Rinnai Infinity EF250 External
A new generation of continuous flow water heater
Temperature controlled continuous flow gas hot water system for external applications. Factory preset to 55 °C.
• High efficiency (95%)
• Lower gas emissions (due to a secondary heat exchanger)
• Subsequent savings (water is preheated so doesn't use as much energy)
RRP $3,059
Suitable for
• Commercial and domestic external applications
• Mains and low pressure systems
• Solar installations as a gas boost
Hard or acidic water will need to be treated in order to use this product.
Gas type
Available for Natural Gas or LPG. Specify gas type at time of purchase.
