The temperature of incoming ground water (cold water inlet temperature) varies greatly throughout the U.S. and also fluctuates with change of season. The temperature of water as it enters the water heater will determine the amount of “temperature rise” required to achieve the desired hot water outlet temperature (120°F is recommended). The best way to measure your incoming ground water temperature is to use a thermometer to measure cold water temperature during the coldest season of the year. To
