Gas Inserts are an economical and easy way to upgrade a regular fireplace to a gas fireplace.
Modern fireplace inserts are 75% more efficient than an open fireplaces. Open fireplaces are not that efficient as they pull already heated air out of the room, which is just a waste of energy, as well as a quick burning fire. Fireplace inserts are also sealed, reducing the amount of heat leaking out.
Gas Insert fireplaces also reduce your carbon footprint as you are burning gas, not wood, meaning your emissions are closer to zero than it would be with an open hearth fireplace.
