iStore Heat Pumps

Hot water is an essential part of any household and can often be taken for granted; have you ever asked yourself how much your daily showers are costing you? You may not be aware that heating hot water for your home can account for up to a quarter of your home’s electricity costs.  
Enter the iStore Heat Pump. Developed using cutting edge technology, the iStore reduces hot water heating consumption by around two thirds compared to a conventional electric or gas storage system, whilst reducing CO2 emissions by up to 4 tonnes! The iStore offers two main storage units: an 180L which caters for three to four people and the 270L for four to five people and up. This state-of-the-art heat pump has been thoroughly tested in Western Australia’s harsh water and has been proven to stand the test of time.

iStore with solar PV

Your iStore Heat Pump can complement rooftop solar PV exceptionally well, with two or three of your roof top solar PV panels generating more than enough free power from the sun to run the system hot water. Plus, when set on a timer to ensure hot water is made and stored during daylight hours, the ability to cut down on hot water costs is remarkable (as shown in the table below). 


Installing an iStore heat pump can save you up to $1,000 per year on your energy bills. 

How does the iStore work? 

A fan draws in outside air containing energy in the form of heat into the evaporator. The evaporator then turns liquid refrigerant into a gas. From here, the compressor will pressurise the refrigerant into hot gas. The hot gas, which is now inside the condenser coil then heats the water inside a coil-wrapped tank. The refrigerant reverts into a liquid after having heated the water and continues to the evaporator for the whole process to start again. This cycle continues until the desired pre-set target water temperature is achieved. Once hot water is used in the home, the cycle will restart the process over once the temperature in the tank has dropped below 45 °C.
