What is the typical temperature setting recommended for domestic hot water?

The recommended temperature setting for domestic hot water is commonly set at 60°C (140°F). This temperature is considered safe and effective for several reasons. Maintaining hot water at this level helps to prevent the growth of harmful bacteria, such as Legionella, which can thrive in lower temperatures. Additionally, 60°C provides a balance between scalding risks and energy efficiency, ensuring that hot water is readily available for household use while also mitigating the risk of burns.

Moreover, at this temperature, the hot water is effective for cleaning and sanitizing purposes, particularly in kitchens and bathrooms. It's hot enough to dissolve fats and kill germs on cooking surfaces and utensils. Setting the temperature too low increases the risk of bacterial growth, while temperatures beyond this can pose a significant scalding hazard, especially for children and the elderly. Thus, 60°C is the typical standard that balances safety, hygiene, and comfort in domestic settings.
