Abstract
A water heater having of a tank defining a storage space for water. A heat source in a combustion chamber is operable to heat water in the storage space and has a first state and a heating state. A flue is part of a gas flow passage through which combustion gases are communicated towards a first location. A flue damper has closed and open states. A powered device in an on state induces flow of combustion gases from the combustion chamber towards the first location. A control is configured to: a) process a user input identifying a target output water temperature and generate a call for heat; and b) in response thereto i) cause the powered device to change from its first state; ii) cause the flue damper to change from its closed state towards its open state; and iii) cause the heat source to change from its first state into its heating state.
