1. A beverage maker, comprising:
a heating system;
a temperature sensor operably coupled to the heating system;
a controller configured to receive measured temperature signals from the temperature sensor; and
a tangible, non-transitory computer-readable storage medium having instructions stored thereon for that, in response to execution by the controller, cause the controller to perform operations comprising:
receiving, by the controller, a series of measured temperature signals from the temperature sensor;
calculating, by the controller, a change in temperature using the series of measured temperature signals;
determining, by the controller, an expected change in temperature using a system thermal model;
comparing, by the controller, the change in temperature to the expected change in temperature;
accessing, by the controller, previous heating system performance data stored in the heating system performance database;
comparing, by the controller, the change in temperature to the previous heating system performance data stored;
calculating, by the controller, an efficiency of the heating system based on the change in temperature;
estimating, by the controller, a scale buildup based on the efficiency of the heating system; and
storing, by the controller, at least one of the estimated scale buildup or the efficiency of the heating system in a heating system performance database.
