If you were to hold a sheet of newspaper at the top of your fireplace frame, would the bottom end be sucked up the chimney flue? If the answer is yes, then you can see what is happening to all the heat in your house.
The CDE chimney damper is fitted below the chimney flue and above the flue starter. When the damper is in place and closed, no draught will enter the sitting room from the chimney, conversely no heat from your home will be sucked up the chimney. When the fire is alight you can half close the damper, this will counteract any down draught as well as reflecting a portion of the heat back into the room. It will also lessen the draw on the fire thus slowing the burning process and increasing the efficiency of one fire load of fuel. This will also reduce your carbon dioxide emissions as less energy from your central heating system will be required to adequately heat your house because no heat is being wasted due to an open chimney flue.
The main attraction of an open fire is its visual appeal, and many homeowners will insist on having an open fireplace. But with this comes some drawbacks, such as loud whistling noises, sooty hailstones or rain landing on living room rugs, heat being sucked out of the house even when there is no fire on, down draughts and cold ankle syndrome.
With the damper in place you simply close off the chimney flue when there is no fire on. This will then eliminate any howling wind noises, rain, hailstones and draughts entering or leaving your sitting room. You can then open the flue as and when you wish to light a fire and close it again once the fire is fully extinguished.
