Water Heating 9 June 2022

The World's First Hydrogen Water Heater

At Rinnai, we believe that we all have a responsibility to protect the planet for our future generations to inherit. It is vital that we are mindful of our impact on the environment, and that we do all we can to make the most of the resources we have. 

As a leader in gas appliances, Rinnai strives to make sustainable improvements across all areas of our business as we hope to shape and influence the future of our industry. With R&D innovation placed at the heart of what we do, we are proud to announce that we have developed the world’s first 100% hydrogen combustion technology for residential water heaters. With 0% carbon emissions it’s a world first and another important step on our journey towards a more renewable future.

This latest breakthrough will be an absolute game changer, both for our business and for the wider gas industry. Ray Ferner, the Managing Director of Rinnai New Zealand, says it will mark the beginning of bringing proven household appliances that can run on 100% renewable gas to market.

"We all need to take action to create a sustainable future. We have been working on the next generation of gas appliances to do our part and give people the safest and best climate control and water heating solutions that run on 100% renewable gas.”

“While there is further work to be done, this is a critical step towards a zero net carbon future and the start of bringing to market proven household gas appliances that can run on totally renewable gas."

We are excited at the prospect of being able to utilise this technology for our current and upcoming projects, to help move New Zealand towards a zero-carbon future.

This is an innovation almost ahead of its time. While we have developed 100% hydrogen combustion technology for water heaters, New Zealand presently does not have the infrastructure to supply 100% hydrogen through the existing pipe network, which means that we will be unable to launch our hydrogen water heaters until the infrastructure is ready. However, we expect to see more progress on this front in the near-future as the Government begins to define a gas transition pathway for New Zealand, with more renewable gas trials expected to commence soon both here and overseas.

Even though we will not see 100% hydrogen water heaters in New Zealand homes just yet, we are thrilled by the potential of this new technology and what this will mean for the future of the industry. When the infrastructure is ready, we will be ready too.
