What is the recommended temperature setting for a thermostatic mixing valve?

The recommended temperature setting for a thermostatic mixing valve is typically around 50°C (122°F). This temperature is designed to balance safety and comfort. At this setting, the risk of scalding is significantly reduced, especially for vulnerable populations such as children and the elderly, while still providing sufficient hot water for sanitation and other household uses.

This temperature allows for effective control in domestic hot water systems, ensuring that the output is warm enough for bathing and washing without exceeding safe limits that could cause burns. Therefore, setting the thermostatic mixing valve to this temperature supports both the health and safety considerations and the practical needs of hot water delivery in various applications.
