Does it need electricity to run?

No. It burns kerosene from its own tank, so it works during a power outage. The flame controller and fuel gauge are mechanical.

How long does one tank last?

The 4.3L tank runs up to 16 hours at the lower burn rate. At the higher rate of about 0.26 L/h, expect closer to 16 hours or a bit less.

How much space will it heat?

Koolee rates it for 140 to 160 square feet at 8,300 to 9,000 BTU. That fits a one- or two-car garage, a cabin room or a workshop bay, not a whole house.

Is it safe to use indoors?

It is a wick-based kerosene heater with a safety grill and spill-resistant base. Kerosene heaters give off fumes and need ventilation, and should be kept away from children, pets and anything flammable.

What comes in the box?

The heater, a flame controller, fuel gauge, safety grill, siphon pump, funnel and a spare wick. You supply the kerosene.

How does it compare with a propane or electric heater?

It needs no power and costs less to run than many electric space heaters, but it adds odor and moisture and gives no thermostat control. Propane heats faster but needs cylinders and venting.

Our take on the Koolee 9000 BTU Portable Kerosene Convection Heater

The Koolee is a freestanding kerosene convection heater rated at 8,300 to 9,000 BTU, enough to warm roughly 140 to 160 square feet. It runs on a 4.3L tank with no electricity, burning 0.23 to 0.26 L/h for up to 16 hours of continuous heat. A flame controller, fuel gauge, safety grill and spill-resistant base are built in, and a top grate lets you keep food or a kettle warm. It suits garages, cabins, workshops and outage backup where there is no outlet, and it competes with other wick-style kerosene heaters on runtime and the included siphon pump, funnel and spare wick rather than on thermostats or fans.
