Rinnai hot water – instant, continuous, limitless and sensibly economic for all large commercial sites - the Infinity 1600 offers lowest Low-NoX guaranteed
Rinnai, the UK’s leading manufacturer of the ErP A-rated Infinity range of continuous flow condensing gas fired water heaters, supplies the best energy efficient range of low-NoX water heating units currently on the market.
Advanced condensing heat exchangers combined with innovative down firing pre-mix burner technology ensures that every cubic metre of natural gas or LPG is used to the maximum in the Infinity HDC 1600. The renewables-ready units are suitable for use as a temperature booster for solar thermal and heat-pump installations. The HDC1600 is also future-proofed against future regulatory and legislative changes.
The Rinnai low-Nox Infinity HDC 1600 external wall mounted unit (together with the interior HDC 1600i version) utilises Rinnai’s patented pre-mix burner technology with a 14-1 turn down ratio – the largest on the market – of 58.4kw-4.05kw and is ultra quiet in operation.
Integral controls on the units also enable the water heater to achieve high efficiencies whether locally or when integrated into a building management system. Legionella proliferation is reduced significantly by Rinnai: the company 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 at a time when the building is closed. By the time the building reopens, core temperature is 42°C for safe use.
“The industry uptake on the whole series of Rinnai’s low-NoX, high efficiency products, across all sectors, has been nothing short of phenomenal,” says Rinnai UK Associate Director Chris Goggin. “We are supplying products and systems that give our customers compliance and perform at economic costs far superior to the conventional mode of stored water systems.”
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.
The system helps to ensure the performance and efficiency of Rinnai‘s 1600, and all of its continuous flow water heaters installed in hard water areas. Almost all water-fed appliances, including plate heat exchangers, boilers and water heaters will accumulate scale deposits when used within hard water areas over time.
Lime scale consists chiefly of calcium carbonate (calcite), and lime scale deposits can build up affecting the performance of water heaters by reducing their efficiency and overall performance.
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 has being 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 end user that it is time to call a Rinnai service agent to perform a lime scale flush to clear the potentially harmful deposits. This avoids and eliminates the adverse effects associated with lime scale build up, including lower energy efficiencies and potential product de-generation.
Rinnai Infinity HDC range 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 are the peace of mind of an extended warranty, a top A-rating exceeding the demands of eco-labelling legislation, the flexibility of external wall mounting and delivery to site with all relevant accessories and the knowledge that the HDC1600 is future-proofed against future regulatory and legislative changes.
