PRODUCTS | SERVICES Products of the month Rinnai units supply limitless hot water on demand to offgrid sites gas emissions by up to 85%. Before this development, LPG was the lowest-carbonemitting source of fuel for the 15% of UK businesses and homes that function off grid. BioLPG releases no harmful emissions, and DME performs to a higher standard when compared with heating oil. LPG and BioLPG are the ideal solutions for rural or off-grid commercial business use. An adaptation to BioLPG is simple and swift, and new BioLPG units can be dropped in. The transition to BioLPG will ensure businesses can continue to operate normally and efficiently, with limited disruption and minimum stress no technical adjustments are required to your heating and hot-water system. BioLPG and LPG are interchangeable, which means the fuel can be used with a current Rinnai system. The performance of BioLPG is comparable with LPG, as is DME when compared with diesel. They can create cleaner local air and help meet international decarbonisation targets. Alternative fuel sources to LPG and diesel oil can be used in Rinnai systems, says the companys Chris Goggin L ow carbon alternatives to liquid petroleum gas (LPG) and heating oil can be used in Rinnai hot-water heating units and systems. Further alternative fuel sources are currently in demand because of the impact of the war in Ukraine. BioLPG is a lower-carbon-intensive source of fuel than LPG, and is made from a blend of waste, residues and sustainably sourced material. Renewable biofuel dimethyl ether (rDME) is a molecule-based fuel produced through renewable feedstocks, and can be used to replace heating oil. It has a very high cetane number, which is a measure of the fuels ignitibility in compression ignition engines. The energy efficiency and power ratings of rDME and heating oil engines are virtually the same, but rDME can reduce greenhouse Rinnais continuous flow hot water heating systems for all commercial applications The Rinnai N Series of hot water heaters installed, on site Visit www.rinnaiuk.com Rinnai CPD reveals carbon and expenditure savings in hot-water heaters New service allows manufacturer to analyse users carbon emissions and advise on potential savings A new Rinnai CPD shows the carbon and cost savings that can be achieved through investing in both hydrogen blend-ready and BioLPG-ready continuous flow hot water heaters. The CPD Carbon and economic benefits of zero storage in hot water systems is available on Rinnais website www.rinnauk.com. The current rise in energy prices and living costs is an issue at the forefront of many peoples minds at the moment. Rinnai is continuously working to produce products that will benefit the customer in terms of performance, finance and convenience. The companys research shows that instantaneous hot-water systems offer significant savings over traditional storage systems in five key areas: operational costs; capital cost; carbon footprint; space; and weight. The approximate savings that can be achieved by replacing a traditional 54 July 2022 www.cibsejournal.com CIBSE July 22 pp53-56 Products.indd 54 storage-based system with a commercial Rinnai continuous flow hot-water system amount to: 15-20% on running costs; 30% on upfront costs; a 15-20% reduction in carbon; a 60% saving in space; and an 80% saving in weight. A three-step formula has been created to measure these cost and carbon savings calculations. The first step collects and processes data from previous real-life projects. This data is used to gain a better understanding of peak-loading conditions and usage patterns. The second step then sizes the system according to the loading. Finally, the third step calculates the capital expenditure, operational expenditure, carbon emissions, efficiency, energy use, performance, plant space, and weight. Rinnai is a registered provider of CPD courses with CPD UK and CIBSE. Each course is designed to facilitate a better technical understanding of low carbon heating, and hotwater delivery systems. Rinnais CPD courses can be found on its website by keying training into the Rinnai search area, located at the topleft side of the opening webpage. The CPDs are free to all. Rinnais recent CPDs aim to increase knowledge, skill and expertise, and offer an insight into the current energy market, and how continuous flow technologies actively assist in customer cost and carbon reductions.
