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.

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?
Read on...
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 | Propane Source | Run Time* |
---|---|---|
Big Buddy (MH18B) | One 1-lb Cylinder | 1.5 to 6 hours |
Two 1-lb Cylinders | 3 to 12 hours | |
20-lb Tank | 25 to 110 hours | |
Portable Buddy (MH9BX) | 1-lb Cylinder | 2.4 to 5.4 hours |
20-lb Tank | 48 to 110 hours | |
Hunting Buddy (MH12HB) | 1-lb Cylinder | 1.5 to 3.5 hours |
20-lb Tank | 36 to 72 hours | |
Little Buddy (MH4B) | 1-lb Cylinder | 5 hours |
* 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**
Flame King Refillable Propane Cylinder Kit
Refill Kit
Fear not!
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).
Extra Cylinder
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
Conclusion
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.

Why list electric heaters on a “indoor propane heater” page?
Why list outdoor-only models?
Why have “select a color” button that doesn’t do anything?
All legit questions- thank you for asking! Here are our answers:
1. The page was intended to be for alternative heaters from built-in RV heaters, as we alluded to in the intro of the page. Any kind of portable heater. So yes, there’s also a portable electric heater in there. Just gave an alternative for when one doesn’t want to run propane, as we don’t have a page on ‘indoor RV electric heaters’.
2. The only outdoor model we listed is the golf cart Buddy. Common sense says it should be used in a golf cart and not indoors. Still, it’s relevant to RVing as many RVers bring golf carts with them so we included it. Otherwise, maybe you are speaking of the Buddy Heaters for Canada/Massachussetts. We only point out that if you try to buy a Buddy heater made in Massachusetts or Canada, it WILL be rated as ‘outdoor only’, simply due to legislation of the rules for indoor propane heaters in those places. They are the same product. But to be LEGAL about it, you would have to get the ones we list for those areas to use them indoors legally.
3. There are no ‘select a color’ buttons. (Buddy Heater section) It’s just text. It’s there to let you that you will need to choose your color when you get to Amazon. However, upon re-review of two of the Buddy heaters on that page, there were no longer any colors to choose from. We have removed ‘select color’ from those product links.
That’s it, we hope we answered your questions sufficiently and that you found some assistance from this page about portable RV heaters, propane or otherwise!
