Residential solid fuel burning appliances - Part 2-5: Slow heat release appliances

This European
Standard is applicable to residential freestanding hand fuelled intermittent burning slow
heat release appliances having thermal storage capacity such that they can provide
heat for an extended period of time after the fire has gone out. Maximum firing time is 3
hours. These slow heat release appliances may be supplied either as an assembled
appliance or as a manufacturer’s predesigned
unit consisting of
prefabricated components designed to be built on site in accordance with the
manufacturer’s specified assembly instructions. One off installations are not included
as they are not covered by the scope of this standard. This European standard is also
applicable to appliances which are designed for operating under room
sealed conditions and which are intended to be installed into a chimney not serving any
other appliances. These appliances can contain also fluid heating device which can be
either a boiler or a heat exchanger that is not in contact with flames or flue gases. Note:
Appliances which receive their combustion air from outside by means of a pipe system
which is not air tight are not considered room sealed in accordance with this
standard. This European Standard specifies requirements relating to the design,
manufacture, construction, safety and performance (efficiency and emission) together
with associated test methods and test fuels for residential slow heat release appliances
fired by solid fuel (hereafter referred to as “appliances”), and provides instructions for
them. Furthermore, it also gives provisions for evaluation of conformity i.e. initial type
testing (ITT) and factory production control (FPC) and marking of these
appliances. These appliances provide heat by radiation and convection from the
surface and can also have channels for improved convection. They provide heat into
the space where they are installed. Additionally if fitted with a boiler or a heat
exchanger that is not in contact with flames or flue gases, these appliances may also
provide domestic hot water and/or central heating. These appliances may burn either
solid mineral fuels, peat briquettes, natural or manufactured wood logs or be multifuel
fired in accordance with the appliance manufacturer’s instructions. Wood pellets which are specifically intended to be hand fuelled can be burned either on the existing
appliance bottom grate 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. This European standard is also not applicable to appliances which are
designed to be operated with ventilating systems which have pressure below (– 15 Pa)
in relation to the outside atmosphere as measured in the room where the appliance
is installed. This European Standard covers also CO, NOx, OGC (total hydrocarbons)
and particulate matter emission test methods; however it does not contain any values
for the limit on these emissions. This part 25
of a European Standard series is
applicable to slow heat release appliances. This part 25
is to be used in conjunction
with the latest edition of EN 165101
and its amendments. It is established on the basis
of EN 165101:
2015. When this standard states “addition”, “modification”
or “replacement”, the relevant text in part 1 is to be adapted accordingly.

Häusliche Feuerstätten für feste Brennstoffe - Teil 2-5: Speicherfeuerstätten

Dieses Dokument ist anzuwenden für Speicherfeuerstätten für feste Brennstoffe (freistehende
handbetriebene intermittierend brennende Geräte mit langsamer Wärmeabgabe (Speicherfeuerstätten), die
über eine solche Wärmespeicherkapazität verfügen, dass sie über einen längeren Zeitraum nach dem
Erlöschen des Feuers Wärme liefern und abgeben können).
Der Verwendungszweck der Geräte ist Raumheizung in Wohngebäuden. Sie können mit wasserführenden
Bauteilen (als feste Bestandteile des Gerätes mit zu erhitzendem Wasser) zur Warmwasserbereitung der
Zentralheizung ausgestattet sein.
Diese Speicherfeuerstätten können entweder als fertig montiertes Gerät oder als vorgefertigte Einheit
geliefert werden, die aus vorgefertigten Bauteilen besteht, die vor Ort gemäß der angegebenen
Montageanleitung zusammengebaut werden sollen.
Die Geräte können wie angegeben einen oder mehrere der folgenden festen Brennstoffe verfeuern:
 Scheitholz;
 Holzbriketts;
 Holzpellets;
 Braunkohlenbriketts;
 feste mineralische Brennstoffe;
 Torfbriketts.
Dieses Dokument ist nicht anzuwenden für
 mechanisch beschickte Geräte;
 Geräte mit Verbrennungsluftgebläse;
 einmalige Installationen.
Dieses Dokument legt das Verfahren für die Bewertung und Überprüfung der Leistungsbeständigkeit (AVCP)
der Eigenschaften von Raumheizern für feste Brennstoffe fest.

Appareils de chauffage domestiques à combustible solide - Partie 2-5: Appareils à libération lente de chaleur (SHRA)

Le présent document s’applique aux appareils de chauffage à combustible solide à libération lente de
chaleur (SHRA à combustion intermittente alimentés manuellement, dont la capacité de stockage
thermique leur permet de fournir et libérer de la chaleur pendant une durée prolongée après la fin de la
combustion).
L’usage prévu des appareils est le chauffage des locaux dans les bâtiments résidentiels. Ils peuvent être
équipés d’un bouilleur ou d’un échangeur de chaleur (faisant partie intégrante de l’appareil et
contenant de l’eau à chauffer) pour fournir de l’eau chaude aux systèmes de chauffage central.
Ces SHRA peuvent être fournis sous la forme soit d’un appareil assemblé, soit d’une unité conçue au
préalable, constituée d’éléments préfabriqués, destinés à être montés sur le site conformément aux
instructions d’assemblage spécifiées.
Ces appareils peuvent utiliser un ou plusieurs des types de combustibles solides suivants,
comme spécifié :
— bûches de bois ;
— bois compressé non traité ;
— granulés de bois ;
— briquettes de lignite ;
— combustibles minéraux solides ;
— briquettes de tourbe.
Le présent document ne s’applique pas :
— aux appareils à alimentation mécanique ;
— aux appareils dont l’air de combustion est assisté par un ventilateur ;
— aux installations uniques.
Le présent document spécifie des modes opératoires pour l’évaluation et la vérification de la constance
des performances (EVCP) des caractéristiques des SHRA.
