1 Bosch continuous flow gas
hot water systems
1.1 Range overview
All Bosch hot water systems are continuous flow gas hot water systems,
which means they only heat the required water on demand. They are wallhung, easy to install and much smaller than conventional storage systems.

Australia. These units comply
with Australian Standards
3489-2003 (licence number
IPC20002). They have been
specifically designed for
applications, which require a
maximum water temperature
of 50°C. This eliminates the
need for mechanical tempering
valves.
**Only available in Australia.
***Only available in New Zealand.

unit, manifold (see chapter 2.3) or are delivered as part of
a Bosch Professional Pack, a pre-assembled system

xternal or internal* installation options make the 32
Series conveniently versatile.
u
U
p to 3 optional temperature controllers can be installed
with a Bosch 32 model (KM3211WHNG/LP only): 1 main
controller (RCM3211) and up to 2 sub-controllers
(RCS3211).
u
A
dditionally, the 32Q model (KM3211WHQNG/LP)
includes a built-in pump and a main controller, which
allows for programmed water re-circulation on a ring main
e.g. for peak usage times. The delivery time of hot water is
reduced as well as unnecessary water usage.
*Internal installations require flueing as per AS 5601 / NZ 5621.
Flue kits are available for 32 Series.
For more information, please see page 17.
14
The 32Q model allows for programmed water re-circulation
on a ring main. The maximum length of the re-circulation pipe
is 60m.
2.2 Professional Packs
Professional Packs are specifically designed for
commercial use. They are suitable for
applications that require a large volume of hot
water for peak demand. All Bosch Professional
Packs come with the following components –
Bosch hot water system, Bosch-Everlast
stainless steel storage tank, built-in
thermostat, shroud, PTR valve and pump. They
are pre-assembled, ready to be installed and
will be shipped directly to site. This means an
easy installation and low set-up costs.
The 315 litre Bosch-Everlast stainless steel
storage tank included in Bosch Professional
Packs comes standard with 32mm ports.
Bosch-Everlast stainless steel storage tanks
can also be purchased separately. A 315 litre
model with 32 mm ports (part number: 315C2)
as well as a 315 litre model with 50mm ports
(part number: 315C250) is available. The
315C250 storage tank is not available as part
of a Bosch Professional Pack.

make fault diagnosis as easy as possible. They also allow temperature
control accurate to the single degree.
