How large a space will it heat?

At 23,800 BTU/hr it suits a large room, garage or open floor. In a well-insulated space it can carry a two-car garage; in a drafty one, expect it to take the edge off rather than fully heat it.

Does it need electricity?

No. A battery igniter lights the burner, so it runs without an outlet. Keep spare batteries on hand, since a dead igniter means no start.

How long does a tank last?

The 1.9-gallon tank gives about 9 to 12 hours, depending on the heat setting. Running full blast shortens that.

Can I use it indoors?

Kerosene forced-air heaters are meant for ventilated spaces like garages and workshops. Do not use one in a sealed living area; fumes and carbon monoxide build up.

What fuel does it take?

Clean, clear K-1 kerosene. Avoid diesel or contaminated fuel, which clogs the wick and worsens the smell.

How does it compare with a propane heater?

Kerosene gives long, steady heat without a power source, but it smells and needs wick care. Propane heats faster and burns cleaner but needs cylinders and, for blowers, electricity.
