Unlike open wood burning fireplace or old decorative gas fireplaces, today’s gas fireplace inserts are heat-producing dynamos that use propane or natural gas to fuel a steady flame on realistic looking logs, decorative modern glass chips, or stones behind a sealed glass face.
Gas inserts for fireplaces can be used in masonry or prefab fireplaces; they can be vented through the existing chimney (or a wall for a free-standing unit).
Gas is the easiest fireplace insert to use and needs very little maintenance. Flip a switch; have fire. Its best application is for zone heating—turning up the gas in the room you’re in and lowering the thermostat in the rest of your house.
Green Factor: 58% to 85% efficiency rating; very little pollution, smoke, ash, or creosote. Zoned heating allows you to reduce overall fuel consumption.
Ventless versions burn very clean — they have to, because they also release pollutants into your home. In fact, some states don’t allow ventless systems.
Because fuel prices change constantly, any saving measurements are a moving target. Roughly speaking, yearly savings could range from $64-$255 (based on an average heating bill of $638) if you use an insert for zoned heating and turn down your thermostat.
