(Main)Gas-fired instantaneous water heaters for the production of domestic hot water
Gas-fired instantaneous water heaters for the production of domestic hot water
This European Standard defines the specifications and test methods concerning the construction, safety, rational use of energy and fitness for purpose, and also the classification and marking of gas-fired instantaneous water heaters for sanitary uses, hereafter called “water heaters”.
This European Standard applies to water heaters:
- of types AAS, B11, B11BS, B12, B12BS, B13, B13BS, B14, B22, B23, B32, B33, B44, B52, B53, C11, C12, C13, C21, C22, C23, C32, C33, C42, C43, C52, C53, C62, C63, C72, C73, C82and C83 according to CEN/TR 1749;
- fitted with atmospheric burners;
- equipped with atmospheric burners assisted by a fan for the supply of combustion air or evacuation of combustion products or fully premix burners;
- using one or more combustible gases corresponding to the three gas families and at the pressures stated in accordance to EN 437;
- of nominal heat input not exceeding 70 kW;
- with an ignition burner or with direct ignition of the main burner.
In this European Standard, the heat inputs are expressed in relation to the net calorific value (Hi).
This European Standard does not contain all the requirements necessary for:
- boiling water appliances;
- appliances intended to be connected to a mechanical means of evacuating the combustion products;
- appliances which fulfil a dual role of space heating and heating water for sanitary use;
- appliances making use of the heat of condensation of the water contained in the combustion products;
- water heaters of types B21, B31, B41, B42, B43 and B51.
This European Standard only covers water heaters where the fan, if any, is an integral part of the appliance.
This European Standard:
- does not apply to appliances not intended to be connected to a flue when they are not fitted with an atmosphere sensing device;
- takes account of the information given in Technical Report CEN/CR 1472:1994 with respect to marking.
Type B appliances should be with a combustion products discharge safety device to comply with essential requirement 3.4.3 of the Gas Appliances Directive 2009/142/EC. In this European Standard, the appliance is identified as type B11BS.
Appliances intended to be installed outdoors or in a room separate from inhabited rooms and provided with appropriate ventilation are not required to have this combustion products discharge safety device but, in this case, appropriate warnings on the packaging, and in the instructions should clearly define the limited authorized use for this type of appliance. In this European Standard, the appliance is identified as type B11.
The main symbols used in this European Standard are summarized in Annex F.
Gasbeheizte Durchlauf-Wasserheizer für den sanitären Gebrauch
Dieses Dokument legt die Spezifikationen und Prüfmethoden sowie die Klassifizierung, Kennzeichnung und Energieeffizienzkennzeichnung von gasbeheizten Durchlauf Wasserheizern für den sanitären Gebrauch, im Folgenden als „Wasserheizer“ bezeichnet, fest.
Dieses Dokument gilt für Wasserheizer:
- von Typ A, B und C, wie jeweils in den entsprechenden Abschnitten beschrieben;
ANMERKUNG Für weitere Informationen zur Konfiguration der Gerätearten siehe EN 1749:2020.
- die in Übereinstimmung mit EN 437:2021 ein oder mehrere brennbare Gase der drei Gasfamilien und die angegebenen Drücke verwenden;
- mit einer Nennwärmebelastung bis höchstens 77 kW basierend auf dem Brennwert (GCV, en: gross calorific value);
- mit einem Zündbrenner oder direkter Zündung des Hauptbrenners.
In diesem Dokument werden die Wärmebelastungen auf den Heizwert (Hi) bezogen.
Dieses Dokument umfasst nicht alle notwendigen Anforderungen für:
- Kochwassergeräte;
- Geräte, die für den Anschluss an eine mechanische Abführung der Abgase vorgesehen sind;
- Geräte, die eine Doppelfunktion von Raumheizern und Warmwasserbereitung für den sanitären Gebrauch erfüllen.
Dieses Dokument behandelt nur Wasserheizer, bei denen, falls vorhanden, das Gebläse ein integraler Bestandteil des Gerätes ist.
Dieses Dokument ist nicht für die Abdeckung von Geräten vorgesehen, die dafür ausgelegt und gebaut wurden, Gas mit toxischen Komponenten zu verbrennen.
Appareils de production instantanée d'eau chaude pour usages sanitaires utilisant les combustibles gazeux
Le présent document définit les spécifications et méthodes d'essais, ainsi que la classification, le marquage et l'étiquetage énergétique des appareils de production instantanée d'eau chaude pour usages sanitaires utilisant les combustibles gazeux, désignés ci-après « chauffe-eau ».
Le présent document s'applique aux chauffe-eau :
- de types A, B et C décrits aux articles appropriés;
NOTE Pour plus d'informations sur la configuration de ces types d'appareils, voir l'EN 1749:2020.
- utilisant un ou plusieurs combustibles gazeux correspondant aux trois familles de gaz et aux pressions indiquées conformément à l'EN 437:2021 ;
- de débit calorifique nominal inférieur à 77 kW, sur la base du pouvoir calorifique supérieur (PCS) ;
- avec brûleur d'allumage ou à allumage direct du brûleur principal.
Dans le présent document, les débits calorifiques sont exprimés par rapport au pouvoir calorifique inférieur (PCI).
Le présent document ne contient pas toutes les exigences nécessaires pour :
- les appareils à eau bouillante ;
- les appareils destinés à être connectés à des moyens mécaniques d'évacuation des produits de combustion ;
- les appareils qui remplissent une double fonction de chauffage des locaux et de production d'eau chaude sanitaire.
Le présent document couvre uniquement les chauffe-eau où le ventilateur, le cas échéant, fait partie intégrante de l'appareil.
Le présent document n'a pas pour objet de couvrir les appareils conçus et construits pour brûler du gaz contenant des composants toxiques.
