The Rheem® Stellar® Mains Pressure Gas Water Heater 160L is one of the most efficient domestic gas storage water heaters available in New Zealand. Operating on Natural Gas only and designed exclusively for outdoor installation, the Stellar® delivers mains pressure hot water to multiple taps simultaneously — making it an ideal choice for homes with more than one bathroom and moderate to high water use.
No electricity required — the Stellar® will continue to work even during a power outage. With its advanced SuperFlue technology, vitreous enamel lining, and innovative styling designed to blend with the external home environment, the Stellar® is a robust, long-lasting, and weather-ready hot water solution for households of 3–6 people.
No Power Required
The Rheem® Stellar® operates entirely on Natural Gas with no electrical connection required — meaning your hot water supply remains uninterrupted even during a power outage. A practical and resilient solution for New Zealand homes.
High Flow Rate for Multi-Bathroom Homes
With a gas consumption rate of 42 MJ/h and mains pressure delivery, the Stellar® is specifically designed for homes with more than one bathroom and moderate to high hot water demand — providing strong, consistent flow to multiple taps simultaneously without pressure loss.
Advanced Stellar® SuperFlue Technology
Rheem’s innovative SuperFlue design pulls gas-heated hot air through the unit twice to maximise combustion efficiency and heat transfer — extracting more energy from every unit of gas and keeping running costs low. The majority of parts are made from recyclable metals.
Vitreous Enamel Lining for Corrosion Resistance
The high-quality vitreous enamel lining protects the inner cylinder from the variety of water qualities found throughout New Zealand — providing outstanding long-term corrosion resistance and extending the life of the unit.
Designed for Outdoor Installation
Engineered exclusively for outdoor installation, the Stellar® features innovative styling that blends with the external home environment — a stylish and weather-ready presence on the outside of your home.
Suitable for All Mains Water Pressures
With a maximum working pressure of 1400 kPa, the Stellar® is compatible with all standard New Zealand mains water pressure conditions — no pressure-reducing valve required in most installations.
Key Features
Mains Pressure Delivery
Delivers mains pressure hot water throughout your home, ensuring strong flow to all taps, showers, and appliances — even when multiple outlets are in use at the same time.
Made in Australia
The Rheem® Stellar® is manufactured in Australia to exacting quality standards, built for long-term reliability in New Zealand’s varied climate conditions.
10-Year Cylinder Warranty
Backed by a 10-year domestic cylinder replacement warranty, the Stellar® 160L is built for lasting peace of mind.
