Hot water is a daily essential in Australian homes. From that invigorating morning shower to the satisfying clean-up after a long day, it plays a vital role in our comfort and hygiene. But what if your hot water system isn't operating as it should? Specifically, what happens if your hot water temperature is set too high?

While it might seem like having scorching hot water readily available is a good thing, there are several downsides to consider. Here's why building inspections in Sydney should prioritise checking hot water safety and why you, the homeowner, should be aware of the consequences of excessively hot water.

The Scalding Risk: Hot Water Burns

The most concerning consequence of excessively hot water is the increased risk of scalding, especially for vulnerable individuals like children and the elderly.

Australia's Department of Health warns that hot tap water can cause severe scalding in just seconds at temperatures as low as 60°C [1]. This is because hot water penetrates deeper into the skin layers, causing more extensive damage compared to surface burns.

A building inspection in Sydney should verify that your hot water system is set to a safe temperature, typically around 50°C [2]. This helps to minimise the risk of scalding accidents in your home.

Safety Features and Upkeep

Building inspectors play a crucial role in ensuring your hot water system has the necessary safety features to prevent overheating and scalding. These features include:

• Thermostat: This controls the water temperature and automatically shuts off the heating element when the desired temperature is reached. A faulty thermostat can lead to the water exceeding safe limits.
• Temperature Limiting Valve (TLV): This mixes hot and cold water to maintain a safe outlet temperature, typically around 50°C. A malfunctioning TLV can deliver dangerously hot water at the tap.
• Pressure Relief Valve (PRV): This safety mechanism releases excess pressure that can build up due to overheating, preventing tank ruptures. A blocked PRV can be a major safety hazard.

A qualified building inspector will check these features during a pre-purchase inspection or routine maintenance inspection. They can also recommend servicing your hot water system by a licensed plumber to ensure optimal performance and safety.

Energy Efficiency and Cost Concerns

Beyond the safety aspects, excessively hot water can significantly impact your energy bills. Water heating typically accounts for a large portion of a household's energy consumption [3].

When your hot water system is set to a higher temperature than necessary, it constantly works harder to maintain that level. This translates to wasted energy and higher electricity or gas costs.

Building inspectors can advise on the most energy-efficient hot water system settings for your home. They can also identify potential inefficiencies in your system, such as leaks or ageing components, which can contribute to higher energy use.

Extending the Life of Your Hot Water System

Hot water systems are not designed to operate at excessively high temperatures. The constant strain can damage internal components, leading to premature failure and the need for costly repairs or replacements.

A building inspection in Sydney can identify potential problems caused by high water temperature, such as:

• Sediment build-up: High temperatures can accelerate the build-up of minerals in the water heater tank. This sediment can insulate the heating element, forcing it to work harder and reducing efficiency.
• Increased pressure: Overheating can lead to excessive pressure in the tank, putting stress on components and potentially leading to leaks or ruptures.
• Corrosion: Extremely hot water can damage the internal lining of the tank, leading to corrosion and leaks.

By keeping your hot water temperature at a safe and efficient level, you can extend the lifespan of your system and avoid unexpected repair costs.

Building Inspections in Sydney: Your Peace of Mind

When it comes to hot water safety and efficiency, a building inspection in Sydney offers valuable peace of mind. A qualified inspector can assess your hot water system, identify potential problems, and ensure it's operating safely and efficiently.

Here are some additional benefits of a building inspection in Sydney:

• Compliance with regulations: Building inspections can help ensure your hot water system adheres to relevant safety regulations.
• Increased property value: A positive building inspection report can enhance the value of your property when selling.
• Reduced risk of future problems: Identifying potential issues early on can save you money and hassle down the road.

Conclusion

Hot water is a household essential, but it's crucial to maintain a safe and efficient system. Building inspections in Sydney play a vital role in ensuring your hot water operates at the right temperature, minimising the risk of scalding, and optimising energy use. By taking a proactive approach to hot water safety, you can create a comfortable and cost-sharemore_vert
