PRODUCTS & SERVICES Products of the month Hot-water audits tackle cost-of-living squeeze Rinnai is offering a free audit of hot-water system energy costs on all sites, which may lead to customer fuel savings of up to 30% F ree audits of total energy costs related to hot-water systems on all sites are being offered by Rinnai. Specifically aimed at maximising hot-water delivery efficiencies, the audits will contribute to significant savings on fuel costs to the end-users. Maximising efficiencies on site could result in fuel cost savings of up to 30% on current energy prices. Rinnai says its continuous flow technology means that hot water is heated only when required. It says benefits are seen because energy costs stop immediately once the tap is not in manual use. The total capital expenditure and carbon savings are to be included in the audit for the final whole life calculation. The audit measures all data from both individual and multiple sites concerning hot-water use, and presents a full and detailed report. This is our response to the tightening squeeze on costs that all businesses, commercial sites and homes are currently facing. We have a range of products, which includes gas-fired solutions, hydrogen-20% blends ready, BioLPG and solar to electric heat pumps, as part of our H3 initiative of hydrogen, hybrid and heat pumps, says Tony Gittings, managing director at Rinnai UK. Recently, the company announced a global first, with the development of 100% hydrogen hot-water heating technology. Current UK Rinnai product ranges both domestic and commercial are hydrogen blends ready. This means that units will accept the proposed 20% hydrogen/natural gas blend. Rinnai UK is one of the first manufacturers to be able to display the I2HY20 gas category certificate for all its products. The company has also announced that it will help in reducing the carbon footprints of all sites and applications with the introduction of its Carbon Cost Comparison Form. This can be completed online; however, hard copies of the form are available on request. The form offers a free appraisal of a sites current hot-water delivery system, along with recommendations for how customers can go about reducing the carbon load. To access the advice, the user simply visits 94 September 2022 www.cibsejournal.com CIBSE Sept 22 pp94-96 Products.indd 94 the Rinnai website, completes the form and hits the Submit prompt. Following this, Rinnai will complete a thorough analysis, which is then returned. The Rinnai Carbon Cost Comparison Form is part of the Rinnai suite of innovative digital touchpoints. Easy to use, the pages are designed to make customer decision-making fluid and specific. Continuous flow hot water heating units and systems deliver proven reductions on working costs and quantifiable improvements in energy efficiency, as well as providing temperature-controlled end-product whenever the need arises, says Gittings. The user pays only for fuel used to heat the water at point of use not when on standby, as in stored tank holding systems, creating cost-effective and carbon-reducing solutions for systems on the gas grid. Our carbon calculation service, however, will compare our complete H3 array of hydrogen blend ready water heaters, hybrid solar and heat pump systems, and stand-alone heat pump solutions, providing our customers with market-leading, low carbon solutions. All of Rinnais units are UKCA certified, with A-rated water efficiency, and can be accessed through multiple fuel options.
