Abstract
Systems and methods are directed to water healer systems, including combi boilers and instantaneous water heaters, for initiating pre-heat and energy savings operations. Embodiments of the present invention can include at least one heat exchanger, a plurality of temperature sensors sensing water temperature at one or more locations within the water heater system, and a control system in communication with the first and second heat exchangers. In embodiments, the control system can be configured to at least: determine an expected demand for hot water, determine a target modulation rate based on the plurality of temperature sensors, and the expected demand, monitor the plurality of temperature sensors and a flow rate, and update the modulation rate based on at least one of a detected change in flow rate and a detected change in at least one of the plurality of temperature sensors.
