Water supply - Specification for indirectly heated unvented (closed) storage water heaters
This European Standard specifies the performance requirements and methods of test for indirectly heated, unvented (closed) storage water heaters of up to 1000 l capacity suitable for connection to a water supply at a pressure between 5 Mpa and 100 Mpa (0,5 and 10 bar), and fitted with control and safety devices designed to prevent the operating temperature of the stored drinking water from exceeding 100 °C.
Whilst storage water heaters intended primarily for direct heating are not covered by this standard, it does allow the provision of electric heating elements for auxiliary use.
Wasserversorgung - Bestimmung für mittelbar beheizte, unbelüftete (geschlossene) SpeicherWassererwärmer
Diese Europäische Norm legt die Leistungsanforderungen an und Prüfverfahren für mittelbar beheizte, unbelüftete (geschlossene) Speicher Wassererwärmer bis zu 1 000 l Volumen fest, die für den Anschluss an ein Wasserversorgungssystem bei einem Druck zwischen 0,05 MPa und 1,0 MPa (0,5 bar und 10 bar) geeignet und mit Regel und Sicherheitseinrichtungen ausgerüstet sind, die so ausgelegt sind, dass die Betriebstemperatur des gespeicherten Trinkwassers 100 °C nicht übersteigt.
Obwohl diese Norm keine Speicher Wassererwärmer behandelt, die hauptsächlich für direkte Erwärmung vorgesehen sind, lässt sie die Bereitstellung von elektrischen Heizelementen zu Hilfszwecken zu.
Alimentation en eau - Prescriptions pour réservoirs de stockage d'eau chaude à chauffage indirect sans mise à l'air libre (fermés)
La présente Norme européenne définit les prescriptions de performance et les méthodes d'essai applicables aux préparateurs d'eau chaude sanitaire non ouverts à l'air libre (chauffe-eau fermés) d'une capacité maximale de 1 000 l destinés à être raccordés à un réseau d'alimentation en eau à une pression comprise entre 0,05 MPa et 1,0 MPa (0,05 bar à 1,0 bar), équipés des dispositifs de commande et de sécurité conçus pour éviter que la température de l'eau chaude stockée ne dépasse 100 °C.
Bien que la présente norme ne s'applique pas aux ballons à échangeur, celle-ci permet la mise à disposition d'éléments de chauffe électrique à usage auxiliaire.
