Prefabricated fireplaces, also known as zero-clearance fireplaces, are highly insulated, so they can be installed within an inch of combustible materials, such as wall framing. They are preferred in new construction because they`re much lighter in weight, are faster and easier to install than standard masonry units, and are energy-efficient. Many newer prefabricated fireplaces are prefabricated from metal and installed in wood-frame walls. They generally have a metal shell and a realistic brick-lined firebox. A wood stove is essentially a metal container for a fire. Made from cast iron or brick-lined, welded plate steel, a wood stove has an inlet for combustion air and an outlet for combustion gases, or smoke. Most modern wood stoves are airtight and allow the amount of combustion air that feeds the flame to be controlled. This control allows a wood stove to burn far more efficiently than a traditional open fireplace.
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.
