PRODUCTS & SERVICES Products of the month Rinnais Sensei N Series range: providing limitless hot water with precise control The UKs first continuous-flow water heating unit that is also good for the environment R innais Sensei N Series features a range of models designed to ensure reliable hot water delivery for every possible site requiring limitless hot water with precise temperature control. The Sensei N Series is the first continuousflow water heating unit in the UK that is manufactured with stainless steel heat exchangers, which greatly extend the working life of all four models in the range. N Series heaters offer a more compact and enhanced combustion design that allows for easy installation, superior operational performance and high serviceability. All four models have a class A water efficiency rating and a dispersion rate of at least 775 litres per hour at 50oC. Other features include turbo fans; built-in controllers on both internal and external models; an air inlet filter; frost protection for temperatures below 20oC; a built-in flue damper; and a maintenance monitor for engineers. The cascade cable assembly allows up to 24 water heaters to be connected and function as one total and complete system. Any number of N Series water heaters can be manifolded together, allowing for some of the largest capacity on the market. All Rinnai N Series range models are lowNOx and use Rinnais patented advanced burner technology, with a 13-1 turn-down ratio that offers extremely quiet operation. Integral controls on the units enable the water heater to achieve high efficiencies due to advanced burner control and high modulation ranges. The advanced burner controls with the Sensei N Series models ensure that all appliances are well ahead of the NOx requirements set within ErP. The current level of permissible NOx set by ErP is 56mg/Kwh. The Sensei N Series range has been third-party tested at 28mg/Kwh, making them one of the greenest water heating appliances available. Rinnais continuous-flow heater systems are proven to be more energy-efficient than conventional storage systems and are becoming the experts preferred method of hot-water provision. Rinnai units easily cater for any size projects that need high volumes of water at any time of day.

We aim to continue working towards net zero without compromising product quality or customer satisfaction. Rinnai has also commissioned a comprehensive comparative report focusing on gas and electrical appliances utilising a variety of energy vectors in both residential and commercial scenarios. The report is headed by a prominent multi-national consultancy firm within the building sector: a team of empirically motivated, non-partisan academics who will supervise the final draft of Rinnais energy efficiency review. An appliance analysis will concentrate on the separate levels of energy efficiency of individual products. The consumer needs to be given the facts to make an informed decision, says Goggin. We have positioned ourselves as a company that offers the highest quality products and excellent service. We have a responsibility to do the absolute best we can for our customers, and that includes anticipating the future. Visit www.rinnaiuk.com www.cibsejournal.com April 2022 65 25/03/2022 14:33
