Mr. Heater F232000 MH9BX Buddy Heater Review
The Mr. Heater F232000 MH9BX Buddy is the model most people picture when they think of a portable propane radiant heater, and the reason is its combination of small size and indoor certification. This review works from the published specification and the listed safety approvals rather than any hands-off trial.
Design and Setup: There is no assembly. The unit takes a 1-pound propane cylinder directly, or a bulk tank through a hose and filter, and lights from a knob with a piezo igniter. The size is the selling point: it carries like a grocery bag by its fold-down handle, yet is rated to warm a tent or a small room.
Safety: This is the part that separates the Buddy from generic propane heaters. It carries an oxygen depletion sensor (ODS) that cuts the gas if oxygen in the room falls, plus a tip-over switch that shuts it down if knocked over. Those two features are why it is sold as indoor-safe, and neither removes the need for a cracked window or vent. It should never be run in a sealed space or left burning overnight.
Competitors Comparison: Shoppers usually cross-shop this against Dyna-Glo and Texsport units. Mr. Heater leads on portability and the ODS safety package. Where it gives ground is BTU output against larger cabinet and wall models: at 4,000 to 9,000 BTUs it is built for a tent, a truck cab, or a single small room, not a workshop. Anyone heating a bigger area should step up to the Mr. Heater F274800 Big Buddy, while hunters and ice anglers often prefer the MH12HB Hunting Buddy. For a fixed installation rather than a portable, a vent-free unit such as the Dyna-Glo RMC-LPC200DG covers more square footage.
Cost Analysis: At $80-$100, it sits mid-pack on price. The running cost depends entirely on propane: 1-pound cylinders are convenient but expensive per BTU, and connecting a 20-pound tank through the accessory hose lowers the cost substantially for anyone using it regularly. Compared with running electric resistance heat in an uninsulated garage or a tent, propane is usually the cheaper source of heat. The wider propane space heater category covers the larger formats.
Pros & Cons

- Indoor-Rated Design: Approved for indoor use when the room is ventilated, thanks to the oxygen depletion sensor.

Cons:
- Limited BTU Range: Suitable for smaller spaces but might struggle in larger areas.
