Rinnai Hot Water
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
