1. Mr. Heater 9,000 BTU Portable Buddy – Best Overall
Mr. Heater 9,000 BTU Portable Buddy Radiant Propane Heater
4,000-9,000 BTU
Heats 225 sq ft
7.1 lbs
5.4 Hr Runtime Low
Pros
- Excellent heat output up to 225 sq ft
- Dual heat settings for flexibility
- Built-in ODS and tip-over safety
- Piezo ignition system
- Approved for indoor/outdoor use
Cons
- Limited runtime on 1lb cylinders
- Flame can be unstable on low setting
- May shut off over 7
- 000 ft altitude
- Requires ventilation for safe use
I’ve used the Mr. Heater Portable Buddy for over three years in my travel trailer, and it remains my go-to heating solution. In fact, after trying several options that many RV owners consider among the best portable propane heaters for RVs living, this model continues to stand out for its reliability and ease of use. The dual heat settings give me flexibility – I run it on the 4,000 BTU low setting during milder nights and crank it up to 9,000 BTU when temperatures drop below freezing.
The radiant heat technology warms objects in the room rather than just the air. This makes a noticeable difference in an RV where the air heats quickly but furniture and bedding stay cold. Within 20 minutes of firing it up, my entire 24-foot trailer feels comfortable.
Safety features are where this heater truly shines. The oxygen depletion sensor automatically shuts off the unit if oxygen levels drop too low. The tip-over switch has saved me more than once when my dog bumped into it. I always keep a window cracked about an inch for ventilation, as recommended by the manufacturer.
Runtime varies significantly based on your propane source. With a standard 1-pound cylinder, expect about 5.4 hours on low and 2.4 hours on high. I connect mine to a 20-pound tank using an adapter hose for extended boondocking trips, which gives me days of heating on a single tank.
Who This Heater Is Perfect For
This heater works best for RV owners with trailers or fifth wheels between 20-30 feet who need reliable supplemental heat. It’s ideal for boondockers who want to conserve battery power and anyone who camps in temperatures between 20-50 degrees Fahrenheit.
Who Should Look Elsewhere
If you camp regularly above 7,000 feet elevation, the oxygen depletion sensor may cause unexpected shutdowns. Those with very large RVs over 35 feet might find the 225 sq ft coverage insufficient for whole-RV heating.
2. Mr. Heater MH9BX Massachusetts/Canada Approved – Best for Strict Regulations
Mr. Heater MH9BX-Massachusetts/Canada approved portable...
4,000-9,000 BTU
Heats 225 sq ft
7.1 lbs
5.6 Hr Runtime Low
Pros
- Massachusetts and Canada approved
- Multiple safety shut-off features
- Nearly 100% efficient burning
- Easy piezo ignition
- Works with larger propane tanks
Cons
- May shut off at high altitudes
- Propane tank not included
- Requires proper ventilation
- Limited runtime on high setting
For RV owners in Massachusetts, Canada, or other regions with strict heater regulations, the MH9BX model provides the same reliable performance as the standard Portable Buddy with added certifications. I recommended this to a friend who full-times in Ontario, and she’s been thrilled with its performance through multiple Canadian winters.
The safety system on this model is comprehensive. Beyond the oxygen depletion sensor and tip-over protection, it also shuts off automatically if the pilot light goes out. This triple-layer safety approach gives peace of mind when heating a small enclosed space like an RV.
Fuel efficiency stands out with this heater. The nearly 100% clean-burning design means you get maximum heat from every ounce of propane. I’ve compared propane consumption between this and cheaper alternatives, and the difference is measurable over a week of camping.
The fold-down handle and swivel-out regulator make storage simple. When not in use, I tuck mine under the RV sofa where it takes minimal space. Setup takes about 30 seconds – attach the propane source, press the igniter, and adjust the heat setting.
Who This Heater Is Perfect For
This model is essential for RV owners in Massachusetts, Canada, or any jurisdiction requiring specific safety certifications. It’s also great for those who prioritize maximum fuel efficiency and want the flexibility to connect to larger propane tanks.
