The waiting game
Lower-powered systems may take considerably longer to recover after the tank has been heavily depleted.
The Power of 4kW
vs. The Competition
Most standard heat pumps operate at 2.0kW–2.8kW and can struggle during peak demand or colder months. iStore delivers high-output heating performance for faster recovery, stronger reliability and dependable hot water.

More heating power means hot water recovers sooner.
Heating capacity directly affects how quickly a heat pump can replace the hot water your household uses. With higher output, iStore can restore tank temperature sooner after showers, baths and other periods of heavy demand.
Faster recovery
Greater heating output puts heat back into the tank faster, helping keep hot water available through periods of high household demand.
High Litres-Per-Hour Output
Hot water that keeps up with busy households.
The iStore converts its heating power into an exceptional litres-per-hour recovery rate. Instead of slowly heating water over an entire day, iStore rapidly generates large volumes of hot water to help keep up with household demand.
- Back-to-back showers
- Busy family mornings
- Laundry and household cleaning
- Large baths and higher hot water demand
According to iStore FAQ data, the high-powered compressor delivers an industry-leading 60 to 80 litres per hour recovery rate, continuously pumping hot water back into the tank.
More Hot Water Over Time
More output, fewer running hours.
Because iStore reheats water faster, it needs less operating time to replace the hot water your household uses. That means stronger recovery performance without relying on long, extended running cycles.
Over the same number of running hours, an iStore can produce 100% more hot water than a 2kW heat pump and 48% more hot water than a 2.8kW heat pump.
100% More Hot Water Than a 2kW System
Over the same operating hours, iStore can produce twice the volume of hot water delivered by a lower-powered 2kW heat pump.
48% More Hot Water Than a 2.8kW System
Compared with a 2.8kW heat pump, iStore can deliver substantially more hot water over the same total run time.
Less Time Spent Recovering
Higher heating output helps restore used hot water faster, reducing the length of each recovery cycle.
Lower Workload for the Same Demand
By producing more hot water per running hour, the system can meet household demand with fewer operating hours over time.
High Output Across the Range
Higher output per litre, right across the range.
iStore delivers an exceptional 14.8 watts of heating capacity per litre across both the 180L and 270L models. This gives iStore a higher heating capacity per litre than many split-system heat pumps, while retaining the convenience and simplicity of an all-in-one system.
The result is rapid reheating for family-sized demand, with dependable performance across Australian operating conditions.
14.8W/L Across Both Models
The 180L and 270L iStore models deliver the same exceptional heating capacity per litre, so households do not sacrifice performance when choosing the tank size that suits them.
Up to 16.34kWh of Stored Energy
By storing hot water at temperatures up to 62°C, the iStore 270L can hold up to 16.34kWh of usable thermal energy for household hot water demand.
More Energy Stored at 62°C
A 270L iStore heated to 62°C stores approximately 600Wh more thermal energy than a comparable 270L system limited to 60°C.
Up to 17L More Delivery Capacity
The higher storage temperature can provide up to 17 litres more usable hot water delivery than competing 270L systems that heat only to 60°C.
The Ultimate Thermal Battery
Turn excess rooftop solar into stored hot water.
If you have a home solar PV system, the iStore can act as a highly efficient and cost-effective thermal storage solution for your home.
Smart Energy Redirection
Instead of exporting excess rooftop solar back to the grid for cents, iStore helps capture that energy and convert it into useful hot water.
Intelligent Built-In Timers
Using the user-friendly digital interface, you can program the iStore to run during peak daytime solar generation windows.
75% to 85% Less Energy
By combining free ambient air temperature with rooftop solar power, iStore can use 75% to 85% less grid electricity than conventional electric water heaters.
Why Power Matters
More heating output can mean shorter run times.
You might think a bigger engine uses more energy, but the opposite can be true here. Because the iStore system heats water faster, it can run for fewer hours than lower-powered competitor systems.
- Shorter run times may reduce wear and tear on components.
- Rapid heating helps maximise peak solar generation windows.
- Strong recovery performance helps keep energy bills low.
