Hot water systems in Australia must meet certain regulations for installation, temperature and safety. The regulations state that delivery temperature to bathrooms must not exceed 50°C to prevent scalding. Our licensed plumbers can install or repair your system to meet all required regulations.
Hot water systems are a crucial home feature in Australia, providing essential heated water for daily activities such as bathing and cleaning. To address hot water safety issues and support sustainable energy use, Australia has regulations around hot water heater installation, temperature control, and efficiency.
Yet, the risk of scalding from hot water is a significant concern, especially for children, the elderly, and those with sensitive skin.
Excessively hot tap water is a significant safety hazard, with vulnerable groups such as children and the elderly being at greater risk. Young children have thinner, more delicate skin, requiring careful temperature control, and seniors often have impeded mobility, which can prevent speedy avoidance of hot water.
Australian regulations set a maximum water temperature of 50 degrees Celsius at showerheads and taps, ensuring a safe guard against scalding. Aged care facilities and other institutions caring for at-risk individuals have an even lower maximum of 45°C. Exceeding these temperatures results in severe scalding, potentially causing third-degree burns in just 1 second at 68°C.
Implementing measures to regulate water temperature is essential. Thermostatic mixing valves automatically blend hot water with cold water to ensure delivery temperatures remain below hazardous levels, while tempering valves preset a maximum temperature the system cannot exceed.
Adhering to new hot water system regulations is akin to taking common-sense safety measures, such as keeping the bathroom door closed to avoid hazards. Advising on and installing temperature control devices with every new system is crucial for enhanced safety.
Aligning your hot water systems with national health, safety, and sustainability standards is critical, and requires compliance with the Australian code, AS/NZS 3500.
A key stipulation for storage systems, particularly those with a hot water tank, is heating water to at least 60°C to prevent Legionella bacteria growth. However, delivery temperatures at outlets must be capped to ensure water is both ample and safe for use, adhering to scalding prevention guidelines through the use of thermostatic mixing valve systems.
Tempering valve devices, thermostatic mixing valves and other temperature limiting instruments are mandatory to align storage and delivery temperatures with regulations.
Beyond national standards, additional building codes at the state level related to water tank installations may also apply. For instance, in South Australia, new hot water systems must include rainwater tanks connected to toilet flush systems. Ensuring compliance with system installation regulations and checking local requirements is vital for your new system to meet all necessary standards.
Australian plumbing regulations mandate installation of temperature control devices on all new and replacement hot water systems from 2022 onwards.
Tempering and thermostatic mixing valves, both requiring installation by a licensed plumber, automatically blend hot water with cold, ensuring a safe delivery temperature of 50°C to prevent scalding. However, these devices operate differently:
When installing either device, which can turn hot water to safer temperatures, certified plumbers must:

We ascertain that every installed system meets the mandatory energy rating of 3.5-6 stars, as stipulated by small-scale technology certificates (STCs), and includes tempering valves to safeguard against scalding.
Regular maintenance is vital for hot water storage tank components to remain compliant, efficient, and safe throughout their lifespan. As parts wear or sediment build-up occurs, performance drops while running costs and risks increase.
We recommend homeowners schedule annual hot water system maintenance checks covering tasks like:
Assessing factors impacting energy efficiency, such as insulation and system size, is imperative to accommodate varying hot water demands.
Expert standard and preventative maintenance safeguard your hot water system’s reliability, safety, and performance. Contact us to schedule annual servicing giving you peace of mind your system meets requirements.
Hot water regulations aim to ensure safety, efficiency, and reliability. Here we answer common questions on meeting Australian standards:
While hot water storage tanks must maintain water at least 60°C to prevent bacteria growth, taps should restrict water to safe levels. However, the delivery temperatures at the hot tap and showers must not exceed 50°C to prevent scalding.
Yes, minimum legal efficiency ratings are either 3.5 stars for electrical (solar/heat pump) or 5-6 stars for gas systems.
Tempering valves and thermostatic mixing valves automatically blend hot tank water with cold to keep the water hot yet at safe delivery temperatures.
A qualified plumber can size, install, and maintain temperature control devices, ensuring adherence to Australian Standards.
Fines of thousands of dollars may apply for unlicensed or non-compliant work related to all hot water installations under legislation like the Plumbing and Drainage Act.
