Abstract
Methods, apparatus, and system for predicting the availability of hot water for bathing. One or more parameters corresponding to the operation of a water heater are monitored over time and/or a temperature distribution of water in a hot water tank measured. Data corresponding to the monitored parameters and/or temperature distribution are processed to determine a rate at which hot water is being consumed by filling a bath and/or due to other hot water consumers and/or to determine a current hot water availability condition. Based on a hot water consumption rate and/or determination of a current hot water availability condition, a projection is made to whether there will be adequate hot water to fill the bathtub to a desired level or volume at a desired temperature.
