The benefits of a good water heater temperature
- Avoid burns: a temperature that is too high increases the risk of burns when using hot water.
- Limit bacterial proliferation: an appropriate temperature reduces the risk of bacteria such as Legionella, which is responsible for Legionnaires’ disease.
- Reduce limescale deposits: a water heater that is too cold promotes the buildup of limescale, which can damage and shorten the lifespan of the appliance.
- Save energy: every degree lowered can save up to 7% on the energy bill.
How to adjust the set temperature of your water heater?
To adjust the temperature of your water heater, you need to follow two steps.
First, locate the thermostat of the appliance where the potentiometer or adjustment disc is located.
Then, turn off the power supply and rotate the potentiometer (or pivot the disc) to reach the desired temperature.
Steps to adjust a modern water heater:
- Turn off the power supply of the water heater at the electrical panel.
- Locate the potentiometer, usually located near the control button of the appliance.
- Turn the potentiometer to adjust the temperature.
- Open a hot water faucet to check the temperature using a thermometer.

Maintaining a good temperature to prevent Legionnaires’ disease
To prevent the proliferation of Legionella bacteria, it is recommended to periodically raise the water temperature to over 60°C for about 30 minutes. This action should be performed regularly to ensure optimal quality of the sanitary water.
At what temperature should a water heater be set for optimal performance?
For optimal performance of a water heater, it is recommended to set the temperature between 55°C and 60°C. This temperature range ensures energy efficiency while minimizing potential risks associated with excessively hot water. It is advised not to exceed 60°C to avoid risks such as burns and the formation of limescale deposits.
By maintaining the temperature within this recommended range, you can benefit from optimal performance of your water heater while ensuring its safe use.
The water temperature in your home has a direct impact on your comfort, safety, and energy bill. By properly adjusting the temperature of your water heater, you will contribute to creating a healthy and cost-effective environment for your occupants. Follow our advice to fully enjoy all the benefits of a well-adjusted water heater.
Furthermore, don’t forget that savings are guaranteed by also optimizing the temperature of your refrigerator, which can contribute to a lower electricity bill.
