PRODUCTS & SERVICES Products of the month Rinnai reveals 100% hydrogen for continuous flow water heaters Manufacturer one of the first to display I2HY20 gas category certification for all of its products R innai has created a continuous ow hot-water system fuelled by 100% hydrogen. In November last year, the company announced the release of its Rinnai Innovation Manifesto 2050, describing its commitment to global carbon neutrality. A Rinnai spokesperson said: As a company that produces appliances that require fossil fuels, Rinnai feels a deep sense of responsibility to embrace all aspects of global decarbonisation. Current UK Rinnai product ranges both domestic and commercial are hydrogenblends ready, which means that units will accept the proposed 20% hydrogen/natural gas blend. Rinnai UK is one of the rst manufacturers to display the I2HY20 gas category certicate for all its products. If we can develop a 100% hydrogen combustion technology that emits no CO2, we can help achieve carbon neutrality, the company spokesperson said, adding that Rinnais 100% hydrogen combustion water-heater models can contribute signicantly towards cutting emissions. He said: An adoption of global infrastructural modications is a prerequisite for hydrogen-burning water heaters to become a valid, global decarbonising technology. Major international economies are focusing on introducing clean and domestically sustainable sources of energy, such as renewables and hydrogen, into separate energy mixes before or around 2050. In the UK, HyNet North West is a project trialling hydrogen distribution and supply to both industry and residential sites The lead partner is Cadent, the UKs largest gas distribution network. Reports show that the trial is progressing up to and beyond expectations. In Australia, major energy companies are implementing a series of demonstration tests using 100% hydrogen water heaters in residential applications from October 2022. Rinnai will take part in these tests in the hope that its 100 years of experience can assist in producing technology that accepts clean energy. Chris Goggin, operations director at Rinnai UK, said: We are delighted to see this Chris Goggin, operations director at Rinnai UK development coming to market after a period of intense research and design work conducted on a global scale.

We have responded to the need for decarbonisation by redesigning those parts of our products that warranted it and we have recognised that all fuels will factor in the future. Hence, we have launched our H3 initiative hydrogen, hybrid and heat pump so that our customers have the best possible choices to assist them to maximise their own energy efciency programmes. Rinnai plans to continue researching and developing next-generation decarbonising technology. It is determined to introduce combustion technology that encourages a greater sense of customer convenience and clean air quality.
