Why Choose a Rinnai Hot Water System?

Rinnai are best known for their Continuous Flow Gas Hot Water System. Known as the Rinnai Infinity, it is available in a range of sizes and styles. The Infinity is a gas water heater that delivers continuous hot water by heating the water as it passes through the system. It does not store the water in a tank like a traditional system.

You can reduce your energy costs and carbon footprint with a Rinnai Solar Hot Water System. Rinnai offer a range of solar systems including close coupled, flat plate and evacuated tube systems. To ensure a continuous supply of hot water, even after a stretch of cloudy days, Rinnai offer a gas booster as an optional addition.

Rinnai also offer a range of more traditional hot water tanks including gas, electric and heat pump tanks. Gas storage tanks are available in 135L and 170L sizes. Electric storage tanks start at 25L through to a 400L model for large families.
