A nice fire in the fireplace can help create the perfect atmosphere in a room on a cold winter night during the holidays. While most of us enjoy such a scene, it’s important to note that your fireplace can be costing you money when it’s not in use. If you don’t keep the flue damper closed heat can disappear up the chimney. The damper is located inside the chimney flue and must be open when you have a fire and should be closed when there is no fire, usually using a handle, lever or chain attached to the damper.
There are some helpful tips on our website about keeping the heat in your home and saving money on your utility bill by closing the damper when the fireplace is not in use. Those tips include:
- Wear dishwashing gloves while checking the flue and damper to help keep your hands clean.
- If your flue damper has a loop, you can hang a small sign, piece of ribbon or even the fireplace poker from it to remind you when the flue is closed.
- If you don’t have a damper or the one you have doesn’t fit properly, there are inflatable flue plugs available online to close off the flue.
- An open flue not only sends your heat up the chimney in winter but will also vent cool air from your home during the summer.
It’s important to note that there’s more to that roaring blaze than meets the eye. While it gives off heat immediately in front of the fireplace, the heat going up the chimney is actually causing cool air to be drawn into your home through cracks and leaks normally found around windows, doors and wall penetrations for plumbing and electric outlets. That cold air then needs to be warmed by your home’s heating system.
