Hot Water Rebates

Check your eligibility for Hot Water System Rebates


Retailer Energy Efficiency Scheme (REES):  REES is a SA Government energy efficiency scheme that assists households and businesses to move towards more energy efficient choices. It does so by establishing energy efficiency and audit targets to be met by electricity and gas retailers. The REES is designed to make energy saving improvements more affordable, contribute to the reduction of greenhouse gases and encourage investment and employment in South Australia.

Small Scale Technology Certificates (STC): STC’s are made available through a Federal Government scheme called the Small-scale Renewable Energy Scheme. The certificates/rebates created are based on location, installation date and amount of displaced MWh the solar or heat pump hot water has over the course of its lifetime (up to 10 years).

Australian Gas Networks (AGN): AGN owns the natural gas distribution network in South Australia. To incentivise customers to connect to the natural gas network they not only offer rebates for converting an appliance (hot water, heating, cooking, BBQ), but they are also offering an additional new connection bonus to help reduce the cost of the initial connection from the meter to the home.

RETICULATED GAS NETWORK: Available for both natural and LPG, reticulated gas is the distribution of gas via a network of pipes, moving gas from a storage location that services a multitude of customers. For example, if there is a meter at the property then you are connected to the mains (reticulated) gas supply.

CLASS 1: Single detached dwelling or two or more attached dwellings separated by a fire-resistant wall (including a maisonette, row house, townhouse, and single-storey flats or units).

CLASS 2: Multi-storey building containing two or more sole-occupancy units, where each is a separate dwelling (e.g. apartment or flat in a multi-storey building).

All rebate & installation prices are subject to site inspection & changes to government incentives – Contact us today to determine your eligibility.
REES: Sites eligible for the REES rebate are those that have not replaced the hot water system under REES before, are in an existing Class 1 home, or in a new or existing Class 2 multi storey apartment building. Class 1, existing homes, connected to a reticulated gas supply are ineligible. These offers are only available on supply and installation of the system by GM Hotwater or their accredited representative and all REES credits created under these offers must be assigned to their nominated energy retailer.
