The tempering valve has a temperature-sensitive element that mixes hot and cold water at an adjustable ratio and then is piped to the bathrooms or house. The hot water mixing valve mechanism is a sliding valve within the tempering valve that works to vary the ratio of hot and cold water allowed to pass. Hot water stored in a hot water storage system should be kept at a minimum temperature of 60°C. However, water should be delivered through a faucet at a maximum of 50°C. It also maintains a constant outlet temperature, reducing the risk of accidental scalding and bacterial infection in your storage tank.
