There are three different styles of gas fireplaces: the direct vent model, the top vent design, and the vent-free model. The direct vent gas fireplace uses two vent pipes that lead directly to the outside. One pipe uses combustion air from the outside while the other vents the exhaust gas. 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 dont 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.
Fireplace Inserts If you have a masonry fireplace but dont like the associated, draftiness, energy costs or overall inefficiency, you should consider purchasing a fireplace insert, sometimes referred to as a fireplace stove insert. A fireplace insert is basically a wood stove designed to fit into a fireplace. Fireplace inserts are usually constructed of cast iron or steel just like wood stoves. Installing a fireplace insert will typically require the installation of a chimney liner. The chimney liner essentially narrows and insulates the chimney vent and connects directly onto the fireplace insert creating a closed highly efficient system. No more opening and closing the damper. Fireplace inserts can use various fuel options and are clean burning (minimal smoke and particulate emissions). Fireplace inserts like wood stoves are heavy, usually weighing upwards of 300 pounds. This means delivery and installation are better left to certified installers or professional chimney sweeps.
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.
Improve your fireplaces heat efficiency by 25% or more just by doing a few simple things, you can improve the efficiency of your fireplace and get more heat out of your fireplace, while enjoying the ambience and beauty of a wood-burning fireplace that is already in your home. If you have a little working knowledge of fireplaces, then you can understand why improving the amount of heat that a fireplace puts out is important to the over all enjoyment of having a fireplace in your home. If you are new to burning real wood-burning fireplaces, there are some very simple ways to improve the amount of heat that your fireplace will produce.