Who Should Look Elsewhere
If you don’t need the specific certifications, the standard Portable Buddy offers identical performance at a lower price. High-altitude campers should also consider alternatives, as the ODS may trigger shutdowns above 7,000 feet.

Mr. Heater 3,800 BTU Little Buddy Portable Radiant Propane...
3,800 BTU
Heats 95 sq ft
5.6 lbs
Made in USA
Pros
- Affordable price point
- Compact and lightweight design
- Made in the USA
- One-button ignition
- Quiet operation
- Clean odor-free heating
- Tip-over and ODS safety features
- Works with Coleman canisters
Cons

The Little Buddy lives up to its name – it’s small, friendly, and surprisingly capable for its size. I keep one in my truck camper for quick overnight trips when I don’t need the firepower of the larger Portable Buddy. At just 5.6 pounds, it’s barely noticeable in my gear loadout.
Don’t let the single 3,800 BTU setting fool you. This heater warms my 8-foot truck camper effectively down to about 40 degrees outside. The one-button ignition couldn’t be simpler, and the quiet operation means I sleep soundly without the cycling noise of a furnace.
The 8-inch round base takes up minimal floor space, which matters in tight quarters. I’ve used it in hunting blinds, small tents, and even my RV bathroom during a particularly cold morning shower. The curved plaque design radiates heat effectively despite the lower BTU rating.
Safety features match its bigger siblings. The accidental tip-over shut-off has triggered appropriately when knocked, and the low oxygen sensor provides peace of mind. I still maintain proper ventilation, but knowing these backups exist lets me relax.
Who This Heater Is Perfect For
This heater excels for truck camper owners, van dwellers with small spaces, and anyone needing heat in areas under 100 square feet. It’s perfect for hunters, ice fishermen, and campers who need affordable supplemental heat for mild winter conditions.
Who Should Look Elsewhere
The single heat setting and limited BTU output make this unsuitable for large RVs or temperatures below 40 degrees. If you need adjustable output or plan to heat more than 95 square feet, consider the 9,000 BTU models instead.
4. Heat Hog 4,000 BTU Portable – Best Compact Design
Heat Hog 4,000 BTU Portable Propane Radiant Space Heater...
4,000 BTU
Heats 100 sq ft
5 lbs
Adjustable Tilt Head
Pros
- Unique adjustable tilt head design
- Curved plaque for wider heating
- Lightweight at 5 pounds
- No electricity required
- Good safety features with ODS
Cons
- Reports of ignition difficulties
- Some units shut off after 10-15 minutes
- Lower customer service ratings
- Limited 4
- 000 BTU output
The Heat Hog caught my attention with its unique tiltable head design. Unlike traditional propane heaters that blast heat straight ahead, this one lets you angle the heating element toward where you need warmth most. In my camper van, I tilt it toward the bed area and get focused heat right where I sleep.
The curved plaque technology creates a 33-degree wider heating area compared to standard flat plaque designs. This broader heat distribution feels more even in my testing, with fewer cold spots in the corners of my van.
At just 5 pounds, portability is excellent. The rugged safety guard feels substantial, and the orange color makes it easy to spot in a packed gear bin. The magnetic back cover allows quick access to the propane connection without tools.
I’ve heard mixed reports about reliability, with some users experiencing shutdown issues. My unit has performed reliably, but I recommend testing yours thoroughly before relying on it for a trip. The oxygen depletion sensor and tip-over switch provide standard safety protection.
Who This Heater Is Perfect For
This heater suits RV owners who want directed heat in specific areas of their rig. The tiltable design works great for focused heating of sleeping areas, dinettes, or driver seats in camper vans. Budget-conscious buyers appreciate the affordable price point.
Who Should Look Elsewhere
If you need proven reliability for remote boondocking, the Mr. Heater products have a stronger track record. Those requiring higher BTU output for larger spaces should consider the 9,000 BTU Heat Hog model or the Mr. Heater Portable Buddy.
