The Bosch 32C Commercial
continuous flow water heater
Global responsibility for nature and the environment
Bosch Thermotechnology is committed to environmental
protection. Product development is being prioritised in
the interests of peoples well being, the economical use
of resources and environmental sustainability.
In just a few short years, Australia’s domestic heating
and hot water industry has changed dramatically.
Words and expressions such as “renewable energy”,
“sustainable technology” and “carbon footprint” have
become a part of everyday conversation and have been
fuelled by extreme weather and stark television images.
Bosch Thermotechnology, while not continuing to satisfy
the daily demands for heating and hot water comfort, has
taken a lead in developing solutions which reduce the
impact on the environment by reducing CO2 emissions –
not only for today but well into the future.
With this in mind Bosch is proud to offer a high
efficiency, high output gas-fired condensing continuous
flow water heater for use with renewable energy sources
or traditional fuels.
With an output of up to 57.5kW, Bosch 32 Series water
heaters are ideal for use in high end residential, and
both small and large commercial applications. It offers
high energy-efficient condensing operation and up to
6 appliances can be cascaded in parallel offering a
combined flow rate of up to 192 L/min.

The features of the 32C
commercial water heater
Energy saving condensing design
The use of a condensing appliance contributes to
achieving higher efficiency by incorporating a secondary
heat exchanger. Heat within the flue gases is used to
preheat the inlet water, and so recaptures energy that
would otherwise be lost.
Applications
The Bosch 32C water heater has been optimised for use
in domestic and commercial applications where there are
high demands for domestic hot water (DHW).
At 57.5kW heating output, the Bosch 32C water heater
offers the following performance:
3Up to 16 litres per minute with 50ºC rise
3Up to 32 litres per minute with 25ºC rise
The Bosch 32C water heater can be used with Natural
Gas (NG) or Liquid Petroleum Gas (LPG) and can be
installed in single appliances or multiples of up to 6
appliances. Extended flue lengths of up to 13m are
also possible, helping to provide even greater design

Key benefits for installers
Secondary circulation
The Bosch 32C has a durable heat exchanger that allows
it to withstand the frequent low-fire rates of a secondary
circulation system.
To reduce water wastage, a secondary circulation system
will circulate hot water through the pipe work of the
property to ensure hot water is immediately available
when a tap is opened.
The pump and control system will need to be purchased
separately, however no additional accessory is required.

This system is supplied with a pre-installed condensate
neutralisation system. This neutraliser will remove any
acidity that is present in the condensate. This means that
no further steps are required to treat the condensate,

opening, gas utility meter, service regulator etc
3Terminate the vent system at least 600mm above but
not more than 2m above the roof line
3Provide vertical support every 3.6m of flue
3Slope the horizontal vent 50mm upwards for every 1m

Flueing configurations
The Bosch 32 and 32Q water heaters are flued by the
flue kits available. The vertical and horizontal flue kits
contain components required for most applications.
The maximum acceptable flue length is 13m. For every
90 degree elbow 2m should be subtracted from this
length. All internal gas water heaters must be flued and
installed with adequate ventilation in accordance with
AS/NZS5601.

System Layouts
Flow and return applications
The Bosch 32 has a durable heat exchanger that allows
it to withstand the frequent low-fire rates of a flow and
return system.
To reduce water wastage, a flow and return system will
circulate hot water through the pipe work of the property
to ensure hot water is immediately available when a tap is
opened.
A thermostat placed in the pipe work at a distant point
to the heater activates a pump when water temperature
drops below a set point, thus activating the appliance.
Bosch supplies Wilo dual secondary pump systems
and thermostats to be installed in flow and return
applications. For the performance of these pumps please
refer page 36.
The pump will need to be purchased separately, however
no additional accessory is necessary. A safety valve
is mandatory and expansion vessel recommended for
recirculating systems.
Use with renewables
A Bosch 32 series water heaters are designed to work
with pre-heated water from, for example a solar thermal
system or heat pump system.
