Energy efficient wood burning fireplaces
If you're adding a wood burning fireplace to your Metamora home, avoid the standard design, which sends too much of your home's heated air up the chimney. Consider these energy efficient wood burning fireplaces:
EPA rated fireplaces, have good performance and high energy efficiency ratings. They are designed to pull in outdoor air for combustion and circulate room air around the firebox to extract as much useable heat as possible.
Fireplace inserts, are sealed metal boxes designed to fit inside masonry fireplace openings. They use outside air for combustion and are designed to circulate and warm inside air. Make it more energy efficient by installing glass doors.
Energy efficient gas fireplaces
If you want the convenience and low maintenance of a energy efficient gas fireplace, you have 2 good options:
Direct vent gas fireplace, which use two-way vents that supply outside air for combustion, have energy efficiency ratings as high as 77%.
Vent free gas fireplaces, are even more energy efficient because they don't send exhaust outside. But they release a lot of moisture into inside air.
Certain states, may provide tax credits for various types of energy efficiency improvements, including fireplaces.
