A heated water service used for consumption, food preparation, utensil washing or personal hygiene must be connected to a drinking water supply, and heated water from fixtures and appliances used primarily for personal hygiene must come out at a temperature unlikely to scald. Deemed-to-Satisfy maximum delivery temperature (B2D5): 45 degrees Celsius in the residential part of an aged care building, patient care areas of health-care buildings, children's areas of early childhood centres and schools, and designated accessible facilities in common areas, and 50 degrees in all other cases; B2D6 requires a thermostatic mixing valve or thermostatically controlled tap for the 45 degree cases and one of those, a tempering valve or a temperature limited water heater for the 50 degree cases, with the temperature achieved to AS/NZS 3500.4. It applies when a service is first installed, a water heater is replaced or relocated, several fixtures are replaced or the service is extended. B2D3 requires the heated tap to be on the left of, or above, the cold tap. Western Australia and other States vary B2D5 and B2D6.
