How much space will it heat?

It is rated for roughly 1,000 square feet, but that assumes an open, well-insulated space. Garages and workshops with drafts will feel less coverage.

Does it need electricity?

No. Ignition runs on two D batteries, which are included, so it works during a power outage.

Is kerosene odor a problem indoors?

Yes, some odor is normal, especially at startup and shutdown. Use only clean K-1 kerosene and keep a window or vent cracked for ventilation.

How long does a tank last?

About 12 hours on a full 1.9-gallon tank, less on the highest flame setting.

What comes in the box?

The heater, a siphon pump for filling and two D batteries. Kerosene fuel is not included.

Can I use it in a tent or camper?

Only with serious ventilation. It is marketed for outdoor and jobsite use, but carbon monoxide risk makes enclosed spaces risky without airflow.
