Rinnai introduced the Sensei N series

Rinnai is introducing the Sensei N Series to the UK marketplace, as the new generation of maximum quality and reliability in hot water heating delivery.

The Sensei N series

The new Rinnai Sensei N Series water heater range offers a new and more compact and enhanced combustion design that allows for easier installation and enhanced operational performance together with increased levels of serviceability.

All components in the range are designed and manufactured by Rinnai, and this ensures maximum quality and reliability from the industry leader in commercial continuous flow water heating products and systems. 

The Rinnai Sensei N Series is one of the first ever continuous flow hot water heating unit manufactured with stainless steel heat exchangers to be available in the UK - this gives a greatly extended working life at optimum performance to each of the four models in the range. Added to this is the Sensei N Series market leading extended warranties.

The four models are: the N1600i giving 954 litres per hour; the N1600e (external) also giving 954 litres per hour (at 50 degrees); the N1300i giving 775 litres per hour and the N1300e also giving 775 litres per hours of temperature controlled at 50 degrees. The two 1600s have load profiles of XXL and are water efficiency class A rated, while the 1300s are load profile XL and are also water efficiency class A rated.

Other features include: 

  • flue up to 30+ metres for concentric
  • Turbo Fan
  • Built-in controller as standard on both internal and external models
  • Cascade Cable assembly allows up to 24 water heaters to be connected and function as one total and complete system Any number of N-series Rinnai water heaters can be manifolded together enabling the largest capacities on the market.
  • Built in flue damper
  • Air inlet filter
  • Frost Protection – minus 15°C on the internal versions and minus 20 °C on the external versions
  • New PCB Design
  • Controller as standard – Lockable, set up of appliance, Temperature set up to 75°C
  • Maintenance Monitor for engineers

Rinnai manufactures over 2 million hot water heating units each year and so can offer advantageous cost savings for installers and end users. The N Series are probably the most competitively priced type of their kind currently available to the UK sector.

All the range are also low-NOx and the Sensei N Series utilises Rinnai’s patented advanced burner technology with a 13-1 turn down ratio – the largest on the market – with extremely quiet operation. Integral controls on the units enable the water heater to achieve high efficiencies because of advanced burner control and high modulation ranges. 

In reducing Legionella proliferation, Rinnai has developed additional ‘SMART’ controls for secondary return DHW systems in the form of an advanced temperature control system which allows for safe running of water at 42°C core temperature during the day and 60°C overnight.  

The advanced burner controls with the Sensei N Series models ensure that all the appliances are well ahead of the NOx requirements set within ErP.  The current level of permissible NOx set by ErP is 56 mg/Kwh.  The Sensei N Series range have been third-party tested at 28 mg/Kwh making them one of the greenest water heating appliances available.

As the units do not incorporate storage their ‘green credentials’ are further recognised by BREEAM and score additional credits under the building regulations.
