Rinnai has announced, after intense verification and testing on existing products, all its commercial water heating units are ready now for hydrogen blends – and N Series units installed since 2019 are also included in futureproofing for the advent of decarbonisation. This means that Rinnai is ‘Hydrogen-ready’ for the proposed initial supply of natural gas and hydrogen blends fed through the gas pipeline infrastructure.
Rinnai also said that multiples of its existing ranges are retro-compatible with future hydrogen blending, these include any N series models installed since 2019,
Rinnai’s Chris Goggin explained: “This is a major announcement for our customers’ installations whether current or planned - it simply means that you are future-proofed. It also means that if you have installed any one of the N Series range since December 2019 these models are also hydrogen ready.
“There are four models in the N Series range: 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 water 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.’
“Decarbonisation is the goal for all of us, but it won’t be achieved by a single product type or energy vector. There will be the requirement for different energy sources whether that be hydrogen, electric or district heat, all will be required to achieve widespread decarbonisation.
Goggins added: “It is not productive for anyone or anybody to be agnostic towards different fuels. We need to respect all technologies and be pragmatic and logical when considering services design within our very diverse building stock.”
Hydrogen has already been successfully supplied to the Keele University campus in the Midlands. HyDeploy, the first project in the UK to blend hydrogen into a natural gas network, began the trial in October 2019 with a 20% blend to 100 homes and 30 university buildings. During the trial customers at Keele used hydrogen blended gas safely in their homes and without the need to make any changes to their existing appliances.
The next phase is at Winlaton, near Gateshead, which makes history by becoming the first public network to receive a 20% hydrogen blend. There are 670 houses in the trial area plus the church, primary school and several businesses which will all receive the hydrogen blend for a period of around 10 months. For those interested in the impact of Industrial clusters please refer to the Hynet program in the northwest where it is expected that over 2 million buildings from Liverpool to Manchester will receive blended hydrogen, in the not-so-distant future.
Rinnai has recently committed to creating a comprehensive information hub dedicated to the subject of hydrogen as a low-carbon energy for the future. The Rinnai Hydrogen Information Hub will be aimed at building services consultants, engineers, specifiers and end-users. It will be online and include webinars plus all requested digital or onsite meetings.
The distribution of hydrogen creates a resolution to the Energy Trilemma questions and the very necessary decarbonisation of the UK energy grid. Hydrogen can be potentially combusted through existing in situ appliances, complete with smart controls and cost-effective hardware and software upgrades as demonstrated by proprietary technology in hot water heating units.
Many countries in Europe and Asia are using the post-pandemic economic regeneration plans to instigate plans to switch to hydrogen as the main fuel source for housing, industry and transport. France has recently announced a €7 billion package to build a carbon-free hydrogen industry and Germany has allocated €9 billion.
Hydrogen is already ‘cost competitive’ in niche applications, according to recent research, with the forecast that it is likely to at least price-match industrial-scale alternatives in less than a decade.
Rinnai is a true global player in the manufacture of domestic and commercial appliances and operates in almost 50 countries. Rinnai is the world’s leading manufacturer of continuous flow hot water systems - it makes and sells 2 million units each year. The range of units can be manifolded to supply, limitless hot water to any site of any size. This means fast, efficient, temperature-controlled water on demand at the point of delivery for textile care operations and less space spent on plant rooms with no or little maintenance as all units are proven to be robust with a long, long working life.
