Hot water systems

Receive discounts when you connect your home

to a new gas or solar hot water system.

Want to get connected to gas or solar hot water?

When you use hot water in your bathroom, kitchen or laundry, you’re not just paying for water. You’re also paying for the energy to heat it. Around 23% of the energy used in an average home is used to heat water, so it pays off to have an efficient hot water system in your home.


With REES, the South Australian Government’s Retailer Energy Efficiency Scheme, you may be eligible for a rebate on a solar, heat pump or gas hot water system and its installation. Working with our REES partner, Trade Services SA, you could save on installing a new hot water system.
