During routine maintenance, what is the recommended setting for the cylinder operating thermostat?

The recommended setting for the cylinder operating thermostat during routine maintenance is 58-60 degrees Celsius. This temperature range is significant because it effectively prevents the growth of harmful bacteria, such as Legionella, while also providing sufficient hot water for most domestic needs.

Setting the thermostat to this level helps to balance safety and efficiency. Higher temperatures can increase the risk of scalding and may lead to excessive energy consumption. Moreover, it ensures that the water remains at a temperature that can reduce the risk of bacterial growth without being excessively heated, which can cause wear and tear on the system over time.

Therefore, maintaining the thermostat within this range is essential for compliance with safety standards and to promote the longevity of the water heater system.
