A Lock-Top damper or energy-saving damper is a damper that is connected to the chimney system at the top of the flue. Like a throat damper, it has an easy-to-use cable for opening and closing the flue (donât worry â you wonât have to go up on the roof!), but unlike a throat damper, a Lock-Top damper provides an airtight seal.
A vent damper is an automatic devise that shuts off the flue pipe when the burner is not running. A vent damper has no effect on the running efficiency of the appliance. It only saves off-cycle losses of heated air. Therefore, if the appliance is in an unheated space, there is no benefit to a vent damper. A vent damper can achieve up to 10% annual fuel savings.
