PRODUCTS & SERVICES Product of the month Rinnais success flows continuously with energy-efficient water heaters New products mean invasive building works can be avoided when replacing an old system A ccording to recent analysis, Rinnais continuous-flow hot water delivery units and systems can deliver a reduction in carbon emissions of at least 20% compared to conventional heated storage systems. This has positive implications for both the companys future and for the building performance sector as a whole, for which energy efficiency is becoming more of a priority. Rinnai specialises in continuous flow water heaters, which provide large quantities of usable hot water for comparatively small amounts of energy and offer a degree of precision that conventional heaters lack. These products come in two sizes, 47kW and 58kW, and are compatible with hydrogen blends and BioLPG. At 30kg in weight they are compact enough to require only a one-man lift, in contrast with older appliances which tend to be heavy, fragile and difficult to decommission. A typical water storage-based installation will cost 5,662.13 per year, whereas a Rinnai continuous flow water system will cost 2,736.02. When a stored water system comes to the end of its working life it is assumed that replacing like for like is the best option. Product development engineer Pete Seddon believes Rinnai can break this mould and make continuous flow water heating an industry norm. If we look at the like-for-like, out with the old one and in with the same model stored water heater, there is actually a major amount of work involved in this, he says. The hot water system has to be completely shut down to allow such major works to take place and not all sites can allow this to happen. Seddon explains that Rinnais products can bypass a large chunk of the invasive building works involved in installing a conventional water heating system. The other benefit is the ability to cascade these appliances so when more hot water is required you would simply add more continuous flow water heaters, he adds. This would mean that if one unit needs to be shut down the complete site still has ready access to hot water.

Rinnai we all win with net zero common sense, calm and commitment Firm pushes for a collective, equable effort from all sectors to ensure future sustainability T he topic of net zero and carbon emissions reduction in the hot water industry can be a contentious one, but water heater manufacturer Rinnai has responded to this with a stance of common sense, calm and commitment to its values. Rinnai believes that the best way to achieve the net zero goal is with a measured, pragmatic and transparent approach that involves all stakeholders in the heating and hot water industry: an approach that holds the manufacturing sector accountable for its contribution to harmful emissions while finding solutions that allow for the smallest possible amount of disruption to current standards of living. This will require manufacturers to shift their focus away from trying to create the best net zero product on the market and towards creating a culture of cross-communication and collaboration, fostering a sense of unity across all sectors. 54 March 2022 www.cibsejournal.com CIBSE March 22 pp54-56 Products.indd 54 Rinnai managing director Tony Gittings (pictured) says: Fact, logic and reason must be employed to achieve the best outcome for all of us. We need decarbonisation, we need net zero, and we need it as soon as possible but in such a way that is pragmatic in terms of catering to the existing populations and markets. We need to look at this from the consumers viewpoint, he continues. We need to be putting accurate information in the public arena. At the moment, there are a lot of interested bodies and companies showing understandable self-interest in wanting to know they have a future in the marketplace. A collective, equable effort will give us the result we all want, the result we must have, if we are to have a sustained quality of life. We are a business based on engineering excellence and are employing technological creativity to achieve the targets. In the UK, this will mean that we begin to offer a wider range of products under the H3 umbrella of hydrogen, heat pumps and hybrid systems to enable our customers to achieve their own carbon reductions and eventual neutrality.
