Top 5 Best Campervan Propane Heaters
10 Best Campervan Propane Heaters Review
1. Mr. Heater 9,000 BTU Portable Buddy Radiant Propane Heater
The Mr. Heater Portable Buddy is perhaps the most iconic choice for van dwellers seeking a dependable indoor heating solution. This compact, 7.1-pound radiant heater is the go-to choice for warming small spaces up to 225 square feet, making it an excellent candidate for many campervan layouts. It offers two heat settings—4,000 or 9,000 BTU/hr—providing flexibility for various outdoor temperatures. Its primary selling point is its exceptional portability and built-in safety features, including an emergency low oxygen safety system (ODS) and a tip-over shut-off, which are crucial for enclosed environments.

5. Mr. Heater 3,800 BTU Little Buddy Portable Radiant Propane Heater
The Mr. Heater Little Buddy is the smallest and most compact member of the “Buddy” family, delivering a modest 3,800 BTUs per hour and capable of heating up to 95 square feet. This heater is specifically designed for ultra-compact spaces and minimalists.

How to Choose Best Campervan Propane Heaters
Propane heaters are highly favored by the van life community because they offer immediate, powerful heat and function without draining precious house battery power. Choosing the right heater for your mobile home is not just about comfort; it is a critical safety decision. The Best Campervan Propane Heaters must balance BTU output with the small, enclosed space of a vehicle. A unit that is too large can overheat your living area and consume fuel rapidly, while one that is too small won’t keep you warm in winter weather. Ultimately, the perfect choice hinges on your van’s size, insulation, and the climate you frequently travel in, so picking the right model matters immensely for your health and comfort on the road.
BTU Rating and Vehicle Size
BTU (British Thermal Unit) is the measure of heat output. For van life, matching the BTU to your square footage is essential. Generally, 4,000 BTUs is sufficient for a small, well-insulated van (under 100 sq. ft.), while larger RVs or poor insulation may require 9,000 BTU or more. An oversized heater can lead to short-cycling and condensation issues. Always check the heater’s square footage rating to ensure optimal performance and fuel efficiency before you make a purchase.
Essential Safety Features (ODS and Tip-Over)
Safety is paramount when using propane indoors. Look specifically for the Oxygen Depletion Sensor (ODS), which automatically shuts the heater off if the oxygen level in the space drops too low, preventing carbon monoxide buildup. Secondly, a tip-over safety switch is non-negotiable for a portable unit in a moving vehicle. These features are legally required on many indoor-safe propane heaters and should be your absolute first consideration to protect yourself and your family. For more information on safely implementing gas appliances, check out this guide on the pros and cons of propane heaters.
Fuel Source and Run Time
Propane heaters typically run on either disposable 1 lb cylinders or refillable 20 lb tanks. 1 lb cylinders are portable and easy to swap but costly and create waste over time. A 20 lb tank connected via a hose and regulator offers better fuel economy and vastly longer run times, which is ideal for sustained cold-weather camping. Consider how frequently you want to refill or swap tanks; for extended off-grid stays, an external 20 lb tank connection is often the most convenient and cost-effective choice for your Best Campervan Propane Heaters.
Heating Method (Radiant vs. Convection)
Radiant heaters (like the ‘Buddy’ series) provide immediate, directional warmth by heating objects and people directly. They are great for spot-heating or quick warm-ups. Convection (or Blue Flame) heaters, like the ProCom, heat the air, allowing it to circulate for more uniform warmth throughout the entire cabin. For small vans, radiant heat can be more efficient, but for larger, open spaces, a convection heater provides a more consistent, gentle ambient temperature, often ideal for sleeping.
Portability and Storage Footprint
In a campervan, every inch of space is valuable. Portable propane heaters range from the ultra-compact Little Buddy to large cabinet models. For minimalists, prioritize a small, lightweight heater that can be easily stowed away when not in use. If you choose a larger model, ensure it has features like wheels or a built-in handle for safe movement. Always select a heater whose footprint allows for safe operation—away from flammable materials—in your specific vehicle layout.
