    Abstract: A method for detecting and compensating for sediment build-up in a tank style water heater is disclosed. An illustrative but non-limiting example may include monitoring a temperature of water within a water storage tank of a water heater over time, resulting in a monitored temperature profile. The method may then include determining if the monitored temperature profile includes one or more features that indicate sediment build up in the water storage tank, and if so, provide an output that indicates sediment build up is present.

    Abstract: A locally powered intermittent pilot combustion controller may include an igniter, a thermal electric and/or photoelectric device that produces an electrical signal having power when exposed to a flame, and a local power source for providing power when the thermal electric and/or photoelectric device is not exposed to a flame. In some cases, the intermittent pilot combustion controller may include a memory for storing information about an ignition sequence for igniting a pilot flame, and a controller coupled to the memory. The controller may be configured to initiate the ignition sequence of the pilot flame using information stored in the memory, determine whether the ignition was successful by monitoring the electrical signal produced by the thermal electric and/or photoelectric device, and adjust the information stored in the memory based on whether the ignition sequence completed successfully.
