Our Verdict

This heater pushes out 23,800 BTU. That covers 1,000 square feet. Few portable heaters match that kind of raw output.

It runs without electricity. That makes it useful when the power goes out. Garages and workshops are where it performs best.

Safety coverage is only partial here. Tip-over protection is included. But there is no overheat protection, which most competitors provide.

There is no thermostat. You set the heat level and watch it yourself. This takes more attention than most modern heaters require.

Kerosene is an ongoing cost. You need to buy and store fuel each season. Factor that into your total budget before buying.

What We Like

Heats up to 1,000 sq ft, covering spaces twice the size of most portable heaters.
23,800 BTU output ranks among the highest available in portable indoor heaters.
Runs on kerosene with no electricity, so it keeps working during power outages.
Tip-over protection shuts the unit off automatically if it falls.
Portable form factor lets you move it between rooms or locations with ease.

What Could Be Better

No thermostat means you cannot set a target temperature and let the heater manage itself.
No overheat protection, a standard safety feature found on most competing heaters.
No timer requires you to manually turn the heater on and off every time.
No remote control means all adjustments must be made by hand directly at the unit.
Kerosene fuel adds ongoing purchase and storage costs on top of the $205 purchase price.
