About this product

Mr Heater 18,000 BTU Big Buddy Portable Propane Heater 12 ft Propane Hose Assembly Portable Buddy Fuel Filter & Big Buddy Accessory Bag Bundle

Stay warm and travel prepared with the Big Buddy Heater Essentials & Carry Bag Bundle. Designed for cold campsites, frozen lakes, and outdoor adventures, the Big Buddy Heater delivers adjustable heat up to 18,000 BTUs and warms areas up to 450 sq. ft. Swivel regulators allow easy setup with two 1 lb. propane cylinders or connection to a 20 lb. tank, while the built-in Life Safety System—including an oxygen depletion sensor, thermal shut-down, and tip-over switch—ensures safe indoor or outdoor operation. This bundle includes a 12 ft. propane hose with soft nose P.O.L. and 1"–20 throwaway fitting, plus a recommended fuel filter to protect the heater and extend its lifespan. Everything packs neatly into a durable 600D poly carry bag with padded strap, U-shaped zipper, and extra storage pockets—making transport and organization effortless wherever you go.

Hi Josh, this unit used to have a fan but Mr Heater has removed it due to tariff regulations.
