The temperature of water heating is not so much a question of habits as it is a question of competent energy management.
Why is it important to choose the right temperature?
Heating water to 70–80°C uses much more energy than at a moderate 50–60°C. In addition, hot water cools down faster, and more heat is lost through the walls of the tank, which makes heating even less efficient.
Research shows that the optimal temperature for a water heater is considered to be 55°C – it provides:
- reasonable energy consumption;
- destruction of bacteria, including legionella;
- reduced risk of scale formation on heating elements.
How does this affect the budget?
Lowering the temperature from 70°C to 55°C can reduce energy consumption by 10–15% , which, if the boiler is used regularly, will result in significant savings over the course of a year.
What can be done in practice
- Set the thermostat to 55°C.
- Use a timer: Let your boiler run at night if you have a discounted rate (eg 3am to 7am).
- Perform preventive maintenance once a year – scale reduces efficiency and accelerates wear of the device.
Conclusion
Setting a reasonable temperature is not only a matter of wallet-friendliness, but also a way to extend the life of your equipment and reduce the load on your energy system. For most families, 55°C is the sweet spot between comfort and economy.
