    Overview

    Designed for modern Australian households, the Envirosun HP Plus Heat Pump Water Heater combines advanced engineering, smart functionality, and sustainable operation into one efficient system. Built with inverter technology and powered by the environmentally friendly R290 natural refrigerant, the HP Plus delivers rapid water heating while significantly reducing energy use and environmental impact.

    Its versatility shines through two capacity options—200L and 330L—making it ideal for both small households and large families. The triple full-length anode protection ensures a longer lifespan by defending against corrosion, while the microchannel condenser boosts heat transfer efficiency. Quiet by design, the HP Plus operates at just 42dBA, ensuring a peaceful home environment even when installed close to living spaces.

    Users can tailor their hot water experience through four intelligent operating modes, including Eco for energy savings and Mute for silent overnight heating. An intuitive TFT LCD screen simplifies operation, allowing users to adjust settings with ease. The unit is also frost and legionella resistant, making it suitable for varied Australian climates.

    Smart integration with solar PV systems allows households to maximise energy savings by heating water when solar generation is at its peak. Backed by strong performance credentials and exceptional STC ratings, the Envirosun HP Plus stands out as a top choice in energy-efficient water heating. Whether you’re upgrading from an older system or designing a new build, the HP Plus brings together reliability, innovation, and sustainability, delivering dependable hot water all year round.
