Product overview

HydroPower Ignition is exclusive to Bosch - it does not require
a 240V power supply.
HydroPower uses the energy created by the water flow to
ignite the burner and begin the heating process. The unit
only starts when a hot water tap is opened. Once the tap is
turned off, the unit turns off.

Description of the Hot Water Unit

Hot Water Unit for external wall-mounting only
Available in Natural gas or LP gas
Hydrogenerator produces sufficient energy to ignite and
control the heater
– Water enters the Hydrogenerator
– The turbine spins with water flow
– A voltage is generated by the turbine
– This voltage causes the ignition control unit to light a
temporary pilot
– The water pressure opens the main burner gas valve
and the pilot ignites the main burner, the pilot then
goes out
– The water flows through the heat exchanger where it is
heated
Safety devices:

– Flame rod to check for accidental extinction of the
burner flame
– Overtemperature switch to prevent overheating.
Water filter on the inlet water supply
Economical
Only heating water when required, the Bosch range is
extremely economical to run.
Versatile
LPG models are particularly popular in country areas, where
Natural Gas is not available.
Low Temperature Areas
In areas where the atmospheric temperature may drop to 0 °C
for brief periods, the installation of an EXOGEL valve (part
number H707 060 151) will minimise the possibility of
damage to the appliance if the water freezes.
NOTICE:
This water heater MUST NOT be installed in
areas where the temperature remains below
0 °C for extended periods.
