If you have an existing fireplace but want something new, getting a new fireplace insert or adding a gas log set can be viable options.
If ambiance is the goal, a traditional gas log, modern glass, or decorative rock burner can be added to your existing wood burning fireplace using the current firebox and flue. These systems look fantastic, but are not the most efficient.
If efficiency and heating are desired, a full insert may be the ticket. In this case, a full insert is slid into your existing wood fireplace with new venting run down your existing flue. These units use outside air for combustion making them much more efficient – capable of being used for both ambiance and additional heat. Full gas inserts come in a variety of traditional and modern styles.
