Is turning off the boiler at night really saving electricity
Turning off the boiler to save electricity is not only ineffective but also unsafe, experts warn. Keeping the boiler running continuously maintains the water temperature with minimal energy use, whereas frequent restarts after the water cools completely cause a significant increase in electricity consumption.

Frequent temperature fluctuations caused by switching the boiler on and off lead to the metal tank expanding and contracting, resulting in microcracks and shortening the equipment’s lifespan. Additionally, maintaining a temperature above 60°C is essential to prevent the growth of harmful bacteria that can develop when water cools regularly.
Therefore, to preserve health and extend the boiler’s durability, it is better to avoid constant switching off, even if it seems like it would save electricity.
