The Mr. Heater Corporation MH18B is a highly portable indoor propane heater. It has a heating output of 18,000 BTU and can heat up spaces of up to 450 sq ft. It has three heating adjustments; low, medium and high. You can toggle through these modes manually or leave it up to the heater to choose, based on the temperature you have set it to achieve.

This unit has a commendable array of safety functions. It features an oxygen depletion sensor(ODS)  that shuts it off when it detects low oxygen levels in your home. Another safety feature is the tip-over shut-off. This system detects when the heater tilts or tips over and turns it off to prevent unfortunate accidents. 

Average indoor propane heaters feature a pilot light. The Mr. Heater MH18B, however, comes with electronic ignition. To light it, simply push the knob and rotate it to regulate the flame. For more convenience, the heater also features two swivel regulators. You can therefore attach a hose connected to an external gas supply if the onboard propane tank is empty. 

All in all, the MH18B is an excellent indoor propane heater. It delivers outstanding heating performance in a body that is light and easy to move. Admittedly, it burns through propane quicker than some competitors. Nevertheless, its ability to support external gas sources can offer some much needed reprieve when the tank runs dry.

  • Ultra-sensitive ODS and tip-over safety features
  • High heat output
  • Dual swivel regulators


  • Goes through a lot of propane.

The Mr. Heater Corporation F299730 differs from its counterpart, the Mr. Heater MH18B in almost every way. For starters, while the MH18B’s design emphasizes portability, the F299730 is best deployed semi-permanently on a wall or floor. With a heat output of 30,000 BTU, it also heats up a larger area of 750 square feet.

Most users recommend using the F299730 as a supplement for central heating. You can deploy it in rooms that do not warm up well, so that you can adjust their temperature level without affecting the rest of your home. The inbuilt thermostat enables the unit to maintain the temperature you set autonomously. 

As you would expect for a mounted heater, the Mr. Heater F299730 does not feature a host of safety functions. Furthermore, the fan is rather underpowered. Nevertheless, it is still an excellent choice for affordable living-space heating.
