REMOTE LEAK AND FAILURE DETECTION OF ELECTRICAL WATER HEATERS THROUGH TEMPERATURE AND POWER MONITORING

An aggregator is in operative communication with an aggregation of electric water heaters to receive thermostat readings and power consumption readings from the electric water heaters and to communicate demand response dispatch signals to the electric water heaters. The aggregator performs operation...

Zusammenfassung:	An aggregator is in operative communication with an aggregation of electric water heaters to receive thermostat readings and power consumption readings from the electric water heaters and to communicate demand response dispatch signals to the electric water heaters. The aggregator performs operations including: responding to instructions for a desired demand response by generating the demand response dispatch signals for the electric water heaters so as to cause the aggregation to draw electrical power providing the desired demand response; and determining whether an electric water heater of the aggregation has a failure and generating a notification of the failure. The determining including at least one of: determining whether the electric water heater has a failed heating element based on the thermostat readings received from the electric water heater; and determining whether the electric water heater has a water leak based on the power consumption readings received from the electric water heater.
