Abstract
Apparatus for improving the efficiency of a water heater having a tank, a burner and a flue, the flue being disposed within the tank for evacuation of burned combustion gases therethrough with resulting heating of water in the tank, generally including combustion gas deflector for enhancing heat transfer from the combustion gases through a flue wall and into surrounding water during ignition of the burner, a vent damper for preventing ambient air in the flue, heated by the directing means and flue, from escaping the flue during nonignition of the burner.
Claims11
Apparatus for improving the efficiency of a water heater having a tank, a burner and a flue, said flue being disposed within said tank for evacuation of burned combustion gases therethrough with resulting heating of water in said tank, said apparatus comprising:
- combustion gas directing means for enhancing heat transfer from the combustion gases through a flue wall and into surrounding water when said burner is on, said combustion gas directing means comprising a plurality of separate nestable segments;
- and
- vent damper means for preventing ambient air in the flue, heated by the directing means and flue, from escaping the flue when said burner is off.
Water heater apparatus comprising:
- a tank;
- a burner;
- flue means, disposed in said tank, for evacuation of burner combustion gases therethrough with resulting heating of water in said tank;
- combustion gas directing means for enhancing heat transfer from the combustion gases through a flue wall and into surrounding water when burner is on, said combustion gas directing means comprising a plurality of separate nestable segments;
- and
- vent damper means for preventing ambient air in the flue, heated by the directing means and flue, from escaping the flue when said burner is off.
Apparatus for improving the efficiency of a gas water heater having a tank, a burner and a flue, said flue being disposed within said tank for evacuation of burner combustion gases therethrough with resulting heating of water in said tank, said apparatus comprising:
- combustion gas flow controlling means, sized for disposition within said flue, for enhancing heat transfer from the combustion gases through a flue wall and into surrounding water when burner is on, said combustion gas directing means comprising a plurality of nestable segments;
- and
- vent damper means for preventing ambient air in the flue, heated by the directing means and flue, from escaping the flue when said burner is off.
