Water heater operation monitoring and notification
A water heater monitoring and notification method includes determining, by a controller of a water heater system, a deviation of a duration of a pre-purge operation from a pre-purge duration average value. The method further includes determining, by the controller of the water heater system, a deviation of a flame current from a flame current average value and determining, by the controller of the water heater system, a deviation of a pulse-width-modulation (PWM) parameter from a PWM parameter average value. The method also includes providing a notification related to a combustion system of the water heater system based on at least the deviation of the duration of the pre-purge operation from the pre-purge duration average value, the deviation of the flame current from the flame current average value, and the deviation of the PWM parameter from the PWM parameter average value.
1. A water heater monitoring and notification method, comprising:
determining, by a controller of a water heater system, a deviation of a duration of a pre-purge operation from a pre-purge duration average value;
determining, by the controller of the water heater system, a deviation of a flame current from a flame current average value;
determining, by the controller of the water heater system, a deviation of a pulse width modulation (PWM) parameter from a PWM parameter average value; and
providing a notification related to a combustion system of the water heater system based on at least the deviation of the duration of the pre-purge operation from the pre-purge duration average value, the deviation of the flame current from the flame current average value, and the deviation of the PWM parameter from the PWM parameter average value.
2. The method of claim 1 , further comprising determining, by the controller of the water heater system, a ratio of a number successful ignition cycles of the combustion system to a number of total ignition cycles.
3. The method of claim 2 , wherein the notification is provided further based on the ratio of the number successful ignition cycles of the combustion system to the number of total ignition cycles.
4. The method of claim 3 , wherein the notification indicates that the combustion system is in a good working condition.
5. The method of claim 3 , providing a second notification based on at least the deviation of the duration of the pre-purge operation from the pre-purge duration average value, the deviation of the flame current from the flame current average value, the deviation of the PWM parameter from the PWM parameter average value, and the ratio of the number successful ignition cycles of the combustion system to the number of total ignition cycles, wherein the second notification indicates that the combustion system is in a sub-optimal working condition.
6. The method of claim 3 , providing a second notification based on at least the deviation of the duration of the pre-purge operation from the pre-purge duration average value, the deviation of the flame current from the flame current average value, the deviation of the PWM parameter from the PWM parameter average value, and the ratio of the number successful ignition cycles of the combustion system to the number of total ignition cycles, wherein the second notification indicates that the combustion system requires service.
7. The method of claim 1 , wherein the notification is provided via a display interface of the water heater system or transmitted wirelessly or via a wired connection.
