iStore 180L Heat Pump

A heat pump hot water system uses electricity to move heat from the surrounding air into the water tank, rather than generating heat directly with an element. This makes it around three times more efficient than a conventional electric hot water system.

A fan draws in ambient air and a refrigerant cycle transfers that heat into the storage tank — much like a refrigerator running in reverse. It uses far less electricity than a standard electric system, especially in Queensland's warm climate.

For most Queensland homes, yes. Heat pumps use up to 70% less electricity than standard electric systems, qualify for government STC rebates, and pair well with solar — so the higher upfront cost is usually recovered through lower power bills.

A quality heat pump hot water system typically lasts around 10–15 years with regular servicing, and the tank is usually covered by a manufacturer warranty.

Yes. Small-scale Technology Certificates (STCs) reduce the upfront cost of an eligible heat pump hot water system, and SunCity Hot Water handles the rebate paperwork for you.

The cost of a new hot water system depends on the type and size. Electric storage systems are the most affordable upfront, while heat pump and solar systems cost more but save on running costs and may qualify for rebates.
