Automatic Vent Damper System | Gas Heat Flue Economizer
Automatic Vent Damper System | Gas Heat Flue Economizer. The automatic vent damper adds efficiency to water heaters and furnaces. The automatic flue damper traps heat in the furnace, boiler, or water heater. It holds heat in and around the heat exchanger instead of allowing it to rise up the flue.
The control voltage from the appliance powers the automatic vent damper. The automatic vent damper has a little motor that powers it to the closed position. It leaves all the heat trapped inside the furnace, boiler, or hot water heater. Prior to the existence of automatic vent dampers, the heat escaped up the flue and vented to the atmosphere. (more…)
