PRODUCTS & SERVICES Products of the month Rinnai to set up hydrogen information hub for consultants, specifiers and end-users The hub will be available online and will offer webinars and digital or onsite meetings R innai, manufacturer of hot water heating units and delivery systems for all commercial sites, is to create 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 available online and will offer webinars and digital or onsite meetings. Rinnai welcomes the UK governments recent Ten Point Plan, in particular the drive to decarbonisation through the use of hydrogen, said Rinnais Chris Goggin, who is also a board member of the ICOM Energy Association. The UK, along with many other countries, faces an energy trilemma the pressing need for decarbonisation, which means a shift in energy pathways; security and longevity of supply; and long-term affordability to the industrial and end consumer. The UKs housing stock is more than 24 million units and the country saw total energy consumption increase by 1.1% in 2018 to reach 143 million tonnes of oil equivalent (mtoe), the highest level since 2013. Government funding of 500m is available for trials for homes using hydrogen, starting with a hydrogen neighbourhood in 2023, moving to a hydrogen village by 2025, with an aim for a hydrogen town before the end of the decade. Of this funding, 240m will be for hydrogenproduction facilities. Rinnai has made data and information contributions, and had close consultations with the lead research agency primed with advising the UK government. All questions and queries on the growing consensus on the suitability of hydrogen as the replacement for all fossil fuels will be answered by the hub, said Goggin. Hydrogen can make a major contribution to decarbonising the UK energy grid, while also providing a sustainable answer to the political and societal questions of the energy trilemma. The distribution of hydrogen creates a resolution to the 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 costeffective hardware and software upgrades as demonstrated by proprietary technology in hot water heating units.

The system supplied comprises four N Series Sensei 1600i units on cascade frames with an additional 500L buffer vessel. The solution includes continuous-flow water heaters, BMS controls, remote monitoring facilities, Nexus electrolytic scale inhibitors, flexible flueing systems and more ancillaries, all underscored by continuing energy and carbon analysis of comparative product systems. Provided there are constant supplies of water and gas, Rinnai continuous-flow hot water systems will deliver a constant flow of temperature-controlled hot water throughout the building. The system also includes multiple valve kits and unvented cylinders to support compliance and enable best practice in system design. The innate technology offers high efficiencies and remote-monitoring capabilities by the seamless integration and monitoring with the onsite BMS. The new N Series arrangement incorporates connectivity controls to ensure each appliance is visual and addressable on the BMS system. We chose to install a cascade of Rinnais N Series water heaters to provide a robust and resilient system, able to cope with periods of high hot-water demand in this nine-storey building, Tel: 020 7880 6245 Email: cibsedirectory@redactive.co.uk CIBSE Jan21 pp49-52 Products.indd 49 said Theodore Jones, infrastructure manager for TfL. The N series units are compact and lightweight, affording ease of transportation to the ninth-floor plant room. The inherent modularity of this solution allowed for a rapid installation, and the finished system exhibits a smaller floor footprint than traditional HWS plant. The Rinnai Sensei N Series is the first 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. This installation contains many facets of our total product offering, all of which is aimed at maximum efficiency in both engineering and financial terms, said Rinnais Chris Goggin. On-demand limitless hot water with precise, controlled temperature is the cornerstone of our offering today to all sites of any size or use.
