How to Make a Fireplace More Efficient

The efficiency of a fireplace depends on several factors. Though the design is certainly important, it isn't the only thing to consider. Adding components and performing routine maintenance are critical to maximizing efficiency. No matter what type of wood you're burning, you must have sufficient airflow and a quality firebox to get the most heat out of your fireplace. Otherwise, you're just throwing your money away.

Things You'll Need

• Flashlight
• Wire brush
• Glass doors
• Chisel
• Ball peen hammer
• Fireplace mortar
• Caulking gun
• Metal smoke guard
• Outside air vent kit

Instructions

1. Make sure your damper is in good working condition as poor air intake will cause your fire to just smolder. Use a flashlight to see if the plate is out of its track. If so, remove it, clean off the debris with a wire brush and then re-install the damper properly on its track.

2. Install glass doors on the front of your fireplace to improve the draft. By regulating the airflow, you can reduce the loss of heated air that goes up the chimney.

3. Repair the mortar joints in the brickwork. Chip away any damaged mortar with a chisel and ball peen hammer then use a caulking gun loaded with fireplace mortar to refill the joints. Smooth with a putty knife and make sure it sets for at least 24 hours before use.

4. Reduce the size of the fireplace opening by installing a smoke guard. A spring loaded model is best as you can custom fit it to the width of your fireplace opening.

5. Add an outside vent to boost the draft and create a more efficient burn. These are sold as kits and include a floor register you install a few feet from the fireplace, connected to an air inlet on the outside of the house by a flexible hose.

6. Inspect your chimney annually to ensure there are no obstructions. Open the damper and shine a flashlight up the flue. Clear out any debris you find.
