Water supply - Specification for indirectly heated unvented (closed) storage water heaters

active, Most Current
Organization: NEN
Publication Date: 1 February 2020
Status: active
Page Count: 38
ICS Code (Water heating equipment): 91.140.65
scope:

This document 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.
