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 if it a free standing unit, through a wall.
Gas inserts are the easiest inserts to use and they need very little maintenance. Flip a switch, start the fire. Its best application is for zone heating-heating up the room you’re in or heating a room that isn’t warmed sufficiently by your heating system.
Gas inserts can have up 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 there do not use chimneys.
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.
