Question: how much would it cost to convert a wood burning fireplace to gas?
Answer: How Much Does It Cost to Convert a Wood Fireplace To Gas? It costs $100 to $300 to convert a gas fireplace to wood. Switching a wood fireplace to a gas insert is $2,280 to $4,030 because a flue has to be built and a gas line installed. A ventless gas fireplace will cost about $1,200 less to install.
