scope:
This Standard-
(a) applies to electric storage water heaters that do not contain a DRED, and have a demand response interface intended to connect with a DRED;
(b) specifies a set of operational instructions that will meet the requirements of remote agents wishing to control the energy consumption of electric and electric boosted water heaters; and
(c) specifies two alternative methods of connecting the demand response interface to the DRED.
An electric storage water heater (whether using electric resistive heating, heat pump water heating, solar water heating or a combination of these) is covered by this Standard if it has-
(i) a nominal capacity between 10 L and 710 L;
(ii) one or more resistive heating elements and a rated electrical power of 7.2 kW or less; or
(iii) no resistive heating element and a rated electrical power of 2 kW or less.
Heat exchange water heaters meeting the above criteria are also covered by this Standard.
The following water heaters are not covered by this Standard:
(A) Gas water heaters.
(B) Instantaneous water heaters.
(C) Boiling water dispensers.
(D) Steam generators.
(E) Sterilizers.
(F) Urns.
(G) Kettles.
(H) Hot water supply systems intended solely for space heating or for swimming pool, spa pool or industrial process heating.
