Mr. Heater F232000 MH9BX Buddy 4,000-9,000-BTU Indoor-Safe Portable Propane Radiant Heater, Red-BlackOxygen depletion system: The ODS is a feature built into the Big Buddy. Propane heaters often suck the oxygen out of the air. Thus, it is important to use an oxygen sensor in order to detect whether there is enough oxygen to go around. If oxygen depletion is occurring, the Big Buddy Heater will detect this and automatically shut itself off. However, due to this oxygen depletion system, it is not wise to use the Big Buddy Heater over 7,000 feet since oxygen ratings will vary.

Built-in blower fan: In order to allow the heat to dissipate, the Big Buddy Heater uses a built-in blower fan that runs on either 4 D cell batteries or an electrical outlet using a power adapter. Heat flows from two different compartments. The middle compartment blows heat sideways while the top compartment blows it above.

Tip over safety shut-off: In case the Big Buddy Heater tips over, there’s a safety shut-off feature that will prevent any fire hazards.

Heats 400 square feet: The Big Buddy Heater heats up to a 400 square foot room. This is four times the area of the Little Buddy Heater, which heats 100 square feet.

Pros

  • Safe to use indoors
  • Works very well even without the built-in fan.
  • On the highest temperature setting, the Big Buddy can heat up a small cabin in about 10 minutes.
  • Does not produce any fumes.

Cons

  • May produce a bit of moisture when indoors. This can be circumvented by cracking a window open.
  • Since the Big Buddy Heater produces a lot of heat, it may be too hot to put on a wooden floor. Please use a concrete or brick surface.
  • Any gentle bump of the heater will cause it to shut off. However, this is just a safety feature so it could be more of a pro.

The Verdict

The Big Buddy Heater is the biggest heater out of the entire Mr. Heater line. It is able to heat up a 400 square foot room in less than 10 minutes. However, it also weighs the most at 20 pounds, while the Little Buddy Heater weighs in at only 5 pounds.

The Big Buddy Heater comes in handy if you are going to be leaving this in a room or in a spot outside for longer periods of time. It would start getting a bit heavy if you were to lug it around everywhere you go. In contrast, the Portable Buddy Heater only weighs 9.5 pounds, but can only heat up a 200 square foot room.

In our opinion, it is best to go with a heater that is as small as you can get for the amount of space that you want to heat.

Overall however, the Big Buddy Heater has excellent reviews. It is one of the best interior and outdoor heaters available today, as with the rest of the Mr. Heater line.
