This European Standard specifies a method for the energy assessment of a domestic hot water system
comprising an external heating boiler of specified minimum output indirectly heating an unvented (closed) hot
water tank of up to 1 500 I. Whilst tanks intended primarily for direct heating are not covered by this European
Standard, it does allow the provision of electric heating elements for auxiliary use.
