Abstract
A water heater includes a water tank adapted to contain water; a flue extending through the water tank and having a first end communicating with the water heater's combustion chamber for the flow of products of combustion through the tank; a damper communicating with the flue; and an apparatus for creating a flow of air proximate the second end of the flue to resist the flow of warm air out of the second end of the flue due to standby convection.
