasserbereitung im Kessel eingebaut oder am Kessel angebaut. Das gesamte Gerät wird als eine Gesamteinheit vertrieben.
Diese Europäische Norm besteht aus zwei Teilen, die zwei Arten der häuslichen Warmwasserbereitung behandeln:
Der erste Teil EN 13203-1 legt mehrere quantitative und qualitative Niveaus für den Komfort von sanitärem Warmwasser für eine Auswahl von Benutzungsarten fest. Er enthält ebenfalls Hinweise zur entsprechenden Information des Betreibers. Dieser erste Teil vervollständigt EN 26, EN 89 und EN 625.
Der zweite Teil EN 13203-2 legt eine Methode zur Bewertung des Energieverhaltens von Geräten fest. Er definiert eine Anzahl täglicher Zapfprogramme für die häusliche Warmwasserverwendung in der Küche, zum Duschen und Baden und für Kombinationen dieser Verwendungsarten. Weiterhin legt er die entsprechenden Prüfverfahren fest, mit denen das Energieverhalten unterschiedlicher Geräte verglichen und auf die Bedürfnisse des Betreibers ausgerichtet werden kann.
Appareils domestiques produisant de l'eau chaude sanitaire utilisant les combustibles gazeux - Appareils de débit calorifique inférieur ou égal à 70 kW et de capacité de stockage inférieure ou égale à 300 litres - Partie 2 : Évaluation 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 ou à accumulation, chauffe-eau ou chaudières à deux services, qui ont :
- un débit calorifique inférieur ou égal à 70 kW ; et
- une capacité de stockage en eau (si elle existe) inférieure ou égale à 300 l.
Dans le cas des chaudières à deux services avec ou sans accumulation, la production d'eau chaude sanitaire est intégrée ou accolée, l'ensemble étant commercialisé comme une seule unité.
La norme EN 13203 est composée de deux parties qui couvrent deux aspects de la production de l'eau chaude sanitaire.
La norme EN 13203-1 définit en termes qualitatifs et quantitatifs la performance en puisage d'eau chaude sanitaire pour une variété d’usages sélectionnée. Cette partie complète l’EN 26, l’EN 89 et l'EN 625.
La présente norme EN 13203-2 définit une méthode pour déterminer les performances énergétiques des appareils. Elle définit cinq cycles de puisage journaliers pour l’usage d'eau chaude sanitaire, cuisine, douche, bain, et une combinaison de ces derniers, ainsi que les modalités d'essais correspondants, afin de pouvoir établir une comparaison des performances énergétiques des appareils utilisant les combustibles gazeux.
