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.
