Residential Hot Water System Standards and Scalding Prevention Regulations

Summary

Australian plumbing standards dictate specific temperature parameters for residential hot water systems. Storage hot water units must store water at minimum temperatures of 60°C to prevent bacterial growth such as Legionella. However, delivery temperatures at personal hygiene taps, including bathrooms, should be tempered to a maximum of 50°C using tempering valves to prevent scalding. Landlords must ensure qualified plumbers maintain these systems in accordance with local regulations to protect occupant safety and remain compliant.

Key Points
