Ultimately, ongoing use with hard water may shorten the lifespan of conventional water heating appliances and systems. To safeguard against this Rinnai units continually self-monitor for lime scale deposits around the heat exchanger. If a lime scale build-up is identified, a message is sent to the built-in interface panel on the front of the appliance. The message is displayed as ‘LC’, which alerts the homeowner to contact a Rinnai service agent to perform a lime scale flush to clear the potentially harmful deposits. The industry uptake of Rinnai’s series of low-NOx high efficiency products is that continuous flow heater systems are proven to be more energy efficient than conventional storage systems and are increasingly the experts’ preferred method of hot water provision. Rinnai units easily cater for any size projects that need high volumes of water at intermittent times of day. The Rinnai Infinity 1600i offers condensing technology with up to 107% gross efficiency, ultra-low- NOx of less than 20 ppm, a widely expansive modulation range of 54kW-4kW and high flow rates of 37/ltr/min. Add to these benefits, the peace of mind of an extended warranty, a top A-rating exceeding the demands of eco-labelling legislation, and the knowledge that the HDC1600 is future-proofed against future regulatory and legislative changes.
