J5.9 Space heating

ACT Appendix
(a) A heater used for air-conditioning or as part of an air-conditioning system must be—

(i) a solar heater; or
(ii) a gas heater; or
(iii) a heat pump heater; or
(iv) a heater using reclaimed heat from another process such as reject heat from a refrigeration plant; or
(v) an electric heater if—

(A) the heating capacity is not more than—

(aa) 10 W/m2 of the floor area of the conditioned space in climate zone 1; or
(bb) 40 W/m2 of the floor area of the conditioned space in climate zone 2; or
(cc) the value specified in Table J5.9 where reticulated gas is not available at the allotment boundary; or

(B) the annual energy consumption for heating is not more than 15 kWh/m2 of the floor area of the conditioned space in climate zones 1, 2, 3, 4 and 5; or
(C) the in-duct heater complies with J5.2(a)(ii)(C); or

(vi) any combination of (i) to (v).

(b) An electric heater may be used for heating a bathroom in a Class 2, 3, 9a or 9c building if the heating capacity is not more than 1.2 kW and the heater has a timer.
(c) A fixed heating or cooling appliance that moderates the temperature of an outdoor space must be configured to automatically shut down when—

(i) there are no occupants in the space served; or
(ii) a period of one hour has elapsed since the last activation of the heater; or
(iii) the space served has reached the design temperature.

(d) A gas water heater, that is used as part of an air-conditioning system, must—

(i) if rated to consume 500 MJ/hour of gas or less, achieve a minimum gross thermal efficiency of 86%; or
(ii) if rated to consume more than 500 MJ/hour of gas, achieve a minimum gross thermal efficiency of 90%.
