A modulating heater system for a pool or spa includes a pool or spa heater capable of variably modulating energy output thereof and a controller communicatively coupled thereto. The controller determines a predicted load based on a previous load, ambient and water temperatures, and estimated pool/spa size, and determines an overshoot setpoint for an operational mode. The controller establishes a target temperature setpoint for the mode and receives a current water temperature. The controller determines whether the overshoot setpoint plus target temperature setpoint is greater than the current water temperature, and determines an error based thereon. The controller determines if the error is less than or greater than a target for the mode, and, based on this determination, determines a heater modulation rate for the mode taking into account the mode, maximum heater output, and available fuel supply. The controller controls the heater to operate at the determined modulation rate.
