A gas insert is just that – an “insert” into an existing open hearth. Many people who have had a wood-burning fireplace for years come to us because they seek a gas option with less mess and higher heating efficiency. A gas insert is perfect for this situation because of the existing hearth and flue.
Gas inserts sit inside a metal box contained within a larger metal box that goes into the existing fireplace and usually has a trim surround to finish the opening. Heat is generated in between these two boxes and then heat is emitted from the firebox. Since gas inserts produce radiant heat and a steady stream of warm air, they are a great option to heat the home.
