Rinnai N1600e 58.4 kW External Condensing Gas Water Heater | LPG & Natural Gas

Rinnai N1600e external gas water heater

The Rinnai N1600e 58.4 kW External Condensing Gas Water Heater is a high-capacity commercial continuous-flow water heater designed for applications requiring a reliable supply of hot water without relying on a large storage tank.

Part of the Rinnai N Series, the N1600e combines 58.4 kW output, condensing technology, Low-NOx burner technology, a stainless-steel heat exchanger and a 13:1 turndown ratio. Rinnai specifies hot-water delivery of up to 37 L/min, depending on operating conditions.

The external configuration makes the N1600e particularly useful for professionally designed commercial installations where indoor plant-room space is limited.

58.4 kW Condensing Commercial Water Heater

The Rinnai N1600e is designed for commercial installations where hot-water demand can vary significantly.

Its continuous-flow design heats water as it is required rather than relying on a large volume of stored hot water. The system modulates according to demand, helping provide consistent hot-water delivery across changing usage patterns.

Rinnai specifies the N1600e at 58.4 kW with up to 37 L/min flow under suitable operating conditions.

Up to 37 L/min Hot-Water Flow

The N1600e can provide up to 37 litres of hot water per minute.

Actual flow depends on factors such as:

• Incoming water temperature
• Required outlet temperature
• Water pressure
• Gas supply
• Installation configuration
• Hot-water demand

Rinnai also provides a flow-booster setting for specific conditions. Higher flow should therefore only be specified when the installation meets the manufacturer’s requirements.

Low-NOx Gas Water Heater

The N1600e uses Rinnai Low-NOx burner technology.

Rinnai’s current product information identifies emissions of less than 20 ppm for the N1600e. This makes the product relevant for commercial projects where combustion emissions and applicable environmental requirements are important design considerations.

Stainless-Steel Heat Exchanger

The N1600e uses a stainless-steel heat exchanger designed for demanding commercial hot-water applications.

The stainless-steel heat exchanger works together with the condensing design and modulating burner system to provide efficient heat transfer and controlled hot-water production.

13:1 Turndown Ratio

The Rinnai N Series incorporates a 13:1 turndown ratio.

This allows the water heater to adjust its operation according to changing demand rather than operating continuously at maximum capacity. This is particularly valuable in commercial properties where hot-water requirements can change throughout the day.

LPG and Natural Gas Configurations

The Rinnai N1600e is available in configurations for LPG and Natural Gas.

Select the correct gas configuration for the intended installation. Gas type, supply pressure, conversion requirements and commissioning must be confirmed by the qualified installer before installation.

Where an LPG conversion kit is supplied with the specific configuration sold, the installer should follow the manufacturer’s conversion and commissioning instructions.

External Installation

The N1600e is designed for external installation.

Its outdoor configuration can help preserve valuable internal plant-room space. Rinnai states that N Series appliances can be wall mounted, while cascade-frame installations can be used where multiple units are required.

Installation must comply with the manufacturer’s instructions and the applicable gas, building, ventilation, flue and safety regulations in the destination country.

Cascade Commercial Hot-Water Systems

Multiple Rinnai N1600e units can be configured in a cascade system where a single appliance is insufficient for the required peak hot-water demand.

Cascade systems allow commercial projects to scale hot-water capacity while maintaining a responsive continuous-flow design.

This can be particularly useful for larger hospitality, leisure, healthcare, food-service and industrial applications.

Long Flue-Run Capability

The N Series uses a powerful fan system that provides flexibility when designing the flue arrangement.

Rinnai states that the N1600 can support flue runs of up to 46 metres using the specified Rinnai concentric 80/125 flue configuration, subject to the manufacturer’s installation requirements.

The exact flue design must be confirmed against the installation manual and the configuration being installed.

Commercial Applications

The Rinnai N1600e can be considered for professionally designed commercial hot-water systems including:

• Hotels
• Restaurants
• Bars
• Cafés
• Gyms
• Leisure facilities
• Healthcare facilities
• Schools
• Food production
• Brewing
• Agricultural facilities
• Industrial premises
• Commercial accommodation
• Other high-demand hot-water applications

The correct system size should be determined from the property’s peak hot-water demand, required outlet temperature and incoming water conditions.

Technical Specifications

Technical specifications can vary by gas configuration and installation arrangement. Always check the manufacturer’s current documentation before installation.

Rinnai N1600e vs Rinnai N1300e

The Rinnai N Series provides different capacity options for commercial hot-water applications.

The N1600e provides up to 37 L/min, while the N1300e provides up to 35 L/min. Rinnai lists the N1600e at approximately 29 kg and the N1300e at approximately 28 kg.

For larger projects, multiple units can also be configured in cascade.

Choosing between the N1300e and N1600e should be based on peak hot-water demand, required temperature rise, gas availability and the overall system design.

Professional Installation

The Rinnai N1600e is a commercial gas appliance and must be installed and commissioned by appropriately qualified professionals.

Before ordering, the installer or heating-system designer should confirm:

• Natural Gas or LPG configuration
• Gas supply capacity
• Required gas pressure
• Peak hot-water demand
• Incoming cold-water temperature
• Required hot-water temperature
• Available water pressure
• Flue arrangement
• Condensate requirements
• External installation requirements
• Local regulations
• Whether a cascade system is required

Do not attempt to install, convert or commission the appliance without the appropriate qualifications.
