EN 14829:2007 establishes comprehensive guidelines for independent gas-fired flueless space heaters with a nominal heat input not exceeding 6 kW. The standard's scope is pivotal as it delineates specific requirements and test methods essential for the construction, safety, marking, and rational energy use of 2nd and 3rd family gas-fired domestic flueless space heating appliances. One of the notable strengths of this standard lies in its focus on Type AAS fixed flueless heaters, equipped with atmosphere sensing devices, whether or not they include a fan. This emphasis ensures that safety measures are adequately met, particularly for heaters with catalytic converters and those classified under Category 1 and Category 2 appliances-thereby covering a broad range of common domestic setups. The clarity provided by the standard regarding what is not included is equally significant; it specifically excludes mobile heaters, portable flueless heaters, and diffusive catalytic combustion heaters. This specification helps prevent the misapplication of the standard and guides manufacturers and users alike in understanding its limitations. Moreover, the standard does not impose specific thermal efficiency requirements, rightly reflecting the nature of these appliances wherein all produced heat is utilized directly for space heating. This practical approach aligns with the essential safety requirements that ensure efficient combustion performance. Notably, the emphasis on type testing enhances the reliability of the appliances, as it establishes a direct correlation between performance and safety. In summary, EN 14829:2007 is a critical reference for manufacturers and users of gas-fired flueless space heaters, as it not only ensures safety and performance standards are met but also promotes efficient use of energy within the specified limitations of these heating appliances. Its relevance remains strong in today's market as demand for energy-efficient heating solutions continues to grow.
La norme EN 14829:2007, intitulée "Chauffages d'espace à gaz sans conduit à combustion indépendante pour une puissance thermique nominale n'excédant pas 6 kW", établit un cadre technique essentiel pour la sécurité et l'efficacité énergétique des chauffages d'espace domestiques. Cette norme spécifie les exigences et méthodes d'essai pour la construction, la sécurité, le marquage et l’utilisation rationnelle de l'énergie des appareils de chauffage à gaz sans conduit de 2ème et 3ème famille qui ont une entrée nominale ne dépassant pas 6 kW, en se basant sur la valeur calorifique nette. La norme couvre spécifiquement les chauffages fixes de type AAS, qui sont des appareils équipés d'un dispositif de détection de l'atmosphère, avec ou sans ventilateur. Elle inclut les chauffages avec ou sans convertisseur catalytique, ainsi que les appareils de catégorie 1 qui brûlent des gaz de la deuxième famille et ceux de catégorie 2 qui brûlent des gaz des deuxième et troisième familles. Cette exhaustivité témoigne de la pertinence de la norme dans le domaine des appareils de chauffage à gaz, en assurant une couverture adéquate pour différents types d’appareils spécifiques au marché domestique. Un des points forts de cette norme est sa focalisation sur la sécurité, en établissant des exigences claires concernant la performance de combustion. Bien qu'il n'y ait pas d'exigences spécifiques d'efficacité thermique pour ce type d'appareil, la norme garantit que toute la chaleur produite par le processus de combustion est libérée dans l'espace à chauffer, évitant ainsi des pertes énergétiques. Cela se traduit par une utilisation optimisée de l'énergie, ce qui est crucial pour les consommateurs soucieux d'économie d'énergie et d'impact environnemental. De plus, il est important de noter que la norme ne couvre pas certains appareils, tels que les chauffages mobiles et portables, ce qui lui confère une spécificité qui peut être bénéfique lors de l'examen type de produits destinés à des installations fixes. Cela permet aux fabricants de se concentrer sur une catégorie d’appareils qui répondent aux exigences de sécurité et de performance établies tout en minimisant les risques associés à d'autres types de chauffages. En résumé, la norme EN 14829:2007 joue un rôle primordial dans la réglementation des chauffages d'espace à gaz sans conduit, offrant des directives claires en matière de sécurité et d'utilisation de l'énergie, et représente un outil essentiel pour les fabricants et les consommateurs dans le secteur des appareils de chauffage domestiques.
