What is the right Hot Water Temperature?

The appropriate hot water temperature for your home needs to be set at certain temperature for plumbing fixtures such as sinks, showers, etc. Some of this depends on the age and health of the individuals in the household. However, in general, the recommended hot water temperature is between 120 Fahrenheit or 49 degrees Celsius.

Water that is too hot can cause burns and scalds, especially in children, the elderly, and those with sensitive skin. On the other hand, water that is not hot enough may not effectively kill bacteria and other pathogens such as legionaries disease which can pose a serious risk to your health.


Legionella bacteria thrive in warm water environments, such as in hot water tanks, cooling towers, and large plumbing systems. If a water tank is not properly maintained, such as through regular cleaning and disinfection, Legionella bacteria can grow and potentially cause Legionnaires' disease, a type of pneumonia that can be severe and sometimes fatal. Symptoms of Legionnaires' disease can include fever, chills, cough, muscle aches, and shortness of breath. To prevent Legionella contamination in water tanks, it is important to practice proper maintenance and cleaning procedures, such as flushing and cleaning the tank regularly, maintaining appropriate water temperatures, and using appropriate water treatment methods. It is also recommended to seek the advice of a qualified professional for water tank maintenance and disinfection.



To help ensure that your hot water is at a safe and comfortable temperature, consider the following tips:

  1. Check your water heater's thermostat: Make sure that your water heater is set to a temperature is at 120 degrees Fahrenheit at the fixtures in your home.

  2. Use a thermometer: Use a thermometer to test the temperature of your hot water at the tap, and adjust the temperature accordingly.

  3. Consider a thermostatic mixing valve: A thermostatic mixing valve can help ensure that your hot water is delivered at a consistent and safe temperature.

  4. Educate your family: Teach your family members about the risks of hot water burns and scalds, and encourage them to be cautious when using hot water.

By following these tips, you can help ensure that your hot water is at a safe and comfortable temperature for you and your family.
