Information on Energy Conservation for households that have a Fireplace

Energy Conservation

The reason for this is the amount of room air it takes to feed a
fire. You need a thrust of air to assist in the natural venting of
the fireplace, natural venting begins as soon as you open the
damper.

Now that homes are built so air tight, when you are running
your furnace your home appliances require exhaust and the
exhausted air needs to come from somewhere. At times it may
come back down the chimney causing smoke back up or a
negative air problem.

It also could be your furnace backing up and may cause a
carbon monoxide issue. Fire and exhaust systems will get the
air they need from the easiest source
