Our Verdict

This bundle gives you a proven propane heater plus all the gear to start heating right away. The carry bag, 10-foot hose, and refill adapter are all included.

It puts out up to 9,000 BTU per hour. That heats about 225 square feet. Most electric space heaters top out at 5,120 BTU.

Two built-in safety systems protect you. The Oxygen Depletion Sensor shuts off the unit if oxygen drops too low. The tip-over switch cuts fuel if the heater falls.

You get no thermostat or timer. You must switch between two heat settings manually. This takes more attention than most electric heaters require.

This heater runs on propane, not electricity. That makes it ideal for garages, workshops, and power outages. You can use it anywhere without an outlet.

Standout Features

Oxygen Depletion Sensor (ODS)

This safety feature is rare in portable heaters. Most electric space heaters lack ODS entirely. It automatically shuts off the unit when oxygen drops to an unsafe level.

9,000 BTU heat output

This equals about 2,638 watts of heat. The typical electric space heater produces 1,500 watts (5,120 BTU). This unit delivers nearly double that heat output.

4-item complete bundle

Most heaters sell the carry bag, hose, and adapter as separate purchases. This bundle includes all four items together at the listed price.
