Larger hot water systems

All hot water systems over 700 litres require additional documentation in order to have certificates created against them.

Air sourced heat pumps over 425 litres are not eligible for certificates if they are installed after 29 June 2010, unless they were installed under contract before 31 December 2010.

Systems over 700 litres

If you are installing a system with a capacity greater than 700 litres on or after 9 September 2009 you are required by the Small-scale Renewable Energy Scheme (SRES) to submit two statutory declarations to the Clean Energy Regulator prior to assigning or creating STCs.

The statutory declarations must state the following:

  • Statutory declaration 1 (to be completed by owner):  That you as the owner intend for the system to remain installed in its original configuration and location for the life of the system.
  • Statutory declaration 2 (to confirm appropriately sized system): 
    • the model of the solar water heater
    • the volumetric storage capacity of the heater
    • the premises at which the heater is to be installed and used
    • the purposes for which the heater, and the hot water produced by the heater, are to be used
    • that the volumetric storage capacity of the heater is appropriate for the premises at which the heater is to be installed and the purposes for which the heater, and the hot water produced by the heater, are to be used
    • the expertise or experience of the person signing the declaration in relation to a heater of the kind covered by the declaration. (in most cases this will be the installer/supplier).

Download statutory declaration templates from the STC assignment and compliance documentation page.

Your statutory declarations must be witnessed by a person who is licensed or registered by law to witness a statutory declaration.

After the statutory declarations have been signed and witnessed you must send them to the Clean Energy Regulator, either via email or post.  Email is preferred.

  1. Scan the documents and submit via email to retstatdec@cleanenergyregulator.gov.au. All emails must have the owner’s surname and the street number and name in the subject line.

(eg. Douglas – 26 Smith St)

OR

  1. Submit a photocopy of the statutory declaration and your contact details.

You must keep copies of the statutory declarations as they may be requested at any time by the Clean Energy Regulator for the purposes of auditing.

Air-source heat pumps

Under the Act an air source heat pump water heater is defined as a device that uses a vapour compression cycle incorporating a compressor, an evaporator that collects energy from the latent and sensible heat of the atmosphere and a condenser that delivers heat either directly or indirectly to a hot storage container.

Units over 425 litres have additional compliance requirements for certificate registration.

If they are over 700 litres they must complete the statutory declarations. Download the statutory declarations from the STC assignment and compliance documentation page.
