Hot water in the storage tank must be kept above 140 degrees Fahrenheit to prevent the growth of harmful bacteria. Yet water at this temperature would instantly scald and burn anyone putting their hand under it.  By mixing the hot with cold water, and monitoring the “set point” temperature carefully, these valves ensure that water at the desired set point is delivered to users at all times and under all load conditions.
