• Gas-Fired Water Delivered Efficiently

Rinnai’s ErP A-rated Infinity 1600 range of continuous flow condensing gas fired units are designed to deliver both energy efficiency and cost competitive hot water heating.

Rinnai manufactures over 2 million hot water heating units each year and so can offer cost savings for installers and end users.

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 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. 

Scale

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.

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 show that continuous flow heater systems are proven to be energy efficient and are often the experts’ preferred method of hot water provision.

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.

Picture: SMART control.
