Do you love your fireplace? If so, you’re not alone. There’s nothing quite like curling up by a crackling fire and watching big, fluffy flakes drift outside the window, after all.  But fireplaces can be huge energy wasters.  Although open fireplaces have been used for centuries to heat family homes, they’re actually rather inefficient in modern houses. Up to 90% of the home’s heat goes up the chimney with the smoke. Adding glass doors may increase efficiency, but it’s only by 20%. Gas fireplaces and wood stoves are more energy-efficient options. If the charm of an indoor fire appeals to you, Bob Vila has some facts, alternatives and links to helpful articles in his radio spot.  When done right, adding a little toasty romance to your home won’t add to your heating expenses.
