iStore - Solar Powerd Water Heater


Air to energy, the iStore is designed to maximise the use of your solar power by storing any excess solar energy to then use as hot water generation. Through this technique you can make the most of the Solar PV system making the most cost effective energy storage solution available.

Electric hot water generation is the single largest contributor of household electricty costs, by usnig electric storage you can significatly reduce your heating costs.

Using iStore's technology will greatly reduce your electricity costs while utilising effectively a renewable energy source.

iStore use's a type of technology that converts air into hot water through the method of thermal energy transfer.

design optimal 1
Optimal Design:

The iStore features an external wrap around the heating coil, which provides maximum thermal energy transfer without the need for anti-corrosion connections.

easy install 1
Easy to Install:

Thanks to its light weight and refined design, the iStore is easy and quick to install. Depending on your existing system, it can take up to 2 hours.

low consumption 1
Low Consumption:

The iStore consumes 1000w of energy per hour during the air-to-energy process, which represents 3000 to 4000 watts in total for an average heating cycle of 3-4 hours.

Money and Energy Savings:

Heating water for the home accounts for up to 25% of the total energy usage for the average Australian household. iStore reduces water heating consumption by 2/3, while reducing CO2 emissions by 4 tonnes.

Cost Effective:

Thanks to renewable incentives, an iStore costs under $3000 and could save you up to $950 per year on power bills. That’s a payback period of just 3 years.

How The iStore Works:

1. The fan draws in air that contains heat energy which moves across the evaporator.

2. The liquid refrigerant is turned into a gas by the evaporator.

3. The refrigerant is pressurised by a compressor which turns the refrigerant into a hot gas.

4. The hot gas inside the condenser coil will then heat the water inside the coil-wrapping tank.

5. After heating the water the refrigerant reverts back to a liquid and continues on to the evaporator to begin the process again.

6. The cycle will repeat until the temperature that has been set has been achieved

7. While the water is being used in the home, the cycle will restart once the tank temperature has dropped to below 45 degrees celsius.

Water Heating Cost Comparison:

Hot water heating contributes to up to a quarter of the total electric costs for the average Australian household.

Heat Pump hot water systems reduces hot water heating consumption by two thirds from conventional electric or gas storage systems, while reducing CO2 Emissions by 4 tonnes.

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

    Roland A Joondalup

  • Installation of 2 new 'back to wall' toilets, and a flick mixer tap in the kitchen. John was on time, and gave some good advice about a couple of components. When changing out the old flick mixer and installing the new flick mixer, he even installed some cut-off taps into the lines, without being asked. His work was of a very good standard, and he is a pleasant guy to deal with.

    Approximate cost: $600.00

  • Needed a gas line disconnected and capped and water heater inspected. I called John and he couldn't have been more helpful. We arranged a time and day and he was on time and provided a very thorough and friendly service. Would not hesitate to use again...
