What to know before buying

Listing details to confirm

Output information is contradictory: the title and heat-setting description claim up to 18,000 BTU, while the specification lists 15000 british thermal units. The 4,000/9,000/18,000 BTU settings, coverage up to 450 sq. ft., and 5–7-hour runtime are listing claims, not independently confirmed. The listing describes indoor use but does not provide operating instructions or conditions here, so check the manual and applicable requirements before indoor use.

Frequently asked questions

What heat output does the DECOKTOOL B3672 provide?

The listing gives conflicting output information. The title and setting descriptions reach 18,000 BTU, but the specification table lists 15000 british thermal units. Confirm the applicable rating before buying.

What heat settings are described?

The listing describes three settings: 4,000 BTU, 9,000 BTU, and 18,000 BTU. These are manufacturer claims and conflict with the separate listed output value.

Is a propane cylinder included?

The listing says the heater is compatible with standard 1 lb propane cylinders and explicitly says the propane tank is not included.

What safety features are listed?

The listing describes an ODS, tip-over safety switch, flame-out protection and a protective front grille. These are listing claims, not independently verified safety guarantees.
