Example—par (d)
a low energy electric water heater
Note An example is part of the regulation, is not exhaustive and may extend, but does not limit, the meaning of the provision in which it appears (see Legislation Act, s 126 and s 132).
(2) However, this section does not apply if—
(a) the water heater—
(i) consists of solid fuel-burning equipment; and
(ii) is installed in a hot-water system in a class 1 building located in an area of non-urban land; or
(b) the water heater—
(i) is an electric water heater; and
(ii) is replacing, under warranty, a water heater in a new class 1 building; or
(c) the water heater is installed for use during construction of the building and is removed when the work is completed.
(3) In this section:
AS 4013 means Australian Standard 4013 ( Domestic solid fuel burning appliances—method for determination of flue gas emission ), as in force from time to time.
AS 4552 means Australian Standard AS 4552 ( Gas fired water heaters for hot water supply and/or central heating ), as in force from time to time.
AS/NZS 2712 means Australian and New Zealand Standard AS/NZS 2712 ( Solar and heat pump water heaters—design and construction ), as in force from time to time.
AS/NZS 4234 means Australian and New Zealand Standard AS/NZS 4234 ( Heated water systems—calculation of energy consumption ), as in force from time to time.
climate zone 3 means climate zone 3 as set out in the register of solar water heaters kept under the Renewable Energy (Electricity) Regulations 2001 (Cwlth).
climate zone 4 means climate zone 4 as set out in the register of solar water heaters kept under the Renewable Energy (Electricity) Regulations 2001 (Cwlth).
"fuel-burning equipment" means a furnace, boiler, fireplace, oven, retort, incinerator, internal-combustion engine, chimney or any other apparatus, device, mechanism or structure, in the operation of which combustible material is, or is intended to be, used or that is, or is intended to be, used in relation to the burning of combustible material.
new class 1 building means a class 1 building for which a certificate of occupancy for the whole building has not been issued under the Building Act 2004 (except a building completed before 2000), and includes a building built to replace demolished premises.
"non-urban land "means—
(a) territory land in 1 of the following zones under the territory plan:
(i) broadacre zone;
(ii) rural zone;
(iii) hills, ridges and buffer areas zone;

(i) an urban area; or
(ii) the Central National Area.
"renewable energy certificate"—see the Renewable Energy (Electricity) Act 2000 (Cwlth), section 5 (1).
"solid fuel-burning equipment" means fuel-burning equipment that is designed to burn hard wood, soft wood or briquettes and to which AS 4013 applies.
2.4 Water heater—determination of other water heaters
(1) The Minister may determine a water heater for section 2.3 (1) (d) if satisfied that—
(a) the greenhouse gas emissions associated with the water heater are not more than the greenhouse gas emissions associated with the operation of any of the water heaters mentioned in section 2.3 (1) (a) to (c); or
(b) the water heater is required to enable the hot-water system in which it is to be installed to operate effectively and it is not reasonable to require the hot-water system to be altered in another way.
(2) A determination is a notifiable instrument.
Note A notifiable instrument must be notified under the Legislation Act .
2.5 Water heater—frost protection standard
A person who installs a heat pump water heater or solar water heater in a hot-water system must ensure that the hot-water system is frost protected to enable it to function at temperatures that can reasonably be expected in the ACT.
2.6 Hot-water system—water flow performance standard
(1) A person who installs a water heater in a hot-water system in a class 1 building, or replaces a water heater in a hot-water system in a completed existing class 1 building, must ensure that each shower fixture outlet connected to the hot-water system has a flow capacity not greater than the capacity mentioned in section 16E (1) (a).
(2) A shower fixture outlet is taken to comply with subsection (1) if it is connected to a shower head, flow controller or flow restrictor that—
(a) achieves a minimum water rating of 3 stars in accordance with the WELS standard for the shower head, flow controller or flow restrictor; and
(b) carries a mark certifying that the shower head, flow controller or flow restrictor complies with the plumbing code.
(3) This section does not apply to a hot-water system servicing a class 1 building that is not connected to a water service.
