Delete clause J8D3 and insert NSW J8D3 as follows:

(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. 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 spa pool must have—

  1. a cover with a minimum R-Value of 0.05; and
  2. a push button and 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 spa pool having a capacity of 680 L or more.

(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 spa pool must comply with the insulation requirements of J6D9.

Applications
