Our take on the Mr. Heater Portable Buddy Heater MH9BX 4,000-9,000 BTU Indoor-Safe Propane Radiant Heater

The Mr. Heater Portable Buddy MH9BX is a propane radiant heater that runs on a 1 lb cylinder and puts out 4,000 or 9,000 BTU, enough for a tent, garage, ice-fishing shelter or small room up to about 225 sq ft. It heats people and objects directly with an infrared panel rather than blowing warm air, and it lights with a push-button Piezo igniter, no matches or batteries. A tip-over switch and an oxygen-depletion sensor shut it down, and the fold-down handle and swivel regulator make it easy to carry and hook up. Against catalytic and fan-forced portable heaters it is simpler and quieter, but it gives off combustion moisture and needs ventilation, and owners report the shut-off sensor can be fussy in cold or windy spots.

What reviewers say

Owners treat the Buddy as a dependable small-space heater that starts easily and throws serious heat for its size. Complaints center on short run time on 1 lb cylinders, moisture indoors, and a tip-over switch that sometimes shuts the unit off on rough ground.

Questions and answers

Is the Buddy heater safe to use indoors?
Mr. Heater rates it for indoor use with ventilation, and it has an oxygen-depletion sensor plus a tip-over shut-off. It still burns propane and adds moisture, so crack a window or vent a tent.
How long does a 1 lb propane cylinder last?
About 6 hours on the 4,000 BTU low setting and about 3 hours on 9,000 BTU high. A 20 lb tank with the optional hose and filter runs far longer.
Can I connect it to a 20 lb tank?
Yes, with Mr. Heater's hose and filter accessory. The built-in swivel regulator fits a 1 lb cylinder directly.
Does it need batteries or electricity?
No. The Piezo igniter is mechanical and the heater runs entirely on propane, so it works in a power outage.
How much space will it heat?
Mr. Heater rates it for spaces up to about 225 sq ft. Radiant heat is directional, so it works best aimed at people rather than heating a whole room evenly.
What is the difference from the Big Buddy?
The Big Buddy adds a third burner and a fan, reaching higher BTU and larger spaces. The Portable Buddy is smaller, lighter and simpler for one or two people.
