(Main)Water supply - Specification for indirectly heated unvented (closed) storage water heaters
Water supply - Specification for indirectly heated unvented (closed) storage water heaters
EN 12897:2016+A1 specifies the constructional and performance requirements and methods of test for indirectly heated, unvented (closed) storage water heaters of up to 2 000 l volume suitable for connection to a water supply at a pressure between 0,05 MPa and 1,0 MPa (0,5 bar and 10 bar), and fitted with control and safety devices designed to prevent the temperature of the stored drinking water from reaching 95 °C. Whilst storage water heaters intended primarily for direct heating are not covered by this document, it does allow the provision of electric heating elements for auxiliary use.
Wasserversorgung - Bestimmung für mittelbar beheizte, unbelüftete (geschlossene) Speicher-Wassererwärmer
Dieses Dokument legt die Anforderungen an die Konstruktionstechnik und die Leistung und Prüfverfahren für mittelbar (indirekte) beheizte, unbelüftete (geschlossene) Speicher Wassererwärmer bis zu 2 000 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 Temperatur des gespeicherten Trinkwassers 95 °C nicht übersteigt.
Obwohl dieses Dokument keine Speicher Wassererwärmer behandelt, die hauptsächlich für direkte Er-wärmung vorgesehen sind, lässt es die Bereitstellung von elektrischen Heizelementen zu Hilfszwecken zu.
