Solar supported gas-fired domestic appliances producing hot water - Appliances not exceeding 70 kW heat input and 500 litres water storage capacity - Part 3: Assessment of energy consumption
This document is applicable to solar supported gas-fired appliances producing domestic hot water.
It applies to a system marketed as single unit or a fully specified system that:
- has a gas heat input not exceeding 70 kW; and
- has a hot water storage tank capacity not exceeding 500 l; and
- is equipped with at least one solar collector; and
- is, with regard to the solar hydraulic circuit, considered as a forced circulation system (definition according to EN ISO 9488:1999).
The appliances covered by this European Standard are described in Annex E (normative).
This document does not apply to thermo-siphon or integral collector storage tank systems according to definitions given by EN ISO 9488:1999.
NOTE In principle, the energy consumption of thermo-siphon solar preheat systems and integral collector storage tank preheat systems can also be assessed on the basis of this standard. One appropriate procedure for that purpose is to calculate the temperature level of the domestic hot water withdrawn from the thermal solar system for the reference conditions defined in this standard by using the numerical system model and the thermal solar system performance parameters according to ISO 9459-5. Based on the temperature level of the hot water withdrawn from the store the energy consumption of the gas appliance should be determined. This determination can either be done by means of calculations or by performing a test according to FprEN 13203-2:2020 and using instead of the cold water inlet temperature the hot water temperature withdrawn from the store.
This document is not intended to assess the performance:
- of the solar collector(s), which should comply with EN 12975-1:+A1:2010 and EN 12975-2:2006; and - thermal solar systems and components, which should comply with EN 12976-1:2017 and EN 12976- 2:2019.
Standard 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 presenting the information to the user. The present document sets out a method for assessing the energy performance of a solar supported appliance. 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 including information about the available solar radiation. It enables the energy performances of different gas-fired appliances to be compared and matched to the needs of the user.
Solar unterstützte Gasgeräte für die häusliche Warmwasserbereitung - Geräte, die eine Nennwärmebelastung von 70 kW und eine Speicherkapazität von 500 Liter Wasser nicht überschreiten - Teil 3: Bewertung des Energieverbrauchs
Dieses Dokument ist auf solar unterstützte gasbeheizte Geräte für die sanitäre Warmwasserbereitung anwendbar. Es gilt für Systeme, die als einzelne Einheit vertrieben werden oder vollständig festgelegt sind und die:
— eine Wärmebelastung von höchstens 70 kW; und
— ein Warmwasser-Speichervolumen von höchstens 500 l haben; und
— mit mindestens einem Sonnenkollektor ausgerüstet sind; und
— im Hinblick auf den solaren hydraulischen Kreislauf als ein erzwungenes Umlaufsystem betrachtet werden (Begriffsbestimmung nach EN ISO 9488:1999).
Die Geräte, für die diese Europäische Norm gilt, werden in Anhang E (normativ) beschrieben.
Dieses Dokument ist nicht anwendbar für Thermo-Syphon-Speichersysteme oder integrierte Kollektor-Speichersysteme nach den in EN ISO 9488:1999 angegebenen Begriffsbestimmungen.
Im Prinzip kann jedoch der Energieverbrauch von solar vorgeheizten Thermo-Syphon-Speichersystemen und solar vorgeheizten integrierten Kollektor-Speichersystemen auf der Grundlage dieses Dokuments bewertet werden. Eine geeignete Verfahrensweise für diesen Zweck ist, das Temperaturniveau des aus dem thermischen Solarsystem gezapften häuslichen Warmwassers für die in dieser Norm festgelegten Referenzbedingungen mit Hilfe des numerischen Modellsystems und der Leistungsparameter des thermischen Solarsystems nach ISO 9459-5 zu berechnen. Anhand des Temperaturniveaus des aus dem Speicher gezapften Warmwassers wird der Energieverbrauch des Gasgerätes bestimmt. Diese Bestimmung kann entweder anhand von Berechnungen oder mittels Durchführung einer Prüfung nach prEN 13203-2:2020 und unter Verwendung der Temperatur des aus dem Speicher gezapften Warmwassers anstelle der Kaltwasser-Eintrittstemperatur erfolgen.
Dieses Dokument ist nicht dafür vorgesehen, die Gebrauchstauglichkeit
— des Solarkollektors bzw. der Sonnenkollektoren, der (die) EN 12975-1+A1:2010 und EN 12975-2:2006 entsprechen sollte(n); und
— von thermischen Solarsystemen und Bauteilen, die EN 12976-1:2017 und EN 12976-2:2019 entsprechen sollten, zu beurteilen.
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.
