What’s the installation cost for a gas wall heater for a drafty room? Consider a gas wall heater or furnace which a heating contractor charges $1,095 to install. A handy homeowner can do the job for $470 and save 57 percent.

If your home has an inadequate heating system or poor heat distribution, you can install a built-in vent-free natural gas space heater. Connected to a permanent gas line, these mini-units work just like a full-size gas furnace. They are energy-efficient and solve the problem of the all-too-often cold bathroom or bedroom at the end of the hall. These heaters are ideal for a small room where space is at a premium because they can be installed on the floor or mounted on the wall.

All vent-free heaters certified by the American Gas Association have built-in safety pilot systems to shut off the flames if there is any interruption in the gas supply, or if they detect too little oxygen in the immediate area. Don’t locate it near a window or exterior door because the unit’s thermostat will kick on and off whenever it’s opened and closed causing it to operate less efficiently.

A heating contractor will charge $1,095 to install a 25,000BTU natural gas space heater and connect it to an existing gas line. This includes labor and material. Even though you can do it yourself for $470 and pocket a 57 percent saving, don’t. This is a job best left to a licensed professional. It involves measuring the pipe runs, “dry” installing the pipe and fittings, placing the unit in position, completing the connections and, finally, having it inspected by the building department In your area.
