Low Consumption

The iStore consumes approximately 0.5kW (1kW for 280L) of power during the air-to-energy process (average household running cycle is 3 - 4 hours = 1.5 to 2kWh total (3 - 4 kWh total for 280L)).

Money & Energy Savings

For the average Australian household, heating water accounts for up to 30% of the total energy usage. The iStore saves you hundreds while saving the planet!

Did you know?

The energy efficient iStore is fast becoming one of the most popular ways of heating your homes hot water. iStore’s technology has been around for decades. The refrigeration industry has been utilising this incredibly efficient form of producing heating capacity ever since the first refrigerant gas was developed way back in 1928.

Water Heating Cost Comparison

Heating hot water for your home accounts for up to a quarter of your electricity costs for the average Australian household. 

The iStore reduces hot water heating consumption by two thirds from conventional electric or gas storage systems, while reducing CO2 emissions by 4 tonnes. 

Installing an iStore could save you up to $950* per year on your energy bills. 

Here’s how it works

istore 180 cross section

iStore 180L

The iStore utilises an ingenious technology to efficiently transfer thermal energy directly from the surrounding air and into water, without dependence of the sun or fossil fuels to provide an energy source.

1. A fan draws in air, containing heat energy, across the evaporator 

2. The evaporator turns the liquid refrigerant into a gas 

3. The compressor pressurises the refrigerant into a hot gas 

4. The hot gas inside the condenser coil heats the water inside the coil-wrapped tank 

5. The refrigerant reverts back to a liquid after heating the water and continues to the evaporator for the process to start again 

6. The cycle continues until the set target temperature is achieved 

7. As water is used in the home, the cycle will restart once the temperature in the tank has dropped 11 degrees below the target temperature