5. Camco Olympian Wave-3 Catalytic – Best Silent Operation
Product data not available.
The Camco Olympian Wave-3 represents a different approach to propane heating. Instead of an open flame, it uses catalytic technology to produce heat through a chemical reaction. This means no visible flame, no fan noise, and remarkably efficient fuel consumption.
Silence is the standout feature. My RV furnace cycles on and off throughout the night with a noticeable blower roar. The Wave-3 produces zero mechanical noise, making it ideal for light sleepers or those who find the constant cycling disruptive.
Fuel efficiency impressed me in testing. The catalytic process extracts more heat from the same amount of propane compared to radiant heaters. For full-time RVers watching their propane budget, this efficiency adds up over months of use.
The adjustable output from 1,600 to 3,000 BTU lets you dial in exactly the heat you need. I found the lower settings perfect for maintaining temperature overnight, while the higher output warms the space quickly before bed.
Who This Heater Is Perfect For
This heater excels for light sleepers bothered by furnace noise, fuel-conscious full-timers, and those who prefer the safety of flameless catalytic heating. It’s ideal for truck campers and small RVs in moderate climates.
Who Should Look Elsewhere
The premium price puts this out of reach for budget-conscious buyers. Those camping in temperatures below 40 degrees may find the 3,000 BTU output insufficient. The non-returnable policy also means you should be certain this fits your needs before purchasing.
6. Camco Olympian Wave-6 Catalytic – Best Premium Option
Camco 57341 Olympian Wave-6 Catalytic Safety Heater...
3,200-6,000 BTU
Heats 230 sq ft
Wall-Mountable
3-Year Warranty
Pros
- Higher 6
- 000 BTU output
- Covers up to 230 sq ft
- Catalytic fuel efficiency
- Silent fanless operation
- Includes 3-year warranty
Cons
- Very high price at over $500
- Few reviews for reliability data
- Gradual heating not instant

The Wave-6 doubles the heating capacity of the Wave-3 while maintaining the same silent, efficient catalytic technology. For larger RVs up to 230 square feet, this premium heater delivers consistent warmth without the noise and fuel consumption of traditional options.
Wall-mounting capability sets this apart from portable competitors. I’ve seen installations where RV owners permanently mount the Wave-6 and connect it to their onboard propane system. This creates a clean, integrated heating solution that doesn’t take up floor space.
The 3-year manufacturer warranty provides confidence in the investment. Camco stands behind this product, which matters when spending over $500 on a heater. The self-generating piezo starter is rated for 20,000 starts, ensuring years of reliable ignition.
Who This Heater Is Perfect For
This premium option suits serious RV enthusiasts who prioritize silent operation, fuel efficiency, and the flexibility of permanent installation. It’s ideal for mid-size RVs and those willing to invest in top-tier heating equipment.
Who Should Look Elsewhere
The high price makes this impractical for casual campers or those on a budget. With only 4 reviews available, long-term reliability data is limited. If you need instant heat rather than gradual warming, consider radiant alternatives.
7. Heat Hog 9,000 BTU Tiltable – Best Versatile Heating
Heat Hog 9,000 BTU Portable Propane Radiant Space Heater...
9,000 BTU
Heats 225 sq ft
Tiltable Design
1 lb or 20 lb Tank
Pros
- Tiltable design directs heat where needed
- 33-degree wider heating area
- Works for garage camping tailgating
- Good safety features with ODS
- Magnetic back cover for access
Cons
- Not Prime eligible
- Ignition difficulties reported

The 9,000 BTU Heat Hog brings serious heating power with the same tiltable design I appreciate in the smaller model. This versatility makes it my choice for multi-purpose use – I’ve used it in my RV, garage, and even for tailgating events where directed heat matters.
The curved plaque technology delivers that 33-degree wider heating pattern. In my 25-foot travel trailer, this broader distribution eliminated the cold corner near the bathroom that plagued my previous heater setup.