Dieses Dokument legt ein Verfahren zur Beurteilung des Energieverhaltens eines solar unterstützten Gerätes fest. Es legt eine Anzahl von täglichen Zapfvorgängen für jede häusliche Warmwasserverwendung in Küche, Dusche, Bad und einer Kombination dieser Anwendungen zusammen mit entsprechenden Prüfverfahren einschließlich Information über die verfügbare Solarstrahlung fest. Es ermöglicht, das Energieverhalten verschiedener gasbeheizter Geräte zu vergleichen und trifft damit die Bedürfnisse des Anwenders.

Le présent document s’applique aux appareils de production d’eau chaude sanitaire utilisant des combustibles gazeux et couplés à un capteur solaire. Il s’applique aux systèmes commercialisés comme une seule unité ou comme un système entièrement spécifié :
— qui ont un débit calorifique de gaz inférieur ou égal à 70 kW ; et
— qui ont une capacité du ballon d’eau chaude inférieure ou égale à 500 l ; et
— qui sont équipés d’au moins un capteur solaire ; et
— qui sont, au regard du circuit hydraulique solaire, considérés comme des systèmes à circulation forcée (définition selon l’EN ISO 9488:1999).
Les appareils couverts par la présente Norme européenne sont décrits à l’Annexe E (normative).
Le présent document ne s’applique pas aux installations à thermosiphon ou à capteur auto-stockeur conformément aux définitions données par l’EN ISO 9488:1999.
En principe, il peut servir à évaluer la consommation énergétique des installations de préchauffage solaire, qu’elles soient à thermosiphon ou à capteur autostockeur. Pour ce faire, il faut calculer le niveau de température de l’eau chaude domestique puisée de l’installation solaire thermique dans les conditions de référence définies dans la présente norme à partir du modèle numérique de l’installation et des paramètres de performance de l’installation solaire thermique conformément à l’ISO 9459-5. Selon le niveau de température de l’eau chaude puisée du ballon, la consommation d’énergie de l’appareil à gaz est déterminée. Cette détermination peut se faire, soit par calcul, soit par un essai conformément au prEN 13203-2:2020 en remplaçant la température d’eau froide par la température de l’eau chaude puisée du ballon.
Le présent document n’est pas destiné à évaluer la performance :
— des capteurs solaires, dont il convient que les caractéristiques soient conformes à l’EN 12975-1+A1:2010 et à l’EN 12975-2:2006 ; et
— des installations solaires thermiques et leurs composants, dont il convient que les caractéristiques soient conformes à l’EN 12976-1:2017 et à l’EN 12976-2:2019.
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 mentionne également un système pour présenter les informations à l’utilisateur.
Le présent document définit une méthode pour évaluer les performances énergétiques d’un système couplé à un appareil solaire. Il définit différents 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 associés à des informations sur le rayonnement solaire disponible. Le présent document permet ainsi d’établir une comparaison des performances énergétiques des appareils utilisant des combustibles gazeux et de les adapter aux besoins de l’utilisateur.

1 Scope
This document is applicable to solar supported gas-fired appliances producing domestic hot water. It
applies to a system marketed as single unit or a fully specified system that:— has a gas heat input not exceeding 70 kW; and
— has a hot water storage tank capacity not exceeding 500 l; and
— is equipped with at least one solar collector; and
— is, with regard to the solar hydraulic circuit, considered as a forced circulation system (definition
according to EN ISO 9488:1999).The appliances covered by this European Standard are described in Annex E (normative).
This document does not apply to thermo-siphon or integral collector storage tank systems according to
definitions given by EN ISO 9488:1999.In principle, the energy consumption of thermo-siphon solar preheat systems and integral collector
storage tank preheat systems can also be assessed on the basis of this document. One appropriate
procedure for that purpose is to calculate the temperature level of the domestic hot water withdrawn
from the thermal solar system for the reference conditions defined in this standard by using the
numerical system model and the thermal solar system performance parameters according to
ISO 9459-5. Based on the temperature level of the hot water withdrawn from the store the energy
consumption of the gas appliance is determined. This determination can either be done by means of
calculations or by performing a test according to prEN 13203-2:2020 and using instead of the cold
water inlet temperature the hot water temperature withdrawn from the store.This document is not intended to assess the performance:
— of the solar collector(s), which should comply with EN 12975-1+A1:2010 and EN 12975-2:2006;
and— thermal solar systems and components, which should comply with EN 12976-1:2017 and
EN 12976-2:2019.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 presenting the information to the user.
The present document sets out a method for assessing the energy performance of a solar supported
appliance. 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 including information
about the available solar radiation. It enables the energy performances of different gas-fired appliances
to be compared and matched to the needs of the user.2 Normative references
