The GR Series operates efficiently in ambient air conditions ranging from -7°C to 45°C, making it ideal for Australia’s varying climate zones. With an innovative controller, it uses more than 70% less energy compared to traditional electric water heaters, offering significant savings on energy consumption. The inclusion of the eco-friendly R290 refrigerant, with an impressively low Global Warming Potential of 0.02, further emphasizes its sustainable design.
Engineered for durability, the GR Series withstands water pressures of up to 1000kPa and features a built-in anti-frost function to protect its evaporator in colder climates. Its multiple operating modes (Standard, ECO, Hybrid, Electric, and Vacation) allow users to tailor performance to their preferences and schedules, including an off-peak operation option for cost-effective use. Additionally, features like auto disinfection and auto restart ensure convenience, safety, and uninterrupted hot water supply during power outages or maintenance.
The system’s eligibility for Federal Small-Scale Technology Certificates (STCs) underlines its high sustainability credentials. These grants help offset upfront costs, making the GR Series an accessible choice for eco-conscious homeowners.
