As of 2015, prices for direct vent gas stoves typically range from $1200 to $4500, according to home heating website Hearth. Additionally, installation costs range from $700 dollars to more than $5000, depending on the complexity of the installation.
Direct-vent gas stoves use efficient combustion processes to produce cooler exhaust gases than conventional gas stoves. This simplifies installation of the stove and makes it cheaper, since it allows for plastic pipe to route exhaust gases out of the interior of a structure, rather than a chimney. Since direct-vent gas stores are also more efficient than conventional stoves, these stoves usually save consumers on fuel costs over the long run versus conventional stoves.
