Part J8 Heated water supply and swimming pool and spa pool plant

Introduction to this Part

This Part contains Deemed-to-Satisfy Provisions for compliance with Part J1. It sets out provisions for ensuring water heaters, swimming pool and spa heaters and pump systems use energy efficiently.

Notes

From 1 May 2023 to 30 September 2023 Section J of NCC 2019 Volume One Amendment 1 may apply instead of Section J of NCC 2022 Volume One. From 1 October 2023 Section J of NCC 2022 Volume One applies.

Notes: New South Wales Section J Energy Efficiency

  1. For a Class 2 building or a Class 4 part of a building, where a relevant development consent or an application for a complying development certificate requires compliance with a BASIX Single Dwelling or Multi Dwelling Certificate issued under Version 3.0 or earlier, NSW Section J of NCC 2019 Volume One Amendment 1 applies.
  2. For a Class 2 building or a Class 4 part of a building, where a relevant development consent or an application for a complying development certificate requires compliance with a BASIX Single Dwelling or Multi Dwelling Certificate issued under Version 4.0 or later, Section J of NCC 2022 Volume One applies.
  3. For a Class 2 building or a Class 4 part of a building, where a relevant development consent or an application for a complying development certificate requires compliance with a BASIX Alterations and Additions Certificate, NSW Section J of NCC 2019 Volume One Amendment 1 applies.
  4. For a Class 3 building or Class 5 to 9 building:
    1. From 1 May 2023 to 30 September 2023 NSW Section J of NCC 2019 Volume One Amendment 1 may apply instead of Section J of NCC 2022 Volume One.
    2. From 1 October 2023 Section J of NCC 2022 Volume One applies.

(1) Heating for a swimming pool must be by—

  1. a solar heater; or
  2. a heater using reclaimed heat from another process such as reject heat from a refrigeration plant; or
  3. a geothermal heater; or
  4. a gas heater that—
    1. if rated to consume 500 MJ/hour or less, achieves a minimum gross thermal efficiency of 86%; or
    2. if rated to consume more than 500 MJ/hour, achieves a minimum gross thermal efficiency of 90%; or
  5. a heat pump; or
  6. a combination of (a) to (e).

(2) Where some or all of the heating required by (1) is by a gas heater or a heat pump, the swimming pool must have—

  1. a cover with a minimum R-Value of 0.05; and
  2. a time switch to control the operation of the heater.

(3) A time switch must be provided to control the operation of a circulation pump for a swimming pool.

(4) Where required, a time switch must be capable of switching electric power on and off at variable pre-programmed times and on variable pre-programmed days.

(5) Pipework carrying heated or chilled water for a swimming pool must comply with the insulation requirements of J6D9.

(6) For the purpose of J8D3, a swimming pool does not include a spa pool.
