  • Our take on the Mr. Heater Big Buddy Portable Heater

    The Big Buddy is a radiant propane heater that runs on two 1 lb cylinders and puts out 4,000, 9,000 or 18,000 Btu. It is built for enclosed spaces such as cabins, garages and job sites up to about 450 sq ft. Two swivel regulators let you switch to a remote tank with a hose and filter, and a Piezo igniter, oxygen depletion sensor and tip-over shut-off are standard. It is the best-known heater in its class; rivals like the smaller Buddy and Little Buddy trade output for portability, and the Big Buddy's higher heat comes with faster fuel burn.

    What reviewers say

    Owners rate the Big Buddy highly for fast, strong heat in cold cabins and garages and for its simple push-and-turn lighting. The main complaints are fuel consumption on 1 lb cylinders and the bulk of the unit.

    What people mention
    • Heat outputPraisedOwners say it warms a cold cabin or garage fast on the high setting.
    • Fuel useCriticisedReviewers note that 1 lb cylinders drain quickly at full output, so many switch to a bulk tank.
    • PortabilityCriticisedThe unit is heavy and bulky to carry compared with the smaller Buddy heaters.
    • IgnitionPraisedThe push-and-turn Piezo ignition is described as reliable and easy.
    • SafetyPraisedBuyers value the oxygen depletion sensor and tip-over shut-off for indoor use.

    About the Mr. Heater Big Buddy Portable Heater

    The Big Buddy is a portable radiant propane heater with an output of 4,000 to 18,000 Btu. It connects directly to two 1 lb propane cylinders. It is designed to heat enclosed spaces such as cabins, up to 450 sq ft.

    Two swivel regulators let you use disposable cylinders or a remote gas supply. Switching to a remote supply requires buying a single hose and filter. To light the heater, push in and rotate the knob. The built-in Piezo sparking mechanism does the rest.

    An oxygen depletion sensor (ODS) and an accidental tip-over safety shut-off are built in for indoor use.

    Questions and answers

    How much space can the Big Buddy heat?
    Mr. Heater rates it for enclosed spaces up to about 450 sq ft. Real-world results depend on insulation, outside temperature and how close you are to the radiant face.
    Can I connect it to a 20 lb propane tank?
    Yes. The two swivel regulators accept a hose and filter, which you buy separately, so you can run it from a remote gas supply instead of 1 lb cylinders.
    How long does a 1 lb cylinder last?
    Expect only a few hours per cylinder on the high setting and much longer on low. For regular use, a bulk tank is far more economical.
    Is it safe to use indoors?
    It has an oxygen depletion sensor and a tip-over shut-off, and Mr. Heater lists it for indoor use in enclosed spaces. Propane heaters still need some ventilation and should never be used in a tent or vehicle while sleeping.
    What is the difference from the smaller Buddy heater?
    The Big Buddy adds a third setting and higher maximum output, plus dual swivel regulators for a bulk tank. The smaller Buddy is lighter and easier to carry but heats less space.
    Does it need electricity?
    No. Ignition is a Piezo spark and the heater runs on propane alone, so it works during a power outage.
    Where is the Mr. Heater Big Buddy Portable Heater cheapest?
    At Shell Lumber and Hardware, for $169.96, as of our latest check.
