Rinnai’s Infinity HDC 1600e range optimises fuel use with advanced condensing heat exchangers combined with innovative down firing pre-mix burner technology. Whether the system is natural gas or LPG, every cubic meter of fuel is used efficiently, and Rinnai offers the reassurance of low-NoX functionality.

The units are also renewables-ready and suitable for use as a temperature booster for solar thermal and heat-pump installations. The HDC 1600e is also future-proofed against regulatory and legislative changes. 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.

The low-Nox Infinity HDC 1600e external wall mounted boiler (and the interior HDC 1600i version) utilises Rinnai’s patented pre-mix burner technology and is ultra quiet in operation.

Integral controls on the units support energy efficiency whether locally or when integrated into a building management system. Legionella proliferation is also significantly reduced too. Rinnai has added 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 when the building is unoccupied. By the time the building reopens, core temperature is 42°C for safe use.

The added benefits of the Rinnai products include 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.

“The uptake on the whole series of Rinnai’s low-NoX, high efficiency product, across all sectors, has been nothing short of phenomenal,” says Rinnai UK associate director Chris Goggin.
