Wood stoves built during the 1970s and early 1980s offer efficiencies of 50 to 60 percent. Those built since new governmental requirements were put in place in 1988 offer 75 percent or higher overall efficiency; that is, they convert up to 75 percent or more of their fuel into heat. Concern about particulate emissions or air pollution carried by wood smoke have also forced changes in wood stove designs. Although old wood stoves gave off up to 50 grams of particulates per hour in smoke, new certified stoves give off only about 5 grams. Most new wood stoves are energy efficient, environmentally friendly and come in many styles and colors. If you thought that wood stoves only came in black and belched smoke then think again. The new wood stoves are energy efficient, clean burning and there is a wood stove to fit any home or life style.
The top vent gas fireplace design can be installed into existing fireplaces and uses the metal or brick chimney as the exhaust vent. The combustion air for top vent fireplaces is drawn from inside the home while the chimney vents the exhaust gas. The vent-free gas fireplace model uses no exhaust vent. This style includes an oxygen-depletion sensor that turns off the gas if it senses a dangerous lack of oxygen inside the house. While fireplace manufacturers claim that vent-free fireplaces burn clean, are energy-efficient and don`t threaten indoor air quality, be aware that a number of states do not permit the installation of vent-free fireplaces. In the New England states of New Hampshire, Massachusetts, Vermont, Maine and Connecticut installation of vent-free gas fireplaces is permitted. Massachusetts has in the past not authorized the installation of vent free gas fireplaces for safety reasons.
