Heating boilers - Part 6: Heating boilers with forced draught burners - Specific requirements for the domestic hot water operation and energy performance of water heaters and combination boilers with atomizing oil burners of nominal heat input not exceeding 70 kW
This document is composed of two parts.
The first part supplements EN 303-1, EN 303-2, EN 303-4 and EN 304, hereafter called boiler standards. It specifies the supplementary requirements and tests for the construction, safety, rational use of energy, fitness for purpose, classification and marking related to the domestic hot water operation of oil-fired water heaters and combination boilers.
The domestic hot water is produced on either the instantaneous or storage principle. The domestic hot water production is integrated or coupled, the whole being marketed as a single unit.
The second part covers the energy performance of domestic hot water production of the appliances covered by the first part.
This second part 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 such as kitchen, shower, bath and a combination of these, together with corresponding test procedures, enabling the energy performances of combination boilers and water heaters to be compared and matched to the needs of the user.
The heat output of the appliances covered by this standard does not exceed 400 kW.
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.
This standard only covers type testing.
Heizkessel - Teil 6: Heizkessel mit Gebläsebrennern - Spezielle Anforderungen an die trinkwasserseitige Funktion und energetische Bewertung von Wassererwärmern und von Kombi-Kesseln mit Ölzerstäubungsbrennern mit einer Nennwärmeleistung kleiner als oder gleich 70 kW
Dieses Dokument besteht aus zwei Teilen.
Der erste Teil vervollständigt die EN 303 1, EN 303 2, EN 303 4 und EN 304, nachfolgend Kesselnormen genannt. Er legt die zusätzlichen Anforderungen und Prüfungen für die Bauweise, die Sicherheit, die rationelle Energienutzung, die Gebrauchsgüte sowie die Einteilung und die Kennzeichnung bei der Betriebsart „Trinkwassererwärmung“ von ölbefeuerten Warmwasserbereitern und Kombi Kesseln fest.
Die Wassererwärmung erfolgt nach dem Durchlauf oder dem Speicherprinzip und ist integriert oder angebaut. Die Funktionen „Heizwassererwärmung“ und „Trinkwassererwärmung“ werden als Einheit vertrieben.
Der zweite Teil behandelt die Gesamtenergieeffizienz der Funktionen „Heizwassererwärmung“ und „Trinkwarmwassererwärmung“ der im ersten Teil behandelten Geräte.
Dieser zweite Teil legt ein Verfahren zur Bewertung der Gesamtenergieeffizienz der Geräte dar. Er definiert eine Anzahl an täglichen Zapfzyklen für jede Verwendungsart der Trinkwassererwärmung, wie beispiels¬weise Küche, Dusche, Bad, und eine Kombination dieser, zusammen mit den zugehörigen Prüfverfahren, wodurch die Gesamtenergieeffizienz der Kombi Kessel und Warmwasserbereiter verglichen und auf die Bedürfnisse des Anwenders abgestimmt werden kann.
Die Wärmeleistung der von dieser Norm behandelten Geräte darf 400 kW nicht überschreiten.
Im Falle von Kombi Kesseln mit oder ohne Speicher werden die Funktionen „Heizwassererwärmung“ und „Trinkwassererwärmung“ als Einheit vertrieben.
Die vorliegende Norm umfasst nur die Typprüfung.

Le présent document se compose de deux parties.
La première partie complète les normes EN 303 1, EN 303 2, EN 303 4 et EN 304, ci-après désignées normes chaudières. Elle définit les exigences et les essais complémentaires pour la construction, la sécurité, l'utilisation rationnelle de l'énergie, l'aptitude à la fonction, ainsi que la classification et le marquage concernant la fonction eau chaude sanitaire des chauffe-eau et des chaudières à deux services fonctionnant au fioul.
L'eau chaude sanitaire est produite selon la conception instantanée ou à accumulation. La production d'eau chaude sanitaire est intégrée ou accolée, l'ensemble étant commercialisé comme une seule unité.
La deuxième partie concerne les performances énergétiques de la production d'eau chaude sanitaire des appareils couverts par la première partie.
Elle établit également une méthode d'évaluation des performances énergétiques des appareils. Elle définit un nombre de cycles quotidiens de puisage pour chaque utilisation d'eau chaude sanitaire (par exemple, cuisine, douche et/ou bain), ainsi que les procédures d'essai correspondantes, afin de faciliter la comparaison des performances énergétiques des chaudières à deux services et des chauffe-eau, et d'adapter ces performances aux besoins de l'utilisateur.
La puissance utile des appareils couverts par la présente norme n'excède pas 400 kW.
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 présente norme couvre uniquement les essais de type.

Ta evropski standard je sestavljen iz dveh delov.
Prvi del dopolnjuje standarde EN 303 1, EN 303 2, EN 303 4 in EN 304, ki so v nadaljevanju imenovani standardi za kotle. Določa dopolnilne zahteve in preskuse za konstrukcijo, varnost, racionalno uporabo energije, primernost za namen, klasifikacijo ter označevanje v zvezi z delovanjem oljnih grelnikov sanitarne vode in kombiniranih kotlov.
Topla sanitarna voda se proizvaja po načelu pretočnosti ali po načelu shranjevanja. Proizvodnja tople sanitarne vode je integrirana ali združena, pri čemer se celota trži kot ena enota.
Drugi del zajema energijske lastnosti proizvodnje tople sanitarne vode z napravami, ki so zajete v prvem delu.
Ta drugi del določa metodo za ocenjevanje energetskih lastnosti naprav. Določa število dnevnih ciklov izpuščanja za vsako uporabo tople sanitarne vode, npr. za kuhinjo, prho, kad in njihove kombinacije, skupaj z ustreznimi preskusnimi postopki, da se omogoči primerjava energijskih lastnosti različnih kombiniranih kotlov in grelnikov vode ter njihova uskladitev s potrebami uporabnika.
Toplotna moč naprav, ki so zajete v tem standardu, ne presega 400 kW.
Pri kombiniranih kotlih, z rezervoarjem ali brez, je priprava tople sanitarne vode integrirana ali združena, pri čemer se celota trži kot ena enota.
Ta standard zajema le tipsko preskušanje.
