Hot water can be one of the biggest contributors to household energy use. A high-efficiency heat pump can help reduce running costs by using heat from the surrounding air to warm your water, while making better use of your solar generation where suitable.
Reduce hot water energy costs
Use solar more effectively during the day
Suitable for many Australian homes
Quiet, efficient and smart-scheduled operation
Installed by Smart Energy Answers
The iStore 270L Heat Pump is a high-efficiency, all-in-one hot water system designed for Australian homes. It uses advanced air-to-energy technology to heat water efficiently and can be scheduled to better align with household energy use and rooftop solar generation.
A heat pump hot water system works differently to a traditional electric hot water system. Instead of relying purely on an electric element, it draws heat from the surrounding air and transfers that heat into the water tank.
The system captures ambient heat from outside air.
The heat pump uses this captured energy to warm the water in the tank.
Where suitable, the system can run during the day to make better use of rooftop solar generation.
Every household uses hot water differently. Before recommending a system, Smart Energy Answers considers your household size, energy usage, current hot water setup, solar system and available installation space.
You have high hot water usage
You have rooftop solar or are planning to install solar
Your current electric hot water system is expensive to run
You want to reduce grid reliance
You want a more efficient replacement system
You want advice before choosing a product
If your solar system exports excess power during the day, a heat pump can help redirect some of that energy into something your household uses every day: hot water.
Use more of your daytime solar generation
Reduce reliance on grid electricity
Store energy as hot water
Improve the value of your existing solar system
Lower household running costs over time
Think of it as practical energy storage, without the cost of a battery.
Get expert advice on whether a heat pump hot water system is right for your home, solar setup and energy usage.
A heat pump hot water system works by extracting heat from the surrounding air and using it to heat water efficiently. Instead of generating heat directly like a traditional electric system, it transfers heat using advanced compressor technology, helping reduce energy consumption significantly.
Yes. Heat pumps are typically much cheaper to run than conventional electric hot water systems because they use far less electricity to heat water. Many households can reduce hot water energy costs substantially after upgrading.
Absolutely. Heat pumps pair extremely well with solar systems because they can use excess solar energy generated during the day to heat your water, helping you maximise your solar investment and reduce grid usage.
The ideal size depends on your household size, daily hot water usage, and energy goals. Larger families generally require higher-capacity systems to ensure consistent hot water availability.
The iStore 270L is designed for medium to large households and is suitable for many Australian homes. It offers a strong balance of efficiency, storage capacity, and performance for everyday hot water needs.
Savings vary depending on your current system, energy usage, and whether you have solar. Many homeowners can significantly reduce their hot water running costs after switching to a high-efficiency heat pump system.
Yes. In most cases, an existing electric hot water system can be replaced with a heat pump upgrade. Our team can assess your setup and recommend the best replacement option for your home.
Yes. Modern heat pump systems are designed to operate efficiently even in cooler temperatures, making them suitable for a wide range of Australian climates.
Heat pumps are generally quiet during operation and are designed for residential environments. Modern systems like the iStore are engineered to minimise operating noise while maintaining strong performance.
Yes. Smart Energy Answers provides professional heat pump installation services, including system recommendations, installation, and support to help ensure a smooth upgrade experience.
