iStore - Air to Energy

iStore Air to Energy technology drastically reduces your electricity costs, especially when combined with a solar PV system, helping you make the most of it. Utilising thermal energy, the iStore stores the excess solar energy generated by your solar panels and converts it into hot water for your home. 

The iStore is one of the most efficient and affordable energy storage alternatives on the market. In fact, the iStore’s dynamic, efficient system can reduce your water heating costs by up to 70%.

An iStore enables you to:

  • Make the most of your solar PV system
  • Receive STCs (Small-scale Technology Certificates)
  • Generate hot water energy all year round

Heating water for the home accounts for up to 25% of the total energy usage for the average Australian household. iStore is a cost-effective, reliable thermal storage solution which reduces water heating consumption by 2/3 and CO₂ emissions by 4 tonnes. Installing an iStore could save you up to $1,000 per year on your energy bills.*
