Direct Vent Gas Fireplaces
draw combustion air from the outdoors and vent directly through a wall without a masonry chimney. They can circulate heated air and be controlled by a thermostat. They are an energy efficient alternative to open fireplaces, which draw room air up the chimney - often removing more heat from the house than they produce.
Federal, local, or utility programs may offer incentives
for installing certain energy-efficient devices in your home.
