A method of controlling a modulating water heater supplying water to a system includes sensing a parameter which changes corresponding to a change in system flow rate, the sensed parameter being a parameter other than system temperature, and then modulating output of the heater in response to a change in the sensed parameter. Early detection of system flow rate changes permits early modulation of water heater output before the changes in flow rate have had time to significantly impact the system temperature. |
