Water quality
All Bosch water heating appliances are constructed from high
quality materials and components, and all are certified for
compliance with relevant parts of Australian and New Zealand
gas, electrical and water standards.
While Bosch water heaters are warranted against
manufacturing defects, the warranty is conditional upon
correct installation and use, in accordance with detailed
instructions provided with the heater. In the case of the water
supplied to the heater, it is important that the water quality be
of acceptable standard.
The water quality limits/parameters listed in the water quality
table are considered acceptable, and generally Australian and
New Zealand suburban water supplies fall within these limits/
parameters.
In areas of Australia and New Zealand where water may be
supplied either fully or partly from bores, artesian wells, or
similar, one or more of the important limits may well be
exceeded and the heater could, therefore, be at risk of failure.
Where uncertainty exists concerning water quality, intending
appliance users should seek a water analysis from the water
supplying authority. In cases where it is established that the
water supply does not meet the quality requirements of the
water quality table, the Bosch warranty would not apply.
