Rinnai 26L NG Gas Booster Builders 60C Instant Hot Water System B26N60A B26 Energy Efficient Continuous Hot Water Flow High Capacity for Large Home

Frequently Asked Questions

Is the Rinnai 26L Gas Booster suitable for a large Australian home?

Yes, the Rinnai B26N60A is specifically designed for larger homes. It heats water at 26L per minute (raised 25°C), making it capable of supplying hot water to 1–3 bathrooms simultaneously depending on your climate zone. This capacity means you can run multiple taps, showers, or appliances without waiting for hot water or experiencing temperature drops—ideal for family homes across Australia.

How energy efficient is this unit, and will it save me money on gas bills?

The Rinnai B26 achieves a 6.0 star energy rating, one of the highest available for continuous flow gas systems. It only heats water on demand rather than storing it in a tank, which significantly reduces energy waste and running costs. This on-demand heating approach also cuts greenhouse gas emissions, making it an eco-friendly choice for Australian households looking to lower their utility bills.

What's the minimum water flow rate, and will it work with my water-saving shower head?

The unit has a minimum operating flow rate of 1.5L/min, which means it's fully compatible with low-flow shower heads that meet Australian WELS (Water Efficiency Labelling and Standards) requirements. This makes it perfect if you're committed to water conservation while still enjoying reliable hot water pressure throughout your home.

How is the Rinnai B26 delivered, and what's the return policy if I'm not satisfied?

Yarra Supply offers Australia-wide free shipping on the Rinnai 26L Gas Booster, so you won't pay extra for delivery no matter where you are across the country. If you change your mind or the product doesn't meet your expectations, we provide a 30-day returns policy, giving you peace of mind with your purchase. Installation costs and gas line connections are separate and should be arranged with a qualified plumber or gas fitter.

Do I need an electrician to install this, and what power supply does it need?

The Rinnai B26 requires a dedicated AC 240V 50Hz, 10 amp weatherproof power point for operation—this is standard Australian electrical supply. While the power connection is straightforward, you'll need a qualified licensed plumber or gas fitter to handle the water and gas connections, as these are regulated work in Australia. We recommend getting installation quotes from local tradespeople before finalizing your purchase.

What makes the Rinnai B26 better than other continuous flow systems at this price point?

The Rinnai B26 combines several standout features: Japanese engineering for durability, a 15-year warranty on the heat exchanger, Puretemp™ technology for stable and precise temperature control, and compatibility with up to 4 water controllers for multi-bathroom homes. Its compact design (531mm H × 351mm W × 195mm D) allows flexible external installation, and at just 15kg, it's lighter than many competitors. The 6.0 star rating and proven reliability make it excellent value at AUD $1295.

What's the warranty coverage on this Rinnai unit?

The Rinnai B26N60A includes a substantial 15-year warranty on the heat exchanger, which is the core component responsible for heating your water. This extended coverage demonstrates Rinnai's confidence in the product's longevity and gives Australian homeowners long-term protection on their investment.
