Our take on the MH9BX Buddy Portable Propane Radiant Heater

The Mr. Heater MH9BX Buddy is a portable radiant propane heater that runs on a 1 lb propane cylinder or, with an optional hose and filter, a 20 lb tank. It puts out 4,000 or 9,000 BTU and is rated for indoor use in enclosed spaces up to about 225 square feet. A tip-over shut-off, Piezo igniter and fold-down handle make it a common pick for tents, garages, job sites and ice fishing. Against catalytic and electric rivals it heats fast and needs no power, but it burns propane quickly at full output and puts out noticeable moisture and odor.

About the MH9BX Buddy Portable Propane Radiant Heater

Heater Buddy is a portable radiant heater that runs on propane. It connects directly to a 1-pound propane cylinder. With an optional hose and filter, it can connect to a 20-pound cylinder or other remote gas supply through its swivel regulator.

It heats enclosed spaces up to 225 square feet, including large tents up to 200 square feet. It has high and low heat settings. It is used for emergency heat, tents, campers, workshops, job sites, porches, decks, garages, barns, sheds, hunting blinds and ice fishing shanties.

To light it, turn the knob to pilot and push. The Piezo igniter then sparks the flame. An Oxygen Depletion Sensor and an accidental tip-over safety shut-off are built in. At altitudes over 7,000 feet above sea level, the heater may shut off.
