The Mr. Heater 3,800 BTU Portable Little Buddy Heater gives ice anglers a compact heat source for cold mornings in an ice fishing shanty, shelter, hunting blind, workshop, or other small space. Producing 3,800 BTU per hour, this portable propane heater warms areas up to 95 sq. ft. and runs for up to 5.6 hours from a single 1 lb. disposable propane cylinder (propane not included). Its 8 in. round stand keeps the footprint small around buckets, tackle, electronics, and other gear, while one-button Piezo ignition makes startup simple. Quiet, clean, odor-free operation helps keep the focus on jigging for walleye, perch, crappie, trout, and other cold-water species. An Oxygen Depletion Sensor and accidental tip-over shutoff add important safeguards during use.3,800 BTU output heats up to 95 sq. ft.Runs up to 5.6 hours per 1 lb. propane cylinder (not included)One-button Piezo ignition for quick startupCompact 8 in. round stand saves floor spaceAutomatic accidental tip-over and low oxygen safety shut-offManufacturer's one-year limited warranty
