Claim One:
1. A system, comprising: a boiler to heat a liquid; an enclosure in which the boiler operates; and a subsystem to determine scaling in the boiler, the subsystem comprising: a first temperature sensor to sense a temperature of the liquid in the boiler; a second temperature sensor to sense an enclosure temperature; a power sensor to sense power input to heat the liquid in the boiler; communication circuitry to receive, as sensor data, the temperature of the liquid from the first temperature sensor, the enclosure temperature from second temperature sensor, and the power input from the power sensor; and boiler monitoring circuitry to determine a rate of heat transfer and an amount of scaling in the boiler, the amount of scaling being determined based on the rate of heat transfer, the rate of heat transfer being determined based, at least in part, on the temperature of the liquid, the enclosure temperature, and the power input to the boiler.
