Slow heat release appliances fired by solid fuel - Requirements and test methods
This European Standard specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emission) instructions and marking together with associated test methods and test fuels for type testing residential slow heat release appliances fired by solid fuel.
This European Standard is applicable to hand fuelled intermittent burning slow heat release appliances having thermal storage capacity such that they can provide heat for a declared period of time after the fire has gone out. This European Standard also specifies a minimum time period from the appliance achieving the maximum differential surface temperature and falling to 50 % of that maximum value. These appliances provide heat into the space where they are installed.
These slow heat release appliances may be supplied either as an assembled appliance or as a manufacturer’s pre-designed unit consisting of pre-fabricated components designed to be built on site in accordance with the manufacturer’s specified assembly instructions. One off installations are not included.
These appliances may burn either solid mineral fuels, peat briquettes, natural or manufactured wood logs or be multi-fuel in accordance with the appliance manufacturer’s instructions. Wood pellets which are hand fuelled may also be burned either on the existing appliance bottomgrate or in a special basket arrangement which is placed by the user into the existing firebox.
This European Standard is not applicable to mechanically fed appliances, appliances having fan assisted combustion air or appliances with boiler.

The EN 15250:2007 standard provides a comprehensive framework for the requirements and test methods related to slow heat release appliances fired by solid fuel. Its scope is specifically tailored for residential hand-fuelled, intermittent burning appliances that are designed with thermal storage capacities, enabling them to emit heat effectively for a designated duration even after the fire has extinguished. This crucial feature not only enhances user comfort but also leads to improved energy efficiency, as the appliances can continue to radiate warmth long after the combustion process has ended. One of the primary strengths of this standard lies in its detailed provisions for safety and performance. By establishing rigorous requirements for design, construction, and operation, EN 15250:2007 ensures that appliances meet high safety standards while delivering optimal performance. The inclusion of efficiency and emission instructions further reflects its comprehensive approach to environmental considerations, addressing the need for cleaner emissions from solid fuel sources. Moreover, the document specifies the criteria for testing methods and fuels, which are essential for validating the performance claims of these appliances. This clarity in testing ensures consistency and reliability across different models and configurations, fostering consumer confidence in the performance of these heating solutions. The standard acknowledges various fuel types, including solid mineral fuels and wood logs, offering flexibility in fuel selection that aligns with user preferences and availability. The standard's applicability to both assembled appliances and pre-designed units underscores its relevance to manufacturers by accommodating various production strategies. This flexibility supports industry innovation and the adoption of diverse manufacturing practices while maintaining adherence to safety and performance benchmarks. However, it is crucial to note that EN 15250:2007 specifically excludes mechanically fed appliances, those with fan-assisted combustion air, and boiler-equipped units, thereby clearly delineating its focus on manual, traditional heating methods. This intentional limitation refines the standard’s applicability and reinforces its commitment to addressing the unique characteristics and needs of slow heat release appliances. In summary, the EN 15250:2007 standard plays a vital role in the realm of solid fuel appliances, providing essential guidelines that promote safety, efficiency, and proper performance validation. Its strengths in comprehensiveness and applicability to residential systems make it a relevant and valuable reference for manufacturers, designers, and consumers alike, ensuring the continued use and development of efficient heating solutions in homes.

EN 15250:2007は、固体燃料を使用した遅熱放出機器に関するヨーロッパ規格であり、デザイン、製造、構造、安全性、性能（効率および排出）に関する要件を詳細に定めています。この規格の主な強みは、住宅用の遅熱放出機器の設計とテスト方法の標準化にあります。 規格の範囲は、手動で燃料を供給する間欠的な遅熱放出機器に歩み寄り、これらの機器が火が消えた後に、指定された時間にわたって熱を供給できるようにするための熱貯蔵能力を備えていることを求めています。また、最大の表面温度差に達してからその最大値の50％に低下するまでの最小時間を明示し、使用者に安全で効率的な利用を促進します。 この規格の関連性は、高効率の暖房ソリューションを求める環境意識の高い消費者や業界にとって極めて重要です。固体鉱物燃料、ピートブリケット、天然または製造された木材ログ、さらには多燃料への対応が可能であり、これにより様々な燃料供給オプションを有し、柔軟性を持っています。特に、手動供給の木材ペレットを使用する機器においては、利用者が専用のバスケットを用いて簡単に燃料の供給ができる設計も考慮されています。 ただし、EN 15250:2007は、機械的に給餌される機器やファン付きの燃焼空気を持つ機器、ボイラー付の機器には適用されないため、対象となる市場を明確にし、特定の利用ニーズに対して適切な基準を提供しています。全体として、EN 15250:2007は、固体燃料を使用した遅熱放出機器の設計と運用の標準としての役割を果たし、業界全体における安全性と性能の向上に寄与する重要な文書です。
Die Norm EN 15250:2007 legt die Anforderungen an langsam Wärme abgebende Geräte fest, die mit festen Brennstoffen betrieben werden. Der Anwendungsbereich dieser europäischen Norm umfasst insbesondere handbeschickte, intermittierend brennende Geräte, die über eine thermische Speicherkapazität verfügen. Diese Geräte sind in der Lage, nach dem Erlöschen des Feuers Wärme über einen festgelegten Zeitraum bereitzustellen. Ein wesentliches Merkmal der Norm ist die Festlegung eines Mindestzeitraums, in dem die Temperatur des Geräts von der maximalen Oberflächentemperatur auf 50 % sinkt. Diese Vorschrift gewährleistet eine sichere Wärmeabgabe in dem Raum, in dem die Geräte installiert sind. Die Norm hebt die Sicherheits- und Leistungsanforderungen hervor, die für die Konstruktion und den Betrieb dieser HwZ-Geräte erforderlich sind. Sie definiert auch die entsprechenden Prüfmethoden und die hierfür benötigten Prüfmittel. Ein entscheidender Vorteil dieser Norm ist ihre Flexibilität, da die Heizgeräte entweder als fertig montierte Einheiten oder als vorkonfektionierte Komponenten angeboten werden können, die gemäß den Montageanweisungen des Herstellers vor Ort zusammengebaut werden. Die EN 15250:2007 gilt für eine Vielzahl von festen Brennstoffen, einschließlich mineralischer Brennstoffe, Torfbriketts, natürlichem oder künstlichem Holz. Zudem können auch handbeschickte Holzpellets unter bestimmten Bedingungen verwendet werden, was die Anwendbarkeit der Norm in der Praxis erweitert. Diese Norm ist jedoch nicht für mechanisch beschickte Geräte oder Geräte mit ventilatorunterstützter Verbrennungsluft vorgesehen, was die spezifische Zielgruppe der Norm klar abgrenzt. Insgesamt bietet die EN 15250:2007 wichtige Leitlinien für Hersteller und Installateure, um die Sicherheit und Effizienz von langsam Wärme abgebenden Geräten, die mit festen Brennstoffen betrieben werden, sicherzustellen. Die Norm ist damit von großer Relevanz für die Branche und trägt dazu bei, die Leistungsstandards für diese Art von Geräten in Europa zu harmonisieren.
