Product Overview

The Mr. Heater F232000 MH9BX Portable Heater is a radiant propane model that needs clean-burning propane to function. It is suitable for an area that measures of up to 225 sq. ft. and has been cleared for indoor and outdoor use, making it a versatile option. The tank holds 1 gallon of propane at a time and is capable for producing heat for 3 hours. This comes out to a fuel consumption/burn rate of 4000 BTU = 0.044 Gal/Hr., at 9000 BTU = 0.099 Gal/Hr.

This propane fireplace heater is constructed of steel, plastic, and nickel so it is lightweight but still durable enough to survive being moved around. It is an all around inexpensive model and has some significant features. One of the most important is the auto shut off, which kicks in if something knocks the heater over. This prevents fire and makes it safe to bring the heater in places like barns where animals might bump into it. The auto shut off also kicks in when there are low oxygen levels or if the pilot light goes out.

Some final features of note are the fold down handle and swivel regulator, which contribute to the portability of the Mr. Heater Ff232000 MH9BX Portable Heater.

The importance of portable heaters

Humans operate best when their bodies are kept at an optimal temperature. For most people, this temperature tends to be around 70 degrees Fahrenheit with some variations. It can be difficult, though, to keep the ambient environment comfortable, especially if you need to work outdoors or live somewhere with high energy costs.

Portable heaters are essential for a variety of situations:

● Power outages
● Blizzards
● Working out in fields
● Camping
● Hiking
● Saving on energy bills

Staying warm is essential for human survival, so portable heaters are crucial, especially for those who live in naturally cold regions. Plus people work better when they are comfortable, so workers who need to constantly be outside – farmers and construction workers come to mind – often benefit from having an ambient, portable heater to stay warm.

Radiant Heater Information

This Mr. Heater F232000 MH9BX is a radiant model, which means the heat it produces is transferred directly to objects. Instead of blowing hot air, radiant heaters produce infrared wavelengths that warm up surfaces, making them an excellent option for areas with poor insulation where other types of heating are impossible.

Radiant heaters are easy to set up and work in almost every environment. While they can be expensive, the Mr. Heater F232000 MH9BX is surprisingly affordable, making it a great choice for someone who wants to save on energy bills or who just needs a little extra warmth while working outdoors, in the garage, or in a barn. Plus, there is a low fire risk.

Pros and Cons


● Portable – This heater actually makes good on its promise to be portable since it has a convenient handle for carrying and only weighs 9 lbs
● Efficient – A single gallon of propane is enough for 3 hours of heat in a 225 sq. ft. area
● Clean Burning – Like it says, this heater doesn’t produce any unpleasant smoke when running
● Warranty – A reliable 2 year warranty is included with purchase
● Safety – This heater has a reliable auto shut off feature that goes off in the heater accidentally gets knocked over or detects an issue with the product’s mechanisms


● Customer Service – While this is a great product, the company that manufactures the Mr. Heater is awful about responding to emails with questions and queries
● Control Knob – Sometimes the control knob gets stuck and needs to be jiggled loose to turn the heater off


Not everyone needs a portable heater, but they are a great possession to have for all of those terrifying “What if” scenarios, like should the power go out or the energy bill simply becomes too expensive. For someone who prefers radiant heat and has no problem with propane, the Mr. Heater F232000 MH9BX Portable Heater is a great option.