Flexibility extends to fuel options. The unit runs on standard 1-pound cylinders for portability or connects to a 20-pound tank with an accessory hose. This dual capability lets me switch between quick weekend trips and extended boondocking sessions without changing heaters.
Safety features include the oxygen depletion sensor and tip-over switch. The rugged safety guard protects the heating element from accidental contact, which is important in the tight quarters of an RV.
Who This Heater Is Perfect For
This heater suits RV owners who want maximum flexibility for heating their rig and other spaces. The tiltable design and 9,000 BTU output handle everything from hunting blinds to garage workshops to RV living.
Who Should Look Elsewhere
Reports of ignition issues and unexpected shutdowns make this risky for remote camping where reliability is critical. If you need proven dependability, the Mr. Heater products have stronger track records with significantly more user reviews.
8. Hotdevil 6200 BTU Catalytic – Best Value
Portable Propane Heater with Catalytic Burner for Camping...
6,200 BTU
Heats 200 sq ft
1.5 lbs
Upgraded Catalytic
Pros
- Affordable under $35 price
- Upgraded catalytic burner
- Adjustable temperature control
- Very lightweight at 1.5 lbs
- Prime eligible shipping
Cons
- Propane tanks not included
- Some quality control issues
- Canister fits loosely in base
- Requires separate gas lighter for ignition
- Goes through fuel quickly
At under $35, the Hotdevil offers an incredible value proposition. I was skeptical given the low price, but the upgraded catalytic burner produces clean, efficient heat that rivals heaters costing three times as much, making it a surprisingly strong contender among the best portable propane heaters for RVs living. This is my backup heater that lives in my emergency kit.
The adjustable temperature control valve lets you fine-tune the heat output between applications. I’ve used the lower settings for maintaining temperature and cranked it up for quick warming on chilly mornings. The 6,200 BTU output handles spaces up to 200 square feet effectively.
Weighing just 1.5 pounds, this heater disappears into my gear without adding noticeable bulk. The foldable legs and all-aluminum reflector design feel surprisingly sturdy for the price point. The brass connecting hose provides peace of mind against gas leaks.
Safety mesh guards protect against accidental contact with the heating element. The gas canister secure bracket holds the propane cylinder in place, though I’ve noticed the fit can be somewhat loose on some units.
Who This Heater Is Perfect For
This heater is ideal for budget-conscious campers who still want catalytic heating efficiency. It’s perfect for tents, small RVs, greenhouses, and emergency preparedness kits where the low price allows purchase of a backup heating solution.
Who Should Look Elsewhere
If you need a primary heater for regular use, the quality control issues and loose canister fit may become frustrating. The requirement for a separate gas lighter also adds a step that integrated piezo igniters eliminate.
Buying Guide: How to Choose the Best Portable Propane Heaters for Your RVs?
Selecting the right portable propane heater for RV living requires understanding several key factors. After years of testing and talking with fellow RV owners, I’ve identified the critical considerations that determine whether a heater will meet your needs.
BTU Requirements for Your RV Size
BTU (British Thermal Unit) output determines how much space a heater can warm effectively. Here’s a general guideline for RV applications:
Small RVs and camper vans under 150 square feet need 3,000-4,000 BTU. Mid-size travel trailers and fifth wheels between 150-250 square feet require 4,000-9,000 BTU. Large RVs over 250 square feet may need multiple heaters or the 9,000+ BTU models.
Remember that portable propane heaters work best as supplemental heat sources. For extreme cold below 20 degrees, you’ll likely need your RV furnace in addition to a portable heater.
Essential Safety Features
Safety cannot be compromised when using propane heaters in enclosed RV spaces. Look for these critical features:
Oxygen Depletion Sensor (ODS) automatically shuts off the heater when oxygen levels drop below safe thresholds. This is non-negotiable for indoor RV use. Tip-over protection ensures the heater shuts down if knocked over, preventing fires. Carbon monoxide detector usage alongside any propane heater is strongly recommended for additional protection.
