Maximize warmth, minimize waste

How to make your fireplace more energy efficient

Fireplaces evoke cozy winter memories, but did you know they can actually make your home colder? Here’s how to enjoy a glowing fire while keeping your home comfortable and energy efficient.

When a fire burns, warm indoor air rises and escapes through the chimney, drawing cold outside air into your home — a phenomenon called the stack effect. This is especially problematic in drafty homes. My dad’s rule of no fires on the coldest nights now makes sense: The greater the temperature difference between indoors and outdoors, the stronger the stack effect.

To minimize energy loss, close the chimney damper when the fire and ashes are fully extinguished. Leaving it open is like leaving a window ajar in winter. If your damper doesn’t close properly, consider purchasing a chimney plug — available in various styles — to fit snugly. Sealing air leaks around windows, doors and exterior walls with caulking and weatherstripping also helps.

Gas fireplaces with logs often require the damper to remain open for safety, allowing gases from the pilot light to escape. Installing glass doors can reduce drafts and air leakage year-round. Better yet, upgrade to a sealed combustion gas fireplace. These systems draw air for combustion from outside, providing warmth without heat loss.

Woodstoves and pellet stoves are efficient alternatives to traditional fireplaces, offering more heat. High-
efficiency biomass stoves even qualify for a 30% federal tax credit (up to $2,000) if installed by the end of 2032. Check for products with a thermal efficiency rating of 75% or higher at www.energystar.gov.

If you’re using a woodstove, fireplace or any fuel-burning appliance, install smoke and carbon monoxide
detectors to protect your family from the dangers of carbon monoxide — an odorless, colorless gas.

Finally, don’t forget summer maintenance. Turning off the gas pilot light can save energy, but follow your owner’s manual for safe procedures.

Take these simple steps to maximize fireplace efficiency, reduce waste and keep your home warm and inviting. After all, winter nights are best spent comfortably gathered around a glowing fire with loved ones.
