SPASA Heating Submission supported by Australian Building Codes Board

Tuesday, 09 April, 2013

The Australian Building Codes Board Committee has considered and supported SPASA's submission to amend clause 3.12.57 of the Building Code of Australia to allow additional types of heating for swimming pools to be included in the public comment draft of Volume Two (Residential) of the National Construction Code 2014.


In October 2012, a number of Private Certifiers in NSW and Queensland were interpreting the Heating Provisions within the Building Code of Australia stating that "Heat Pumps and Gas Heaters were no longer an approved form of heating for domestics swimming pools due to the fact that the Building code of Australia Volume 2 (for class 1 and 10 buildings) as per sect (a) which stated heating for a swimming pool other than a spa pool must be by a solar heater not boosted by electric resistance heating."

This interpretation was being picked up by other Private Certifiers across other parts of Australia and was causing significant confusion and concern amongst the industry.

What the amendment to 3.12.57 means

Whilst the Australian Building Codes Board Committee has supported the below amendments they are still required as part of their charter to seek comment via a public consultation phase. The Public Comment Draft will be available at when it is released in June 2013. Members are encouraged to participate in this process at that time.


Part would read:

NCC Volume Two - Heating and pumping of a swimming pool or spa pool:

  1. Heating for a swimming pool or a spa pool (excluding portable spas) must be by:

    1. a solar heater not boosted by electric resistance heating; or

    2. a heater using reclaimed energy; or

    3. a gas heater; or

    4. a heat pump; or

    5. a combination of 2 or more of (i), (ii), (iii) and (iv)

  2. Where some or all of the heating required by (a) is by a gas heater or a heat pump, the swimming pool or spa pool (excluding portable spa) must have:

    1. a cover other than when located in a conditioned space; and

    2. a time switch to control the operation of the heater.

In essence, Clause in Volume Two National Construction Code will reflect the exact wording in Part J7.3 of Volume One.