Fuel Efficiency and Runtime
Runtime varies dramatically based on BTU setting and propane tank size. A 1-pound propane cylinder typically provides 2-6 hours of heat depending on the setting. A 20-pound tank can run a heater for 24-50 hours at moderate settings.
Catalytic heaters like the Camco Olympian series offer superior fuel efficiency compared to radiant models. If you boondock frequently, this efficiency translates to fewer propane refills and lower operating costs.
Ventilation Requirements
All portable propane heaters require ventilation when used indoors. Crack a window at least one inch to allow fresh air circulation. This prevents carbon monoxide buildup and ensures adequate oxygen for both the heater and occupants.
Never seal your RV completely when running a propane heater. The combustion process consumes oxygen and produces water vapor, which leads to condensation issues without proper airflow.
High Altitude Performance
Many propane heaters struggle above 7,000 feet elevation due to reduced oxygen levels. The ODS may trigger false shutdowns, leaving you without heat when you need it most. If you camp regularly in mountainous regions, research altitude-specific models or consider diesel heaters as alternatives.
Condensation Management
Propane combustion produces water vapor – approximately 0.81 gallons of water per gallon of propane burned. In an enclosed RV, this moisture condenses on windows, walls, and cold surfaces, potentially leading to mold and mildew.
To manage condensation, maintain ventilation, use moisture absorbers like DampRid, and consider running a small dehumidifier. Catalytic heaters produce less moisture than radiant models, making them better choices for moisture-conscious RV owners.

Frequently Asked Questions
How long will a 15000 BTU heater run on a 20 lb propane tank?
A 15,000 BTU heater running on a 20 lb propane tank will last approximately 14-16 hours at full output. A 20 lb propane tank contains about 4.7 gallons of propane, and propane produces roughly 91,500 BTU per gallon. At 15,000 BTU per hour, you’ll consume about 0.16 gallons per hour, giving you roughly 29 hours of runtime at full capacity. However, most heaters cycle on and off, so actual runtime is typically 20-30 hours depending on outside temperature and thermostat settings.
Can you use a portable propane heater in a camper?
Yes, you can safely use a portable propane heater in a camper if you follow proper safety guidelines. Choose a heater rated for indoor use with an oxygen depletion sensor (ODS) and tip-over protection. Always maintain ventilation by cracking a window at least one inch. Never run the heater while sleeping without a carbon monoxide detector present. Most RV owners use portable propane heaters as supplemental heat alongside their built-in furnace for optimal safety and efficiency.
What is the cheapest way to heat an RV in the winter?
The cheapest way to heat an RV in winter depends on your situation. For boondockers with limited electricity, portable propane heaters offer the most cost-effective solution at roughly $2-4 per day for propane. If you have shore power, electric space heaters cost less to operate at about $1-3 per day depending on electricity rates. Combining methods works best – use your RV furnace for morning warm-up, a portable propane heater during the day, and extra insulation like Reflectix on windows to reduce heat loss by 20-30%.
How long will a 20 lb propane tank last for heating an RV?
A 20 lb propane tank lasts 24-50 hours when heating an RV with a portable propane heater, depending on the BTU setting and outside temperature. At 9,000 BTU on high, expect about 14-16 hours of runtime. At 4,000 BTU on low, you’ll get 30-35 hours. For RV furnaces which typically run at 30,000-40,000 BTU, a 20 lb tank might only last 8-12 hours of actual burner time. Temperature, insulation quality, and thermostat settings significantly impact actual runtime.
Final Thoughts
Finding the best portable propane heaters for RVs living comes down to matching your specific needs with the right combination of BTU output, safety features, and portability. The Mr. Heater Portable Buddy remains my top recommendation for most RV owners, offering proven reliability, excellent heat output, and comprehensive safety features backed by over 31,000 reviews.
For smaller spaces or tighter budgets, the Little Buddy delivers surprising performance in a compact package. Those prioritizing silent operation and fuel efficiency should consider the Camco Olympian catalytic series despite the premium price. Whatever you choose, always prioritize safety with proper ventilation and carbon monoxide detection.
