This document specifies the general specifications, constructional requirements and common test methods 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.
Additional requirements for storage water heaters using vitreous enamel for corrosion protection are specified in EN 12897-2.
