Our Verdict

This heater uses natural gas to produce 20,000 BTU of heat. It covers up to 950 sq ft. That puts it far above most electric space heaters in raw heating power.

You need no electricity to run it. It keeps working when the power goes out. This is a real advantage in cold weather emergencies.

The ODS sensor watches oxygen levels in the room. It shuts the heater off before levels become unsafe. This is a critical built-in protection for any indoor gas appliance.

The thermostat gives you three heat settings: Low, Medium, and High. But there is no timer and no remote control. You must walk to the unit each time you want to adjust it.

This heater needs a natural gas line already in your home. It does not plug into a wall outlet. Confirm your home has a gas connection before you buy.

What We Like

  • Produces 20,000 BTU and heats up to 950 sq ft in one unit.
  • Runs on natural gas with no electricity needed, including during power outages.
  • Built-in ODS sensor shuts the heater off automatically if indoor oxygen levels drop.
  • Includes both wall mount hardware and floor base feet in the box.
  • ANSI certified for safety with a simple push-button ignition system.

What Could Be Better

  • No tip-over protection despite including a floor base stand option.
  • No timer function to schedule heating or set an automatic shutoff.
  • No remote control means you must walk to the unit to change any setting.
  • Requires a permanent natural gas line, which limits where you can place it.
  • No oscillation or fan sweep to spread warm air evenly across a room.
