Residential space heating appliances fired by wood pellets - Requirements and test methods

This European Standard specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emissions), instructions and marking together with associated test methods and test fuels for type-testing residential space heaters fired by wood pellets, and mechanically fed up to 50 kW nominal heat output.
These appliances may be freestanding or inset appliances and provide heat into the space where they are installed and may be operated with either natural draught or fan-assisted combustion air. Additionally, where fitted with a boiler, they also provide domestic hot water and/or central heating. These appliances burn wood pellets only, in accordance with the appliance manufacturer's instructions. They operate with firedoors closed only.
Non mechanically fed appliances burning solid mineral fuels, peat briquettes and natural or manufactured wood logs are not included in this European Standard, but are covered by EN 13229 and EN 13240.
NOTE   These appliances may have an integral fuel hopper or be combined with an external fuel hopper.

Raumheizer zur Verfeuerung von Holzpellets - Anforderungen und Prüfverfahren

Diese Europäische Norm legt Anforderungen an Auslegung, Herstellung, Ausführung, Sicherheit und Leistungsvermögen (Wirkungsgrad und Emission), Anleitung und Kennzeichnung zusammen mit zugehörigen Prüfverfahren und Prüfbrennstoffen für die Typprüfung von Raumheizern für Holzpellets mit einer Nennwärmeleistung bis 50 kW fest, die mechanisch beschickt werden.
Diese Feuerstätten dienen der Raumheizung, gegebenenfalls auch der Brauchwassererzeugung. Sie können mit natürlichem Förderdruck oder mit gebläseunterstützter Verbrennungsluftzufuhr betrieben werden. Sofern sie mit wasserführenden Bauteilen ausgestattet sind, beheizen sie auch Heizwasser und/oder Brauchwasser. Diese Feuerstätten können entsprechend der Bedienungsanleitung des Herstellers Holzpellets nur mit geschlossenen Feuerraumtüren verfeuern.
Nicht mechanisch beschickte Feuerstätten für feste mineralische Brennstoffe, Torfbriketts, Holzscheite und Holzbriketts sind nicht Gegenstand dieser Europäischen Norm, diese werden behandelt in der EN 13229 und EN 13240.
ANMERKUNG   Sie können mit einem integrierten oder externen Füllraum für Brennstoff ausgestattet sein.

Appareils de chauffage domestique à convection à granulés de bois - Exigences et méthodes d'essai

La présente Norme européenne définit les exigences relatives à la conception, à la fabrication, à l’assemblage,
à la sécurité, aux performances (rendement et émissions), aux instructions et au marquage ainsi que les
méthodes et combustibles correspondants pour les essais des appareils de chauffage domestiques à
granulés de bois et à alimentation mécanique d'une puissance calorifique nominale allant jusqu'à 50 W.
Ces appareils peuvent être indépendants ou encastrés et fournissent de la chaleur dans l'espace où ils sont
installés ; ils peuvent fonctionner en tirage naturel ou être équipés d'un ventilateur pour l'alimentation en air de
combustion. De plus, lorsqu’ils sont équipés d'une chaudière, ils fournissent également de l’eau chaude
sanitaire et/ou du chauffage central. Ces appareils utilisent le granulé de bois uniquement, conformément aux
instructions du fabricant de l'appareil. Ils fonctionnent uniquement avec des portes de foyer fermées.
La présente Norme européenne ne traite pas des appareils dépourvus d’alimentation mécanique qui utilisent
des combustibles minéraux solides, des briquettes de tourbe et des bûches de bois naturelles ou
reconstituées ; ces appareils font l'objet des normes EN 13229 et EN 13240.
NOTE Ces appareils peuvent comporter une trémie d’alimentation intégrée ou être combinés avec une trémie
d’alimentation externe.
