Victorian Government Solar Hot Water Rebate

Are you looking to save money on your energy bills and reduce your carbon emissions? The Victorian Government is offering a rebate of up to $1,000 when you install an eligible solar hot water system. To be eligible for the rebate, you must own the property, have an existing electric or gas hot water system, and use an eligible solar hot water system.

In addition to the solar hot water rebate, you may also be eligible for a VEECs (Victorian Energy Efficiency Certificates) rebate. VEECs are created when a household or business installs an energy-efficient hot water system, and can be traded on the open market. The value of VEECs varies, but it can be used to reduce the upfront cost of a new hot water system.

Why Switch to Heat Pump Hot Water Systems?

Switching to a heat pump hot water system can help you save up to 70% in water heating costs compared to electric or gas hot water systems. Heat pump hot water systems work by extracting heat from the surrounding air and transferring it to the water, using up to 70% less energy than traditional hot water systems.


To be eligible for the Victorian Government’s solar hot water rebate, you must own the property, have an existing electric or gas hot water system, and use an eligible solar hot water system. The system must be installed by a licensed plumber and meet certain efficiency and safety standards.


The iStore comes with a 5-year warranty on the tank and a 2-year warranty on the heat pump unit. This means that if your iStore experiences any defects or malfunctions during this time, we will repair or replace the unit free of charge.

Our warranty covers all parts and labor required for repairs or replacements, and we have a team of trained technicians who can provide fast and efficient service. We understand how important hot water is to your daily life, which is why we strive to resolve any issues as quickly as possible.

In addition to our warranty, we also offer ongoing maintenance and support for your iStore hot water heat pump. Regular maintenance can help to extend the lifespan of your unit and ensure that it operates at maximum efficiency.
