Our Verdict
This heater puts out 23,800 BTU and covers up to 1,000 square feet. That is big power for large or hard-to-heat spaces. One tank runs it for up to 12 hours.
It uses kerosene, not electricity. You must have fuel on hand and proper ventilation nearby. Kerosene operating costs are higher than running a standard electric heater.
The biggest advantage is that it works without a power outlet. This makes it useful during outages or in garages and workshops with no electrical access. Tip-over and overheat protection add a layer of safety.
It has no thermostat, timer, or remote control. You adjust it manually every time. Most electric heaters at similar prices include at least one of these features.
At $269.99, you pay more upfront than most portable electric heaters. But your cost per square foot of heating is just $0.27. That is a good value if you need to heat a large area.
What We Like
- Heats up to 1,000 sq ft with 23,800 BTU output.
- Runs 9 to 12 hours on one full tank of fuel.
- Works without electricity, so it keeps you warm during power outages.
- Electronic ignition starts the heater fast and easily.
- Tip-over and overheat protection both shut it off if something goes wrong.
What Could Be Better
- No thermostat means you cannot set a target temperature automatically.
- No timer so you must turn it on and off by hand every time.
- No remote control requires you to walk up to the heater to adjust it.
- Kerosene fuel costs add up each season on top of the $269.99 purchase price.
- No oscillation, so heat does not spread as evenly as heaters with rotating airflow.
