Mr Heater MH9BX Review – Winter is Coming!

The Mr Heater MH9BX is North America’s Most Popular Portable Propane Heater! I have owned one of these for a few years now and use it regularly. This Mr Heater portable propane heater is versatile as it can be used in a variety of scenarios such as tents, tailgates, hunting blinds, emergency heating, etc. You name it, you can use it. The Mr. Heater brand has been around since 1984, and produces some of the best heaters on the market. We’ll also look at a couple of Mr Heater accessories that’ll make your experience a little better.

Users Tip: The Mr. Heater heavy duty cover can also be used as a cooking surface!

Of course, there are other options for heating while outdoors. You could build a fire. Unfortunately, there are often times burn bans in certain areas during the drier months. You will also have to bring or locate firewood before you can start your fire. Once all that is completed and you’re off to bed for the evening, you still have to worry about heat. Having a portable, safe for indoor use heater will alleviate those issues and allow you to rest comfortably.

About the Mr. Heater MH9BX

This radiant 4,000-9,000 BTU Liquid Propane heater will connect directly to a 1 lb. cylinder. This is perfect solution for heating enclosed spaces up to 225 sq. ft. This heater is fitted with a fold down handle, giving maximum output while retaining a minimalist footprint. A swivel regulator gives you the ability to adapt usage from a disposable cylinder to a remote gas supply with the purchase of a hose and filter. To light, simply rotate the knob to pilot and push. The heater features a Piezo sparking mechanism making ignition a breeze. Safety features include the  Oxygen Depletion Sensor (ODS) and accidental tip-over safety shut-off providing many adventures with a safe and reliable heater.
