10 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 an 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.
