Mr. Heater F232000 MH9BX

The portable radiant Mr. Heater F232000 MH9BX will be your best friend when you are trying to heat smaller areas, outside or inside. It is perfect for camping, ice fishing shanties, garages and more. Just hook it up to a 1 lb or even a 20 lb propane cylinder with the optional hose connection. This little guy may look small, but it sends out a massive amount of heat.

Review Details

Mr. Heater F232000 is perfect for that camping trip in the woods or that ice fishing trip on the lake. Ice fishing can take up some time and Mr.Heater is great with time, it provides 3 to 6 hours of heat with the small 1 lb propane tank and 48 hours with the 20 lb tank. There will be no more bundling up under the covers to stay warm while you are camping.

It is also safe for indoor use which is perfect for if the power goes out and you have no heat. Mr.Heater is definitely a heater that beats the rest when it comes to size, cost, and safety.

What We Liked

  • Fold down handle
    Handles can make for unfitting storage, but with Mr. Heater you can just fold down the handle and store it almost anywhere, without having to store around the handle itself.
  • Durable porcelain coated reflector
    If you accidentally drop this heater, the durable porcelain reflector will help guard the heating surface from damage.
  • Low-oxygen safety shut-off(ODS)
    When the oxygen content in the room drops to 18% from the normal 21%+, the heater will automatically shut off.
  • Tip-over safety shut off
    If Mr.Heater gets knocked over on accident, it will shut off. Older heaters will stay running, which can cause a fire.
  • Large heating surface
    This is great for heating larger areas. Mr.Heater heats up to 200 square feet.
  • Swivel out fuel connection
    If you are putting the heater in a small space, the swivel makes it easy to just plug in the propane and go.

What We Didn't Like

  • Large propane tank
    A 20 lb propane isn't the easiest thing to carry around, especially in the house when moving from room to room.
  • 6 volt wall power supply is not included.
    In order to run the fan, you either need D-cell batteries or the wall power supply and batteries can start to get expensive.


The Mr. Heater 4,000-9,000-BTU Buddy has proven to be safe and effective. It does have it's flaws, but it is nothing that cannot be simply fixed. The price is right for a heater that does so much with so little effort. It is definitely a great choice if you need a little extra heat in your garage, tent or whatever area that needs heat.
