INFINITY 1600 LOW–NOX
UNITS & SYSTEMS
MAKING ECONOMIC
SENSE FOR COMMERCIAL
& DOMESTIC SITES
Rinnai, the UK’s leading manufacturer of the
ErP A-rated Infinity range of continuous flow
condensing gas fired water heaters, delivers
the most energy efficient range of low-NOx hot
water heating units currently available to the UK
end user.
The company’s low-NOx Infinity HDC 1600e
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 extremely quiet in
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 when a building is closed.
By the time the building reopens, core temperature is 42°C for
safe use.
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, over time accumulate scale deposits
in hard water areas.
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 end user to contact 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.
The industry uptake on 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 1600e/i 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.
