Residential solid fuel burning appliances - Part 2-4: Independent boilers - Nominal heat output up to 50 kW
This document is applicable to hand and automatically fired residential independent boilers (hereafter called appliances) having a nominal heat outputs up to 50 kW.
The primary function of the appliance is to provide hot water for central heating and/or domestic use. In addition to their primary function of providing hot water these appliances also provide space heating to the place of installation. They are designed for use only with open vented systems at a working pressure not exceeding 2 bar.
The appliances can burn one or more types of the following solid fuels in accordance with the appliance manufacturer’s instructions:
- wood logs;
- compressed untreated wood;
- wood pellets;
- lignite briquettes;
- solid mineral fuels;
- peat briquettes.
The appliances are operated closed and / or open.
The appliances are typed according to their tightness depending on their designation in accordance with a possible operation together with a room ventilation system.
This document is not applicable to appliances for hot water only production and having heat outputs of less than 5 kW.
This document is also not applicable for automatic stoking devices.
This document is used in conjunction with EN 16510 1 of which it is an integral part.

Dieses Dokument gilt für hand- und automatisch beschickte unabhängige Heizkessel für den Hausgebrauch (im Folgenden Geräte genannt) mit einer Nennwärmeleistungen bis 50 kW.
Die Hauptfunktion des Geräts ist die Bereitstellung von Warmwasser für die Zentralheizung und/oder den Hausgebrauch. Zusätzlich zu ihrer Hauptfunktion, der Bereitstellung von Warmwasser, dienen diese Geräte auch der Beheizung des Aufstellungsraumes. Sie sind nur für den Einsatz in offenen, entlüfteten Systemen mit einem Betriebsdruck von höchstens 2 bar vorgesehen.
Die Geräte können eine oder mehrere Arten der folgenden festen Brennstoffe nach den Anweisungen des Geräteherstellers verfeuern:
- Scheitholz;
- Holzbriketts;
- Holzpellets;
- Braunkohlenbriketts;
- feste mineralische Brennstoffe;
- Torfbriketts.
Die Geräte werden geschlossen und/oder offen betrieben.
Die Geräte werden nach ihrer Dichtheit entsprechend ihrer Bezeichnung in Abhängigkeit von einem möglichen Betrieb zusammen mit einem Raumlüftungssystem typisiert.
Dieses Dokument ist nicht anwendbar auf Geräte, die nur der Warmwasserbereitung dienen und eine Heizleistung von weniger als 5 kW haben.
Dieses Dokument ist auch nicht anwendbar für automatische Feuerungsanlagen.
Dieses Dokument wird in Verbindung mit EN 16510 1 angewendet, von der sie ein integraler Bestandteil ist.
Appareils de chauffage domestiques à combustible solide - Partie 2-4 : Chaudières à installer dans le volume habitable - Puissance utile nominale inférieure ou égale à 50 kW
Le présent document s’applique aux chaudières domestiques à combustion manuelle et automatique à installer dans le volume habitable (ci après dénommées « appareils ») ayant une puissance utile nominale inférieure ou égale à 50 kW.
La fonction principale de l’appareil est de fournir de l’eau chaude à des fins de chauffage central et/ou pour usage domestique. Outre leur fonction principale de fourniture d’eau chaude, ces appareils produisent également de la chaleur dans l’espace où ils sont installés. Ils ne sont conçus que pour être utilisés avec des systèmes à expansion ouverts à une pression de service ne dépassant pas 2 bar.
Ces appareils peuvent utiliser un ou plusieurs des types de combustibles solides suivants, conformément aux instructions du fabricant de l’appareil :
- bûches de bois ;
- bois compressé non traité ;
- granulés de bois ;
- briquettes de lignite ;
- combustibles minéraux solides ;
- briquettes de tourbe.
Ces appareils fonctionnent fermés et/ou ouverts.
Ils sont classés en fonction de leur étanchéité, de leur désignation et d’un fonctionnement éventuel avec un système de ventilation des locaux.
Le présent document ne s’applique pas aux appareils uniquement destinés à la production d’eau chaude ayant une puissance utile inférieure à 5 kW.
Il ne s’applique pas non plus aux dispositifs à chargement automatique.
Le présent document doit être utilisé conjointement avec l’EN 16510 1 qui en fait partie intégrante.