Propane Heater Maintenance and Best Practices
Proper maintenance of your Best Campervan Propane Heaters is crucial for both longevity and safety. One of the most common issues is dust buildup on the ODS pilot sensor, which can cause the heater to prematurely shut off. Regularly inspect and gently clean the pilot light area with canned air. When not in use, store the heater in a dry, safe location. Furthermore, remember that all vent-free propane heaters introduce moisture into the air as a byproduct of combustion, which can lead to significant condensation inside your van. Using an electric dehumidifier or ensuring consistent cross-ventilation, even when running the heater, is essential to manage this moisture and prevent mold.
How to Use Best Campervan Propane Heaters
Using a portable propane heater in a confined space requires attention to detail. Follow these steps for safe and effective warmth in your campervan:
- Ensure proper setup by attaching a fresh 1 lb cylinder or connecting a hose to your external 20 lb tank, checking all connections for tightness.
- Use the heater on a flat, non-flammable surface, maintaining clearance from all curtains, bedding, or furniture, and follow the manufacturer’s suggested distances.
- Always maintain a small window or roof vent crack open (at least 1-inch) for fresh air. This is vital for the ODS to function properly and to minimize carbon monoxide risk, which is one of the key differences between gas and electric appliances.
- If the unit shuts off unexpectedly, allow it to cool, check the ODS pilot sensor for dust/debris, and confirm that there is adequate fresh air circulation before attempting to restart.
Frequently Asked Questions
Are Best Campervan Propane Heaters safe to use overnight?
Yes, many propane heaters with ODS and tip-over safety features are rated safe for indoor use, including overnight. However, it is paramount that you always ensure proper ventilation by cracking a window or ceiling vent. Never use a heater without these two critical safety features, and consider installing a battery-operated carbon monoxide detector for an added layer of safety in your van.
How long will a 1 lb propane cylinder last on a small heater?
For a typical small portable heater (like the 4,000 BTU setting on the Portable Buddy), a 1 lb propane cylinder will generally last between 5 and 6 hours of continuous use. When operating at a high setting (e.g., 9,000 BTUs), the run time dramatically decreases, often lasting only 2 to 3 hours. For overnight heating, a larger external tank connection is usually necessary for sustained warmth.
Do propane heaters cause condensation in a van?
Yes, propane heaters produce water vapor as a byproduct of combustion, leading to significant condensation on cold surfaces inside your campervan. To combat this, you must run your heater in conjunction with ventilation (like a cracked window or a roof fan set to exhaust). This practice allows the humid air to escape and fresh, drier air to enter, which is essential for both moisture control and safety.
What is the difference between Radiant and Blue Flame heat?
Radiant heat, characterized by a glowing panel, directly heats nearby objects and people, offering immediate, localized warmth. Blue Flame (convection) heat warms the air in the room, which then circulates for a more gentle and even overall ambient temperature. Radiant heaters are better for spot-heating, while Blue Flame heaters are superior for maintaining consistent, background heat in a slightly larger space.
Can I connect my small portable heater to a large propane tank?
Yes, most portable heaters like the Mr. Heater ‘Buddy’ series can be connected to a larger 20 lb propane tank. This requires purchasing a compatible, manufacturer-approved hose and regulator assembly specifically designed for that heater model. Using a larger tank significantly extends the run time, making it much more practical and cost-effective for full-time van life or extended camping trips.
Final Thoughts
Selecting the ideal propane heater is a fundamental step toward maximizing your comfort and safety while living the van life. Remember to prioritize safety features like the ODS and tip-over protection above all else. Next, match the BTU output to your vehicle’s size and insulation level to guarantee efficiency and prevent overheating. By considering these key elements—safety, size, and BTUs—you can confidently choose from the Best Campervan Propane Heaters and ensure your vehicle remains a cozy haven regardless of the weather outside.
For most campervan buyers, the Mr. Heater 9,000 BTU Portable Buddy Radiant Propane Heater offers the best balance of portability, necessary safety features, and heating power for standard-sized vans. If you need a more powerful, next-generation unit with wider heat distribution and premium features, choose the Mr. Heater Indoor Safe Portable Radiant Buddy Flex Heater for its 180-degree omni-directional warmth and enhanced safety systems, giving you maximum comfort on the road. This decision will help you make the best choice among the many Best Campervan Propane Heaters available.
