Rinnai 1600i Gas-Fired Water Heaters Delivering Energy And Cost Efficiency Now available is Rinnai’s ErP A-rated Infinity 1600 range of continuous flow condensing gas fired water heaters, designed to deliver the most energy efficient and cost competitive hot water heating units to any UK site or application. Rinnai manufactures over 2 million hot water heating units each year and so can offer advantageous cost savings for installers and end users. The units are probably the most competitively priced type of their kind currently available to the UK sector. The company’s low-NOx Infinity HDC 1600i models utilise Rinnai’s patented pre-mix burner technology with a 14-1 turn down ratio – the largest on the market – of 58.4kw-4.05kw with extremely quiet operation. Integral controls on the units enable the water heater to achieve high efficiencies whether locally or integrated into a building management system. In reducing Legionella proliferation, Rinnai has developed additional ‘SMART’ controls for secondary return DHW systems in 70 the form of an advanced temperature control system which allows for safe running of water at 42°C core temperature during the day and 60°C overnight. Another Rinnai innovation addresses an age-old industry problem with hot water delivery - lime scale build-up. The company’s integrated scale control system is an innovative solution and comes in the form of an LC (lime check) code on the display of the controller.
