Chimney dampers create a tight seal on the top of chimneys, saving homeowner’s money by keeping energy in the home. Lindemann Chimney sells several kinds of dampers. Fan dampers are a nice option for homeowners because they allow for flexibility. Fans turn on and off to adjust for draft needs while the damper simultaneously ensures that conditioned air isn’t lost from inside the home when your fireplace isn’t being used. Throat dampers close of the chimney at the base, which keeps cold air that may gather in the chimney, from accessing the home. Spin dampers are designed for stoves and work well with older stoves that lack adequate air/inlet damper controls. Dampers drastically cut down on heating costs and keep your fireplace functioning properly.
