HOT WATER SERVICE MONITORING

摘要

A system includes a cold water supply, a water heater, a mixing valve, and one or more water use fixtures. The water heater includes a tank, a first temperature sensor configured to output a first temperature signal indicative of a water temperature of water in the tank, a heating device, and a water heater controller configured to control the water heater based on the first temperature signal and an operating temperature setting. The mixing valve outputs a mixed water flow, which is a combination of a hot water flow and a cold water flow, to the water use fixtures. A second temperature sensor outputs a second temperature signal indicative of a water flow temperature of the mixed water flow or the hot water flow, and a system controller selectively deactivates the water heater based on the second temperature signal.

1. A system configured to provide water service to one or more water use fixtures, the system comprising:
a cold water supply; a water heater comprising:
a tank containing a supply of water;a first temperature sensor configured to output a first temperature signal indicative of a water temperature of the water in the tank;a heating device configured to heat the water in the tank; anda water heater controller configured to control the water heater based on the first temperature signal and an operating temperature setting; a mixing valve configured to receive a hot water flow from the tank of the water heater and a cold water flow from the cold water supply, and output a mixed water flow, which is a combination of the hot water flow and a cold water flow; one or more water use fixtures configured to receive the mixed water flow; a second temperature sensor configured to output a second temperature signal indicative of a water flow temperature of the mixed water flow or the hot water flow; and a system controller configured to lower the operating temperature setting when the second temperature signal indicates that the water flow temperature exceeds a discharge temperature range.
