They really are and also notoriously inefficient. Factor this into soaring energy costs, and you’ve got a good reason to transform a drafty fireplace into an efficient heating source.
What makes traditional fireplaces inefficient? Hot air rises, thus much of the air heated by the fire escapes through the chimney. When a fireplace isn’t in use, the draft pulls conditioned air from your home making your heating system work harder and energy bills rise.
How can you improve fireplace efficiency? Take measures to reduce heat loss via the chimney and to direct more heat into your home. Here are a few strategies:
Dampers: Most fireplaces have a throat damper - an iron plate that controls airflow. When the fireplace isn’t being used, keep the damper closed. And consider replacing it with a top sealing damper which mounts at the top of the chimney and seals tightly to eliminate drafts.
Firebacks: A cast iron or stainless steel fireback on the rear fireplace wall helps to radiate heat outward. And firebacks usually feature decorative designs that can enhance your home decor.
Doors: Tempered glass doors with adjustable air openings help maximize efficiency when your fireplace is in use. When it’s not, close the fireplace doors to keep warm air in your home.
Grate Heaters: These units are alternatives to conventional fireplace grates. They pull in air, heat it, and blow the heated air into the room. Some are even equipped with thermostats to automatically turn the fan on and off.
Inserts: Gas or wood-burning inserts are insulated systems that burn more efficiently and create greater heat output. Note: The EPA recommends that you have a certified technician install a wood-burning insert. Also check emission requirements in your area and have your chimney inspected and cleaned before installation.
As always, I appreciate the opportunity to provide energy-saving tips. This edition happens to arrive on a spare-the-air day so don’t experiment with burning today. Boost the efficiency of your fireplace so that it generates increased warmth as well as holiday ambiance at a lower cost too.
