Our Rinnai Efinity Electric Continuous Water Systems Range

19kW Models (ECF19I50 & ECF19I60): The 19kW Rinnai Efinity provides continuous flow hot water suitable for smaller households, apartments, or installations with moderate hot water demands. Available in 50°C or 60°C maximum temperature configurations, these units deliver approximately 8-10 litres per minute of hot water (depending on incoming water temperature). The ECF19I50 model is ideal for temperate climates and standard household use, whilst the ECF19I60 offers higher temperature output for colder climates or applications requiring hotter water. Both models require 3-phase power connection.

29kW Models (ECF29I50 & ECF29I60): The 29kW Rinnai Efinity delivers higher flow rates for larger households, multi-bathroom properties, or commercial applications. These powerful units provide approximately 12-14 litres per minute of hot water, supporting simultaneous hot water usage at multiple outlets. The ECF29I50 suits most residential applications with 50°C maximum output, whilst the ECF29I60 offers 60°C output for demanding applications, colder climates, or commercial environments. Both require 3-phase electrical supply for operation.

Why Choose Electric Continuous Flow?

Never Run Out of Hot Water: Unlike storage tank systems with finite capacity, continuous flow heaters provide endless hot water on demand. Multiple showers, laundry, and dishwashing can occur simultaneously without depleting a storage tank. Perfect for busy households or commercial environments where hot water demands are unpredictable.

Energy Efficiency Advantages: Electric continuous flow systems only heat water when taps are opened, eliminating the standby energy losses inherent in storage tank heaters that continuously maintain water temperature. This on-demand heating approach typically reduces energy consumption by 20-30% compared to traditional electric storage systems, lowering running costs and environmental impact.

Space-Saving Compact Design: The Efinity's wall-mounted design occupies minimal space compared to bulky storage tank heaters. Ideal for apartments, townhouses, or homes where floor space is valuable. The compact footprint enables installation in laundries, bathrooms, or external locations under cover.

Precise Temperature Control: Choose between 50°C or 60°C maximum outlet temperature based on your specific requirements. The 50°C models suit standard residential applications and provide additional safety benefits by reducing scalding risk. The 60°C models accommodate applications requiring hotter water or installations in colder climates where incoming water temperature is lower.

No Legionella Risk: Continuous flow systems don't store water, eliminating the legionella bacteria growth risk associated with storage tank heaters. Water is heated instantaneously as it flows through the unit, providing fresh, clean hot water every time.

Long Service Life: Without storage tanks subject to corrosion and sediment buildup, continuous flow heaters typically enjoy longer service lives than storage systems. Rinnai's quality engineering and robust construction ensure reliable performance for years.

Understanding 3-Phase Power Requirements

All Rinnai Efinity Electric Continuous Flow models require 3-phase electrical supply. Three-phase power is common in commercial properties, newer residential developments, and many established homes. The higher power capacity of 3-phase supply enables the rapid water heating necessary for continuous flow operation.

If your property currently has single-phase power only, upgrading to 3-phase is often possible but requires assessment and installation by licensed electricians. Contact your electricity provider to discuss 3-phase availability and connection costs. Properties already equipped with 3-phase power can accommodate Efinity systems with appropriate circuit installation by qualified electricians.

Selecting Your Rinnai Efinity Model

Household Size & Usage: For 1-2 bedroom apartments or small households with moderate hot water usage, the 19kW models typically provide adequate flow rates. Larger homes with 3+ bedrooms, multiple bathrooms, or higher simultaneous usage benefit from the 29kW models' greater capacity.

Climate Considerations: Colder climates with lower incoming water temperatures require more energy to heat water to desired temperatures. In these environments, the higher capacity 29kW models or the 60°C temperature option may be preferable to ensure adequate hot water flow rates.

Temperature Requirements: The 50°C models suit most residential applications and provide safe, comfortable hot water temperatures. The 60°C models accommodate specific needs like commercial dishwashing, sanitising applications, or installations where tempering valves will be used to achieve desired outlet temperatures.

Electrical Infrastructure: Verify 3-phase power availability at your property before ordering. Licensed electricians can confirm your electrical capacity and advise on any upgrades required. The 19kW models place lower electrical demand than 29kW units, potentially simplifying installation where electrical capacity is constrained.

Frequently Asked Questions

What is continuous flow hot water?

Continuous flow (also called instantaneous or tankless) hot water heaters heat water on demand as it flows through the unit, rather than storing pre-heated water in a tank. This provides endless hot water without the capacity limitations of storage systems.

Do I need 3-phase power for Rinnai Efinity?

Yes, all Rinnai Efinity Electric Continuous models require 3-phase electrical supply. Three-phase power enables the high electrical load necessary for instant water heating. Many homes and all commercial properties have 3-phase available. Consult a licensed electrician to confirm your property's electrical supply.

What's the difference between 50°C and 60°C models?

The temperature rating indicates maximum outlet water temperature. 50°C models suit most residential applications with safe, comfortable hot water temperatures. 60°C models provide hotter water for colder climates, commercial applications, or where tempering valves will reduce temperature to safe levels.

How much hot water does each model provide?

Flow rates depend on incoming water temperature and desired outlet temperature. Approximately, 19kW models deliver 8-10 litres per minute, whilst 29kW models provide 12-14 litres per minute. Colder incoming water or higher desired temperatures reduce flow rates. Your plumber can calculate expected performance for your specific conditions.

What warranty does Rinnai provide?

Rinnai Efinity systems include comprehensive manufacturer warranty coverage. Warranty terms vary by component and installation type. Full warranty details are provided with each unit. Professional installation by licensed plumbers and electricians is required to maintain warranty validity.
