The average installation cost of a fireplace depends on many factors. The price can range from $300 to $12000 or more, depending on the model. Most ethanol, gel, gas, and electric fireplaces range from $500-$2500 for the current unit . Installation costs will, however, vary based on various factors. Electric Fireplace Costs It is the easiest to install and the most affordable option. The electric fireplace installation will range from as little as $300 to $12,000. Installation costs will vary based on the framing work required, adding to the overall cost. Gas Fireplace Costs On average, a gas fireplace will cost around $1500-$2500 to buy it. This will vary based on whether you choose an unvented, insert, or direct-vented model. It may cost more to install than buying it, especially if you do not have an existing gas line and construction is needed. Installation costs can therefore range from $500 to $2500 or more. Wood-Burning Fireplace Costs Of the three options, wood-burning fireplaces have the most expensive installation costs. This is because they must be professionally installed, and the prices will range from a few thousand dollars to more than $10,000. Venting is also quite expensive; hence the costs will be higher than the fireplace itself. For the basic unit, the price will be $2000-$10,000, while the freestanding stoves will cost up to $3200.
