Constant temperature changes caused by turning off and on the boiler cause expansion and contraction of the metal tank, which leads to the formation of microcracks and shortens the service life of the equipment. In addition, keeping the temperature above 60°C is critical to prevent the growth of harmful bacteria that can develop when the water is regularly cooled.

Therefore, in order to preserve the health and longevity of the boiler, it is better to avoid turning it off constantly, even if it seems that this will save electricity.
