Came out today to check the temperature of the hot water for the first floor. I took a temperature reading from the kitchen sink and got a reading of 121°F. I set the hot water heater for the Lowest setting and removed some of the hot water. Took a second reading using 2 different temp probes and the readings were 100°F and 101°f. I observed the hot water heater to see if it would fire up to heat the water. The hot water heater is maintaining the temperature of 100°f. The system is operating properly at this time. Bill out per office.
