(Camp Addict does NOT accept payment from any company to review or endorse their products.)
Whether you are camping in the cold or looking for a portable heater to provide warmth in your garage, there is a portable propane heater that's right for you.
Below we review portable indoor propane heaters that are suitable for use inside RVs or most any other enclosed space that needs some heat.
Portable Propane Heater Reviews
Great as an RV furnace is, there can be many times when it is more economical or just smarter to use some type of portable heater for RVs.
All but one (golf cart heater) of the portable camper heaters we review here are safe for indoor use.
This means that you can also use them in your workshop, bedroom, greenhouse, etc if you want to when you're not RVing.
Below you will find what we feel are the best options for a portable camper heater.
We include a couple of indoor propane heater reviews, a nifty compact electric heater for those of you who often have shore power, as well as a propane golf cart heater for those of you who tool around in one.
All but the golf cart heater are safe for indoor use (just follow the directions!).
If Not Used Properly, You Can Die
ALWAYS, ALWAYS, ALWAYS follow the manufacturer's instructions when using an indoor propane heater.
Failure to do so can result in DEATH!
DEATH, people. Used with proper ventilation, and a healthy dose of common sense, they are safe.

Best Portable Propane Heater For High Elevations
Camco Olympian Wave Heater
The Camco Olympian Wave Heater performs better at higher elevations than the Mr. Heater Buddy Heater does.
If you spend a lot of time at altitude (above 7,000 feet), this is the propane RV heater you should take a hard look at.
Best Portable RV Electric Heater
There are many choices when it comes to electric RV heaters.
We like the pureHeat SNUG electric heater since it won't sacrifice any floor or counter space.
It's well under 1200 Watts, making it safe to use in your RV.

Portable Propane Heater Purchase Considerations
In addition to what you can learn by reading our Indoor Propane Heater Guide, below are a few things to consider when it comes time to purchase your portable propane heater.
How Long Will A Buddy Heater Run?
Do you want to know how long a Big Buddy Heater will run on a 20-lb tank?
Or how long a Little Buddy Heater will run on a 1-pound propane canister?
Or for that matter, you may wonder long any of the Buddy Heaters will run on a given supply of propane before you have to worry about your fingers and toes becoming numb.
How long a Buddy Heater will run depends on two things - supply (of propane) and demand (how long you have it on).
Can we get a 'duh!'?
Oh, you wanted specifics?
Not satisfied with that really vague answer?
The below chart is based on data published in the various Buddy Heater owner's manuals and the Mr. Heater website.
Don't take these run times as gospel.
They are only an approximate range.
If your Mr. Heater Big Buddy run time doesn't match the times listed below, then that's just how life goes.
It will pay to have way more fuel on hand than you think will be necessary, if you are in deadly cold temperatures.
In other words, your mileage may (and most likely will) vary.
The Cold Air Effect
Run times can be significantly reduced in temperatures below 20º F.
(In other words, you are using an external tank that is in below 20ºF temperature air.
(This won't apply if the outside temps are below 20º but your 1-lb propane cylinder is inside in relative warmth.)
The reduced run time at low temperatures has to do with LP gas properties when the gas is cooled below a certain point.
Buddy Heater Model
Big Buddy (MH18B)
One 1-lb Cylinder
1.5 to 6 hours
Two 1-lb Cylinders
3 to 12 hours
25 to 110 hours
Portable Buddy (MH9BX)
2.4 to 5.4 hours
48 to 110 hours
Hunting Buddy (MH12HB)
1.5 to 3.5 hours
36 to 72 hours
Little Buddy (MH4B)
* Depends on heat setting. If there are multiple heat settings for a particular Buddy Heater model, then the run time will be expressed in a range with the shortest time being the highest heat setting and the longest time being the lowest heat setting.
How Many BTU's Do I Need?
Below is a way to quickly approximate the amount of BTU's (heater heat output) you will need for your space.
You can use this with the manufacturers recommended maximum square footage to figure out what size heater you should purchase.
Warning- Math! Haha.
You can calculate the amount of BTUs required by using the following method:
- Measure the space’s dimension to determine cubic feet: Length x Width x Height = Cubic Feet
- Subtract the outside temperature from the desired inside temp to determine the temperature increase (either in Fahrenheit or Celsius).
- Calculate the approximate BTU requirements using either the Fahrenheit or Celsius formula below:
Fahrenheit Calculation: Cubic Feet x Temperature Increase (in Fahrenheit) x .133 = Required BTUs
Celsius Calculation: Cubic Feet x Temperature Increase (in Celsius) x .2394 = Required BTUs
Again, this is just an estimate.
The construction quality of the area you are trying to heat will play a large factor in how many BTUs you need.
A cheaply built RV with zero insulation will require a larger heater than a quality rig actually built for cold weather.
Refill 1-Pound Propane Cylinders Legally
The Buddy Heater line of portable propane heaters can run off the small (normally green in color) 1-pound propane bottles.
You know, the kind that are a few bucks at the local store and you toss when you're done.
Because they cannot be refilled.
Yep, they normally are not supposed to be refilled and then traveled with.
Yes, we know people do it all the time. People do a lot of stuff all the time that isn't 'right'.
**Insert eye-roll here**
There is actually a legal way to safety refill 1-lb propane cylinders.
The Flame King 1-lb Refillable Cylinder Refill Kit comes with a stand, a refill adapter, and a single refillable 1-lb propane bottle (you can purchase additional ones).
If you want to save money in the long run by not purchasing relatively expensive disposable 1-pound propane cylinders, consider the Flame King refill kit.
Legally Refill 1-Pound Propane Bottles
Most RVs come with some type of pre-installed heating system.
Even so, one may need a supplemental heater to use either in place of the installed system or to use as a supplement during certain called for situations.
Having a secondary heating method can mean the difference between life and death.
We highly recommend having a supplemental portable propane heater of some kind to have on hand while camping in or living in an RV.
It's always prudent to make sure you are safe and cozy when camping.
Having a supplemental heating system for your RV is a no-brainer for safety and comfort.
Get out there and Camp On!
He-llllo. I'm the co-founder of Camp Addict, which my biz partner and I launched in 2017. I frigging love the RVing lifestyle but in December of 2020, I converted to part-time RV life. Heck, I lived in my travel trailer for over 5.5 years, STRICTLY boondocking for pretty much all of it. Boondocking is a GREAT way to live, but it's not easy. Anyway, I'm passionate about animals, can't stand campgrounds, I hardly ever cook, and I love a good dance party. Currently, I can be found plotting and scheming whether or not to start collecting farm animals (or plotting my next RV trip!) at my beautiful new 'ranch' named 'Hotel Kellyfornia', in Southern Arizona.
Camp Addict co-founder Marshall Wendler brings his technical expertise to help explain RV products in an easy to understand fashion. Full-time RVing from April 2014 - December 2020 (now RVing about 50% of the time), Marshall loves sharing his knowledge of the RV lifestyle. Marshall spends the majority of his RVing life boondocking. He is the part of Camp Addict that knows 'all the things'. He's good at sharing his technical knowledge so you can benefit.
