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.
Whilst Bosch water heaters are warranted against 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 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 and 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.
