How do you adjust a hot water temperature control valve?

To adjust the mixed outlet temperature of the valve, remove the cap to gain access to the adjusting spindle. The spindle should be rotated-clockwise to reduce the temperature, counter-clockwise to increase the temperature until the desired set point is reached.

What should hot water temperature be from the tap?

The American Society of Sanitary Engineering recommends that hot water tanks be set from 135 to 140 degrees, to inhibit the growth of Legionella bacteria, with the installation of anti-scald devices and tempering valves to prevent hot water injuries.

What temperature should hot water tap be UK?

60 °C
Hot water should be stored at 60 °C at least in order to kill legionella bacteria. The thermometer pocket at the top of the cylinder and on the return leg, if fitted, is a useful point for accurate temperature measurement.

Why is my hot water suddenly scalding hot?

If your water heater is making hot water too hot all of a sudden, it’s likely the result of the temperature setting being too high, a malfunctioning thermostat, high mineral content, or the pressure relief valve is blocked. Each of these issues can cause the water from the faucet to come out too hot.

How does a hot water heater regulator work?

Water heaters have a special type of water pressure regulator which is called a temperature pressure regulator valve (TPRV or TPR valve). The TPR valve is designed to open if the pressure or temperature inside the hot water heater grows to a dangerous level, allowing the pressure to vent harmlessly, albeit sometimes messily.

What is the standard temperature for hot water?

The ideal temperature for household hot water is 120 degrees Fahrenheit, while the tank itself should be around 130 degrees F.
