Our Verdict

This heater puts out 12,000 BTU of natural gas heat. It warms up to 300 sq ft without electricity. It works great when the power goes out.

Infrared technology warms objects in your room directly. You get completely silent operation with no fan noise. The LOW-HI control knob makes heat adjustment simple.

You mount this unit on your wall. It stays off the floor and out of the way. This removes the tip-over fire risk of portable heaters.

You get no timer or remote control here. You must walk to the heater every time you adjust settings. This limits daily convenience.

Natural gas costs much less to run than electricity. At 12,000 BTU, you heat a full room very cheaply. Your long-term savings make the $133 price reasonable.

What We Like

  • 12,000 BTU natural gas output heats up to 300 sq ft, delivering the heat equivalent of a 3,500W electric heater.
  • Runs with zero electricity, making it a reliable backup heater when the power goes out.
  • Infrared technology operates completely silently with no fan noise at all.
  • Built-in thermostat with LOW-HI variable knob lets you set your exact comfort level.
  • Wall-mounted design keeps your floor clear and removes all tip-over fire risk.

What Could Be Better

  • No timer means you must turn the heater on and off manually every single time.
  • No remote control forces you to walk to the wall unit every time you adjust the heat.
  • Runs on natural gas only with no propane conversion option, so homes without gas lines cannot use it.
  • The coverage-boosting fan (model WHF100) costs extra and is sold separately.
  • No built-in fan or oscillation, so even heat distribution depends entirely on your room's natural airflow.

Standout Features

12,000 BTU Natural Gas Output
Delivers the heating equivalent of a 3,500W electric heater. Most portable electric space heaters max out at 1,500W (5,118 BTU), making this unit more than twice as powerful.
Zero Electricity Required
Unlike nearly all space heaters that require an outlet, this unit runs purely on natural gas. It keeps heating during power outages when all electric competitors go dark.
Noiseless Infrared Operation
Produces zero fan noise. Most electric heaters with fan-forced heat generate 40 to 60 dB of continuous noise, making this a quieter option for noise-sensitive spaces.