Die Norm EN 14829:2007 behandelt unabhängige gasbetriebene raumluftunabhängige Heizgeräte mit einer nominalen Wärmeleistung von maximal 6 kW. Der Geltungsbereich dieser Norm ist klar definiert und richtet sich speziell an Typ AAS raumluftunabhängige Heizgeräte, die mit einem Atmosphärensensor ausgestattet sind, egal ob mit oder ohne Ventilator. Diese Geräte sind für den Einsatz in Wohnbereichen gedacht und müssen bestimmten Sicherheitsanforderungen, Prüfmethoden sowie Vorschriften zur Kennzeichnung und rationalen Energieverwendung entsprechen. Eine der Stärken dieser Norm liegt in ihrer spezifischen Fokussierung auf Sicherheitsaspekte der Geräte. Da alle Wärme, die durch den Verbrennungsprozess erzeugt wird, direkt in den zu beheizenden Raum abgegeben wird, wird die sichere Verbrennung des gaskraftbetriebenen Heizsystems gewährleistet. Dies ist insbesondere wichtig für die Gewährleistung eines sicheren Einsatzes im häuslichen Bereich. Die Schwellenwerte und Anforderungen für die zu prüfenden Heizgeräte sind klar umrissen, wobei die Norm erfordert, dass nur Geräte, die typgeprüft werden sollen, den Richtlinien entsprechen. Diese Präzision in den Vorgaben fördert die Standardisierung im Bereich gasbetriebener Heizgeräte und unterstützt Hersteller dabei, die nötigen Qualifikationen und Umstellungen zur Einhaltung der Norm zu gewährleisten. Obwohl die Norm keine spezifischen Anforderungen an die thermische Effizienz aufstellt, wird durch die Sicherheitsvorkehrungen hinsichtlich der Verbrennungsleistung sichergestellt, dass die Gasverbrennung effektiv und sicher erfolgt. Das ist ein wesentlicher Punkt, der die Relevanz dieser Norm unterstreicht, da die Sicherheit von Nutzern immer höchste Priorität haben sollte. Die EN 14829:2007 eignet sich nicht für mobile oder tragbare Heizgeräte sowie für bestimmte Kategorien, die nicht in den Geltungsbereich fallen. Dies zeigt die gezielte Ausrichtung der Norm auf fest installierte Geräte und schließt potenzielle Unsicherheiten bei der Verwendung aus. Insgesamt bietet die Norm EN 14829:2007 eine wertvolle Grundlage für Hersteller und Nutzer von gasbetriebenen Heizgeräten. Sie stellt sicher, dass alle spezifischen Anforderungen in Bezug auf Sicherheit und Konstruktion erfüllt sind und trägt damit zur Schaffung eines sicheren und effizienten Heizumfeldes bei.
EN 14829:2007は、6 kWを超えない定格熱出力を持つ独立式のガス-fired flueless space heaterに関する標準規格であり、その範囲は2ndおよび3rdファミリーのガスを用いた家庭用設備の建設、サポート、安全性、表記、およびエネルギーの合理的な利用に関する要件と試験方法を明確に定めています。この標準は、特に型AASの固定式flueless heaterに適用され、雰囲気を感知する装置を配置した型Aの器具に関して、カタリティックコンバーターの有無にかかわらず、きちんと規定しています。 この文書の強みは、その包括的なアプローチにあります。具体的には、定格出力に基づいた要求事項と試験方法が詳細に記されているため、ユーザーは安全で効果的な加熱解決策を容易に選択することができます。また、燃焼性能に関しても明確な要件が設定されており、これは安全面において非常に重要な要素です。すべての熱が加熱する空間に放出される構造であるため、これらの機器には特定の熱効率要件は不要とされていることも特徴的です。 EN 14829:2007は、移動式ヒーターやポータブル型のflueless heaterには適用されず、これにより利用者は目的に応じた正確な情報を得ることができます。さらに、品質保証システムや生産中の試験、補助装置の適合証明に関連する事項については扱われていないため、特定の用途にフォーカスした規格となっています。この点において、標準の関連性は非常に高く、特定の条件下での燃焼安全を確保するための効果的なガイドラインを提供しています。 全体として、EN 14829:2007はその包括的な範囲と安全性の確保に努めた要件により、家庭用のflueless space heaterの設計者および製造者にとって非常に重要な標準として位置づけられています。
