Is running a ventless fireplace better than running the heat?
On One Hand: It Is Better Than Running The HeatSince ventless gas fireplaces do not require a chimney, they can be installed almost anywhere in the house. They are very efficient, with almost 100 percent of potential heat being converted to useable heat, and are effective for zoned heating, in which you only heat part of your house to save money.On the Other: Concerns About Fumes, Water Vapor, Building CodesAlthough manufactures of ventless fireplaces claim they meet all air quality standards, consumers continue to worry about fumes being vented into the home instead of outside. Water vapor from the fire is vented into the home, which can result in condensation on windows and, in the long term, mold and mildew problems. In some states, ventless fireplaces are banned because they do not meet building codes.Bottom LineVentless gas fireplaces are efficient and effective for zone heating, which will save you money over whole-house heating.
