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:

3 Up to 16 litres per minute with 50ºC 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 flexibility.

Large Domestic

A commercial condensing water heater is ideal for larger applications where:

3 There is increased demand for domestic hot water

(DHW) – e.g. Multiple fixtures such as sinks and showers

3 Pre-heated water supply is to be used – e.g. by solar thermal

Typical examples include larger homes and small hotels.

Light commercial/non-domestic

Ideal for light commercial or non-domestic applications with:

3 High demands for DHW – e.g. multiple fixtures such as sinks and showers

3 Where demands for DHW are consistent throughout the day

Commercial

Suitable for large commercial applications where there is:

3 Consistent high demands for DHW – e.g. laundries, hospitals

3 Very high cyclic demands for DHW – e.g. hotels, schools

Bosch 32C’s ability to use water pre-heated by renewable heat sources supports planning and investment requirements.

Such applications can take full advantage of the cascade controls that are part of the Bosch 32C offering. These controls provide the ability to deliver up to 192 litres per minute of hot water on demand at a 25°C rise.

Certain commercial applications may also take advantage of the ability to provide a hot water temperature of up to

85°C for sterilisation processes and secondary circulation.

Cascading

Linking up to 6 water heaters together in parallel allows a maximum water flow of up to 192 litres per minute with a 25ºC rise.

Bosch’s intelligent cascading software will automatically rotate the lead appliance after each 8 hours of operation, distributing the workload equally across the water heaters in the cascade, increasing the longevity of the appliances.

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.

A safety valve is mandatory and expansion vessel recommended for recirculating systems.

Use with renewables

A Bosch 32C water heater is designed to work with preheated water, for example, from a solar thermal system or heat pump(s).

Fluing

Fluing for internal installations of the Bosch 32C, is a system which is supplied exclusively by Bosch.

These high quality flue components are made from polypropylene (PP), making them corrosion resistant, and easy to install.

The 32C flueing includes easy push-fit joints, lightweight components and vertical and horizontal flue terminals.

Bosch 32 & Bosch 32Q

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.

Vertical Flue Kit

The vertical flue kit contains the following components

3 100mm gas cowl

3 1.5m x 100mm diameter gas flex (3 piece)

3 Flue pipe adaptor (3 pieces)

3 Support struts (2 pieces)

3 3m x 6mm condensation hose

Horizontal Flue Kit

The horizontal flue kit contains the following components

3 100mm diameter flexible flue, 5m long

3 Flue sleeve

3 Adjustable wall penetration sleeve (2 pieces)

3 Clamp

The following considerations should be made when planning the installation

3 Vertical sections of flue must be as short as possible

3 Ensure the joins are gas tight and will not leak. Use heat resistant silicon sealant wherever necessary.

3 Use a maximum of 1m straight pipe before the first elbow

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.
