Does a lack of heat keep you from using spaces like the garage, a workshop or basement during the winter? A natural gas space heater can provide a convenient and affordable solution.

VENT-FREE wall heaters (starting at $120) are the most compact space heaters. They use oxygen from the room and vent directly into the room. Blue flame heaters are the most energy-efficient, but are not ideal for rooms with high ceilings. Infrared heaters are a good choice for larger rooms and those with high ceilings.


Space Heater
  • Available in 6,000, 10,000, 20,000, and 30,000 BTU ranges.
  • Wall mount or free standing.
  • Sensor shuts down the pilot light if low oxygen level is detected.
  • Pricier models have thermostat controls.
  • Optional accessory blower (requires 120-volt power source) can quickly distribute warm air.

DIRECT-VENT wall furnaces (starting at $650) can heat more square footage than vent-free models. A burner heats air inside a completely sealed combustion chamber. The chamber then heats the surrounding metal cabinet, which radiates heat to the room.

All models include a venting system, which requires the unit be mounted to an outside wall of the home. These heaters feature near silent operation and can connect with a wall thermostat.

B-VENT wall furnaces (starting at $900) draw air from the room for combustion and vent the fumes to the outdoors. They do not require installation on an exterior wall. These wall units are generally similar in appearance and options to direct-vent wall furnaces.


No matter which model or style of natural gas space heater you choose, professional installation is necessary for safety. You’ll need a professional installer to connect the unit to your existing Walton Gas line and install a ventilation system, if one is required. And don’t forget to also install a carbon monoxide detector in the room where your new space heater is located.
