Find In StoreThe Mr. Heater Portable Buddy is North America's most popular portable propane heater — and it's earned that title by being the right size, the right output, and the right price for anyone who needs reliable heat away from a power source. A patented radiant 4,000 to 9,000 BTU output connects directly to a standard 1 lb. propane cylinder and heats enclosed spaces up to 225 square feet for up to 5.4 hours on high. The expertly engineered size-to-BTU ratio keeps the footprint compact without sacrificing heat output, and the fold-down handle makes it easy to carry to a hunting blind, ice shack, job trailer, tent, or anywhere else you need warmth on demand. The swivel regulator gives you the flexibility to run off a disposable 1 lb. cylinder or connect to a remote 20 lb. tank with an optional hose and filter, extending runtime significantly for longer outings.
Features
- 4,000 to 9,000 BTU radiant propane heat output with two heat settings — low for extended runtime and high for maximum heat in larger or colder spaces.
- Heats enclosed spaces up to 225 sq. ft. — ideal for large tents, hunting blinds, ice fishing shacks, job site trailers, and other small to medium enclosed spaces.
- Oxygen Depletion Sensor automatically shuts the heater off when oxygen levels in the space drop below a safe threshold, providing essential protection in enclosed environments.
- Accidental tip-over safety shut-off automatically cuts fuel flow if the unit is knocked over, preventing fire or fuel release hazards.
- Piezo push-button ignition lights the unit without batteries or an external ignition source — simply rotate the knob to pilot and push.
- Swivel regulator adapts the heater from a 1 lb. disposable propane cylinder to a remote 20 lb. tank supply with the purchase of an optional hose and filter, significantly extending runtime.
- Fold-down handle reduces the heater's footprint for compact storage and provides a comfortable carry grip when moving between locations.
- Single-control knob design simplifies operation — rotate to pilot, push to ignite, then rotate to desired heat setting.
- Includes Piezo igniter built into the unit.
- Compatible with optional 1 lb. x 4 ft. hose and filter assembly for remote tank connection (sold separately).
