HydroPower Ignition is exclusive to Bosch. HydroPower uses the energy created by water flow to ignite the burner and begin the heating process.
The unit only starts when a hot water tap is opened. Once hot water is no longer needed, the unit turns itself off.
External HydroPower models are perfect for a constant, reliable supply of hot water. The HydroPower ignition provides endless hot water at the flick of a tap, without the need of power point.
- LPG models are particularly popular in country areas, where reticulated gas is not available and there is no external power point.
- They are able to operate in relatively low water pressure areas and in low temperature regions of Australia and New Zealand using Bosch accessories. Economical
- Only heating water when required by the user, the Bosch range is extremely economical to run.
Limited space need not mean limited hot
water. The Bosch range of internal hot water
heaters are created specifically to go places
where storage units will not, and will provide
endless hot water.

Water Flow Adjustment
Turn anti-clockwise Water flow increases, temperature diminishes
Turn clockwise Water flow decreases, temperature increases.
If the appliance does not operate, burns with yellow flame, leaks water or a gas smellis evident, turn off and contact the local gas authority, the manufacturer or anauthorised service person.
In areas where the atmospheric temperature may drop below 0°C the heater may be
drained to prevent damage by expansion of freezing water. For appliances installed in locations where the temperature falls below 0°C and not less than -2°C for brief periods, the installation of an EXOGEL expansion valve, part number H707 060 151, will minimise the possibility of damage to the appliance.
This water heater MUST NOT be installed in areas where the temperature remains
below 0°C for extended periods.
CAUTION: It is recommended that for sanitary fixtures used
primarily for the purpose of personal hygiene that a temperature
control device be fitted (such as a tempering valve) as per

We recommend that the appliance be inspected and cleaned by an authorised
person periodically, depending on the frequency and duration of its operation, but
never less than once in a two year period.
