Abstract

Apparatus for improving the efficiency of a water heater includes a combination damper assembly and heat transfer baffle. The damper assembly includes a plurality of movable damper with each damper leaning outwardly from one another when the dampers are in a closed position. The baffle depends from the damper assembly and includes a truncated conical shape in this position within the flue of a water heater for directing combustion gases from the burner against a flue wall.
