Rinnai N1300e Water Heater

The Rinnai N1300e Water Heater is a high-performance 47kW external commercial condensing gas water heater designed for businesses that require reliable, efficient and continuous hot-water delivery.

Part of Rinnai’s commercial N Series, the N1300e combines Low NOx burner technology, a stainless-steel primary heat exchanger and a 13:1 turndown ratio with a compact external design.

Rinnai states that the N1300 platform can provide up to 35 litres of hot water per minute, depending on operating conditions. It is designed for commercial applications including hotels, restaurants, commercial kitchens, schools, sports facilities and other premises with substantial hot-water requirements.

Available from Energy Fuel UK for UK commercial projects, single-unit purchases and bulk orders.

Why Choose the Rinnai N1300e Water Heater?

The Rinnai N1300e commercial water heater provides hot water on demand rather than relying solely on a conventional large-volume storage cylinder.

This continuous-flow technology makes the N1300e particularly useful for commercial properties where hot-water demand varies throughout the working day.

Key benefits include:

• 47kW commercial performance
• Up to 35 L/min under suitable conditions
• External installation
• Low NOx burner technology
• Stainless-steel primary heat exchanger
• 13:1 turndown ratio
• Continuous hot-water delivery
• Natural Gas and LPG variants
• Accurate temperature control
• Cascade capability for high-demand installations
• Compact commercial design
• Suitable for single and multi-unit installations

47kW Commercial Continuous-Flow Performance

With approximately 47kW maximum input, the Rinnai N1300e is designed for demanding commercial hot-water installations.

Rather than keeping a large tank of water permanently heated, the appliance produces hot water in response to demand.

This makes it suitable for businesses looking for a modern commercial hot-water solution with the ability to accommodate fluctuating usage.

Ideal Applications for the Rinnai N1300e

The Rinnai N1300e can be considered for a wide range of commercial environments, including:

• Hotels and guest accommodation
• Restaurants
• Commercial kitchens
• Cafés and bars
• Schools and colleges
• Gyms
• Sports clubs
• Leisure centres
• Changing and shower facilities
• Care facilities
• Commercial washrooms
• Food-service operations
• Industrial premises

Final suitability and system sizing should always be determined by an appropriately qualified professional.

External Installation

The N1300e is designed for external installation, making it particularly attractive for businesses where indoor plant-room space is limited.

External installation can free valuable internal space while providing a commercial hot-water solution close to the areas where it is required.

For customers requiring an internally installed model, the corresponding internal Rinnai N Series configuration should be considered instead.

Low NOx Technology

The Rinnai N1300e incorporates Low NOx burner technology, one of the important features of Rinnai’s commercial N Series.

This makes the appliance particularly relevant for businesses replacing older commercial gas water-heating equipment with newer technology.

Stainless-Steel Heat Exchanger

Commercial hot-water equipment may experience substantial daily usage.

The Rinnai N1300e incorporates a stainless-steel primary heat exchanger, supporting durability in demanding commercial environments.

Rinnai identifies its stainless-steel heat exchanger as a core feature of the N Series.

13:1 Turndown Ratio

The N1300e has a 13:1 turndown ratio.

This allows the appliance to modulate its operation according to hot-water demand instead of simply operating at maximum capacity whenever water is required.

For commercial properties with changing demand throughout the day, this provides greater operating flexibility.

Rinnai N1300e Technical Specifications

*Actual hot-water flow depends on inlet temperature, desired outlet temperature, water pressure and installation conditions.

Natural Gas and LPG Options

The Rinnai N1300e platform is available in configurations suitable for Natural Gas and LPG.

Customers should select the correct fuel version for their installation and confirm compatibility with their installer before purchasing.

Cascade Multiple Rinnai N1300e Units

For larger commercial installations, multiple Rinnai N Series appliances can be configured as part of a cascade system.

This means businesses aren’t necessarily limited to the capacity of one appliance.

A professionally designed multi-unit installation can provide significantly greater hot-water capacity for larger hotels, leisure centres and other high-demand facilities.

Rinnai N1300e for Hotels

Hotels can experience substantial simultaneous hot-water demand from guest rooms, kitchens, cleaning operations and other facilities.

A correctly sized continuous-flow system can provide a scalable solution, particularly where multiple units are used to accommodate calculated peak demand.

Rinnai N1300e for Restaurants & Commercial Kitchens

Restaurants and commercial kitchens require reliable hot water throughout operating hours.

The combination of 47kW performance, continuous-flow operation and commercial construction makes the N1300e worth considering for demanding food-service applications.

Rinnai N1300e for Gyms & Leisure Centres

Showers and changing facilities can create periods of substantial peak demand.

Multiple Rinnai N Series appliances can be incorporated into an appropriately designed commercial system when one unit isn’t sufficient for the required flow.
