Rinnai N series hot-water heating units hydrogen ready – and now UKCA certified

Products awarded new post-Brexit conformity mark ahead of January deadline

Rinnai’s N Series range of hot-water heating units and systems are now fully certified to the new UKCA standard, the successor to the European Union’s CE mark.

UK Conformity Assessed (UKCA) marking indicates conformity with the applicable requirements for products sold within Britain.

UKCA marking became mandatory at the end of the Brexit transition period, although the CE mark continues to be accepted as a valid alternative until 1 January 2022.

This news closely follows the announcement by Rinnai that, after an extensive testing and verification process, its N Series product range is ready for the proposed initial supply of natural gas and hydrogen blends set to be fed through the existing gas infrastructure.

All Rinnai units are guaranteed to provide temperature-accurate hot-water flows, as long as fuel and water connections are constant.

Multiples of Rinnai’s existing ranges are retrospectively compatible with future hydrogen blending, including all N-series models already installed in the UK.

The Rinnai Sensei N Series offers a more compact, enhanced combustion design that is easier to install, has superior operational performance, and is easy to service. All are accompanied by extended warranties.

The four models are:
● N1600i, giving 954 litres per hour
● N1600e (external) giving 954 litres per hour (at 50°C).
● N1300i, giving 775 litres per hour
● N1300e, giving 775 litres per hour of temperature-controlled hot water at 50°C.

The two 1600s have load profiles of XXL, while the 1300s are load profile XL; all are water-efficiency class A rated.

The entire range is low-NOx, and the future-proofed continuous flow water heater uses Rinnai’s advanced burner technology with a 13:1turn-down ratio with extremely quiet operation.

Integral controls enable the water heater to achieve high efficiencies because of advanced burner control and high modulation ranges.
