    Overview

    The Enviroflo AR Series Heat Pump is a cutting-edge solution for eco-friendly, efficient, and reliable hot water tailored to meet the demands of Australian homes. Available in 300L and 340L capacities—the largest integrated residential heat pump in Australia—it delivers consistent performance even during peak demand, thanks to its built-in electric element boost. Its lightweight design simplifies installation while its robust construction handles water pressures up to 1000kPa, ensuring durability in harsh climates.

    Harnessing the high-efficiency R290 refrigerant with an ultra-low global warming potential, the system minimizes environmental impact while maximizing energy savings. With compatibility for solar PV systems, it optimizes savings by integrating renewable energy sources. The intelligent controller enhances efficiency, reducing energy use by over 70% compared to standard electric water heaters, with operating modes like ECO, Hybrid, and Vacation to suit your lifestyle.

    Silent operation at just 45dB(A) ensures unobtrusive performance, while features like auto-disinfection prevent legionella growth, and an anti-frost function protects the evaporator in colder conditions. The Wi-Fi module enables seamless control from anywhere, and the system’s ability to operate at off-peak electricity times further reduces costs. For peace of mind, the auto-restart function ensures operation resumes after power outages.

    This heat pump is eligible for Federal Small-Scale Technology Certificates (STCs), making it not only an environmentally conscious choice but also a cost-effective one, thanks to government rebates. With its forward-thinking design, the Enviroflo AR Series delivers dependable, sustainable hot water with minimal environmental impact.
