Say goodbye to huge energy bills from your old hot water system. The iStore Heat Pump is the smart, modern solution designed for Australian homes. It works like a reverse-cycle air conditioner, pulling free heat from the air around it to warm your water. This method uses far less electricity than traditional heaters, instantly cutting one of your biggest household costs. It’s smart, efficient, and great for the planet.
Cut Hot Water Bills by Up to 70%: Hot water is usually around a quarter of your home’s energy use. The iStore is up to 4 times more efficient than standard electric systems, resulting in hundreds of dollars in savings every year.
Maximise Your Solar Savings: If you have solar panels, the iStore acts like a thermal battery. We program it to run during the day, using your free excess solar power to heat your water, ensuring zero wastage and maximum financial return on your rooftop investment.
Earn Government Rebates (STCs): Because the iStore is highly energy-efficient, it qualifies for government incentives (Small-scale Technology Certificates or STCs). We help you claim these rebates, which significantly reduce the upfront cost, making the switch even easier.
The iStore is more than just a water heater; it’s an energy saver and a solar companion. By capturing natural heat, you get reliable hot water while slashing power consumption and putting your solar energy to the best possible use.

Think of it as a refrigerator working in reverse. Instead of pushing heat out of an enclosed space (like your fridge), a heat pump draws warm air from the environment and uses a small amount of electricity to amplify that heat.
It then transfers the highly amplified heat into the water tank. Because it only moves existing heat rather than generating it from scratch, it is vastly more efficient than traditional electric or gas heating elements.

Modern heat pump systems are very quiet. They typically operate at a sound level similar to a modern air conditioner or dishwasher—around 45 to 55 decibels. Since the unit is usually installed outside, the low humming sound is generally not noticeable inside the home. Most units also have smart timers, allowing you to schedule operation for the middle of the day when household noise is higher.
Heat pumps are eco-friendly for two main reasons:
Lower Electricity Use: They use significantly less electricity than old systems, which reduces the demand on power stations and lowers greenhouse gas emissions.
Renewable Source: They use the ambient heat energy from the air, which is a limitless, renewable resource. When paired with solar, they run entirely on clean energy, virtually eliminating the carbon footprint from your water heating.
The iStore Heat Pump can reduce your hot water energy consumption by up to 70% compared to a traditional electric storage system. This is because it uses heat from the air (which is free) instead of constantly drawing high power from the grid. For the average Australian household, this can translate into savings of up to $1,000 per year on your power bill, making your investment pay for itself very quickly.

Yes. Heat pumps are an ideal replacement for both gas and electric systems. They use the same water connections as your old tank and only require a simple electrical connection. Installing a heat pump means you can often decommission your old gas line entirely, simplifying your utilities and reducing potential supply charges.
A Heat Pump is designed to be the perfect partner for your solar system. COYCO can program the unit’s built-in timer to run during the middle of the day, specifically when your solar panels are generating the most excess electricity. This means you are heating your water for free using your own solar energy, maximising your financial return on solar and minimising what you send back to the grid.
Heat pump units are typically installed outdoors. They need a well-ventilated area that can provide easy access to ambient air, as this is their heat source. They can be placed on the ground, but require a suitable flat surface and enough clear space around them (usually 300mm–600mm) to ensure good airflow for maximum efficiency.
Yes, absolutely. The iStore is designed to work across a wide range of Australian climates. It extracts heat from the surrounding air, and even air that feels cold still contains enough heat energy to warm your water. On extremely cold days, the unit has an automatic defrost function and a backup electric element (Hybrid Mode) that can provide a boost, ensuring you always have hot water when you need it.
Maintenance is minimal. We recommend you perform a simple test of the Pressure and Temperature Relief (PTR) valve every 6 months. Beyond that, the iStore requires a professional service by a licensed plumber every 2-5 years, depending on your local water quality, to inspect and replace the system’s sacrificial anode. With proper care, the iStore has an expected lifespan of 10 to 15 years.
