Rinnai INFINITY N-Series Condensing Gas Continuous Flow Water Heaters

Engineered for high-performance and maximum efficiency, the Rinnai INFINITY N-Series represents the pinnacle of condensing gas continuous flow water heating technology. Designed specifically for demanding commercial applications and large, high-use New Zealand homes, this trade-quality system ensures you never run out of hot water. Whether you are upgrading your home system or managing a major commercial fit-out, the N-Series delivers unparalleled reliability, low running costs, and premium engineering.

The Rinnai INFINITY N-Series is available in two configurations to suit your installation requirements:

• N56kWe (External Unit): Perfect for space-saving outdoor installations in residential and commercial builds.
• N56kWi (Internal Unit): Ideal for secure indoor utility rooms, requiring dedicated flueing.

Why Choose the Rinnai INFINITY N-Series?

Unlike standard water heaters, the N-Series utilizes advanced condensing technology to capture waste heat from flue gases, preheating the incoming water. This highly efficient heating method significantly reduces gas consumption and operating costs. Built with a full stainless steel heat exchanger and internal piping, this unit is engineered to withstand the rigours of Kiwi plumbing systems while maintaining peak thermal efficiency.

Key Features & Trade Benefits:

• Full Stainless Steel Construction: Premium stainless steel heat exchanger and internal pipework offer superior corrosion resistance and longevity.
• Inverted Burner Technology: Downward-firing burner design dramatically reduces maintenance requirements by eliminating the need for regular burner cleaning, leading to longer service intervals.
• Smart Control System: Includes an inbuilt control panel for effortless parameter adjustments and diagnostics.
• Circulating Ring Main Integration: Features built-in pump connectivity to power and control an external circulating ring main, alongside an integrated temperature sensor for seamless in-series operation.
• Simplified Commissioning: The advanced pre-mix burner requires no manual gas pressure setting, making gas-type conversions exceptionally fast and straightforward.
• Easy Scalability: Simple, low-cost daisy-chain electronic connections allow multiple units to be linked together to meet extreme hot water demands.

Product Suitability & NZ Standards:

• Suitable for mains and medium pressure systems in both commercial and residential applications.
• Water Quality: Hard or acidic water must be treated prior to entering the unit to ensure warranty compliance and system longevity.
• Limitations: Please note these units are not suitable for spa or swimming pool heating, nor are they rated for hydronic central heating applications.

Technical Specifications:

• Hot Water Capacity: Deliveries ranging from 1.5 to 37 litres per minute. Nominal water capacity is 32 litres per minute at a 25°C temperature rise (producing up to 1920 L/h of continuous hot water).
• Gas Type: Available in Natural Gas (NG) or LPG configurations. Please specify your required gas type at the time of purchase.
• Operating Noise: Operates at a low 50-54 dB(A). It is recommended to consider this acoustic profile when positioning the external or internal unit near residential bedrooms.

Installation & Clearances (Internal N56kWi Model):

The internal N56kWi is designed strictly for indoor, flued installations. It is fully compliant with AS/NZS 5601.1 standards for installation in enclosures or cupboard spaces. To ensure easy servicing access for your certifying gasfitter, we recommend a minimum clearance of 600 mm in front of the unit. This clearance can be safely reduced to 50 mm if installed within a dedicated, ventilated cupboard space according to the manufacturer's technical guidelines.
