Heating, Ventilation & Insulation
end residential houses
- as installers and end
users become aware of
the ease of installation,
and the energy & cost
saving benefits.
Rinnai manufactures
over 2million water
heaters every year
and as such is at the
forefront of creating
unit cost advantages for
installers. Competitively
priced, the units offer all
technological advances
and innovations, all at
a similar cost to lower
specification competitor
models.
The reason for the
increase in popularity
is that continuous
flow heating systems
are proven to be more
energy efficient than
conventional ones and
are now the preferred
method of hot water provision. Rinnai
units meet the demands of any size of
home and are ideal where high volumes
are demanded at intermittent times of
the day, delivering safe temperature
useable hot water.
Rinnai’s multipoint 17i water heater,
for example, eliminates the problem of
sudden changes in water temperature,
resulting in cold showers or scalding
hot baths – the water temperature you
set is the water temperature you get.
So, if somebody is happily showering
at 42°C and a tap is turned on to draw
a bath elsewhere in the property, the
temperature does not vary, and there is
no chance of either user running out of
hot water.
Rinnai’s range of ErP A-rated
continuous flow gas-fired hot
water heaters now includes models
specifically aimed and designed for
the UK domestic market. The units
guarantee high efficiencies and low
running costs combined with consistent
water temperatures seven days a week.
Rinnai’s range of continuous flow water
heating units are being specified and
installed in the whole range of domestic
properties – studios, flats, houses, high-
The Rinnai 16i interior model measures
just 675 x 370 x 139mm and weighs in at
18kg - a one-man lift. The room-sealed
unit has a temperature range of 35°C to
60°C with direct electronic ignition. Gas
consumption ranges between 4.7kW-
6.5kW for Natural Gas and 4.9kW-
36.8kW when using propane. Hot water
delivery flow is an impressive 16ltr
max flow. Nominal operation pressure
is 1-7 bar and it uses a 230V AC 50Hz
1ph power supply with an electrical
consumption of 68W.

Meanwhile, where an external
installation is required, the Rinnai 17e
external multipoint water heater offers
greater flexibility at the design stage
and offers a viable solution where flue
runs are problematic or internal space
is not available. Capable of flow rates
of up to 510 litres per hour at a 50°C
rise, the 17e is suitable for multiple
applications and can be specified for use
with Natural Gas or propane.
The 17e has full frost protection and
is available with a range of external
ancillary items, including pipe
cover box – and security cage where
necessary.
For smaller properties, the Infinity 11i
interior unit differs from the 17i as it
weighs 2kg less at 16kg and consumes
6.10kW-21.60kW of Natural Gas and has
an 11-litre maximum flow.
Key features of the 24kW Rinnai 11i
are: Compact & lightweight unit
for easy installation; Robut, durable
heat exchanger; User friendly digital
controls; In-built frost protection; Ideal
replacement for large obtrusive and
bulky cylinder; Compact design to fit a
limited space.
