Optimal Hot Water Setting

The Ultimate Guide to Hot Water Heater Settings: Staying Safe and Saving Money

The recommended temperature for hot water stored within a storage water heater such as Gas or Electric Storage Tank, Solar Storage Tank, or Heat Pump system should be between 60-65 degrees Celsius. 

Having the optimal hot water temperature provides several benefits, including:

1. Improved Safety

By maintaining the recommended temperature for hot water, the risk of scalding and burns is significantly reduced, especially for children and the elderly.

2. Enhanced Efficiency

The optimal hot water temperature allows for more efficient water heating, reducing energy consumption and lowering utility bills.

3. Better Hygiene

 Water stored at higher temperatures, as recommended for storage water heaters, helps prevent the growth of harmful bacteria, such as Legionella, which can cause serious illnesses.

4. Increased Comfort

With the correct temperature, hot water is more enjoyable to use, providing a comfortable and relaxing shower or bath experience.

5. Longer lifespan of the Water Heater

Operating a water heater at a temperature too high can cause it to deteriorate faster, which can lead to costly repairs or replacement. By maintaining the optimal temperature, the lifespan of the water heater can be prolonged, saving money in the long run.

The Dangers of High Hot Water Temperatures

It is essential to understand the dangers of having high hot water temperatures in your home. While hot water is necessary for daily tasks like showering and cleaning, water that is too hot can pose serious health risks. The most significant danger of high hot water temperatures is the growth of Legionella bacteria, which can cause Legionnaires’ disease, a potentially fatal form of pneumonia, especially for those with weakened immune systems.

In addition to this, hot water provided to sanitary fixtures such as wash basins, showers, and baths should not exceed 50 degrees Celsius to prevent scalding and burn injuries. This is particularly important for children and the elderly, who are more susceptible to burns. Even a few seconds of exposure to hot water at high temperatures can cause severe injuries.

It is important to note that hot water can be provided to the kitchen sink or laundry at a higher temperature of 60 degrees Celsius, as water at these outlets is less likely to cause harm or injury, and hotter water is often required for cleaning tasks. It is crucial to ensure that your hot water system is correctly set up and maintained to prevent any dangerous situations from occurring. By maintaining the optimal hot water temperature, you can ensure the safety and well-being of your family and save on energy bills, making it a win-win situation.

How to Adjust Hot Water Heater Temperature

Adjusting the hot water heater temperature is a simple process that can be done by following a few easy steps. However, it is important to note that before adjusting the temperature, it is crucial to determine the recommended temperature for your hot water heater. In Perth, Western Australia, the recommended temperature for hot water stored within a storage water heater, such as a gas or electric storage tank, a solar storage tank, or a heat pump system, is between 60-65 degrees Celsius.

To adjust the hot water heater temperature, locate the thermostat on your hot water heater. The thermostat is usually a dial or a button, and it may be located on the side or front of the tank. Turn the dial or push the button to adjust the temperature to the desired setting. It is recommended to adjust the temperature in small increments, waiting for a few hours in between each adjustment to allow the water temperature to stabilise.

It is important to ensure that the hot water heater is set to the recommended temperature to prevent any potential dangers, such as scalding and burn injuries, as well as the growth of Legionella bacteria. It is also essential to hire a professional plumber to adjust the hot water heater temperature to ensure the optimal setting is achieved. A licensed plumber has the necessary knowledge and experience to safely adjust the temperature and can also identify and address any underlying issues with the hot water heater.

Contact a Professional Plumber to Assist with Your Hot Water Issues

Adjusting the hot water heater temperature is a simple process, but it is important to follow the recommended temperature guidelines, adjust the temperature in small increments, and hire a professional plumber to ensure that the optimal setting is achieved. This will not only ensure your safety but also save you money on your energy bills.

Ensuring the optimal hot water heater settings is crucial for both safety and energy efficiency. Setting the hot water temperature too high can cause scalding, burns, and even fatalities, especially for vulnerable populations such as children and the elderly. It is also important to comply with the plumbing regulations, which recommend storing hot water at 60-65 degrees Celsius and providing it to sanitary fixtures at a maximum of 50 degrees Celsius.

To ensure the hot water heater is set to the recommended temperature, it is best to seek the services of a professional plumber who can adjust the settings accurately and safely. Attempting to adjust the hot water heater without the necessary knowledge and expertise can lead to further problems and potentially hazardous situations.

In summary, it is essential to prioritise the safety and wellbeing of your household and comply with the plumbing regulations by setting the hot water heater to the optimal temperature. By seeking professional plumbing services, you can ensure that your hot water heater is set to the right temperature, and your household can enjoy hot water without any risks or issues.
