6 Best RV Propane Heaters for Winter Camping Trips
Stay warm this winter with our top 6 RV propane heaters. We evaluate efficiency, safety features, and ease of use to help you choose the best for your trip.
There is nothing quite like the biting chill of a mountain morning to remind you that your RV’s insulation is only as good as your heating source. Choosing the right propane heater is the difference between a cozy, restorative winter retreat and a shivering, moisture-ridden nightmare. Let’s break down the best systems to keep you warm while you navigate the realities of off-grid winter living.

Suburban NT-Series: Reliable Forced Air Heating
This Suburban NT-20SEQ furnace offers efficient direct air discharge for zone heating in smaller spaces. Featuring direct spark ignition and sealed, forced-draft combustion, it requires an interior-mounted wall thermostat (sold separately) and includes a 2-year limited warranty.
The Suburban NT-Series is the industry standard for a reason: it is the workhorse of the RV world. These forced-air furnaces are designed to be ducted throughout your rig, ensuring that heat reaches your holding tanks and basement compartments, which is crucial for preventing frozen pipes.
If you are a full-timer who spends significant time in sub-freezing temperatures, this is the gold standard. It’s robust, parts are available at almost any RV shop, and it effectively manages the "whole-house" heating experience. Just be prepared for the audible cycling of the fan, which can be a bit intrusive during quiet nights.
Propex HS2211: Efficient Underfloor Gas Heater
When interior space is at a premium, the Propex HS2211 is a masterclass in clever engineering. By mounting this unit externally—usually under the floor—you reclaim valuable interior storage that would otherwise be lost to a bulky furnace box.
This heater is exceptionally efficient with both battery power and propane consumption, making it a favorite for van conversions and smaller campers. It pulls fresh air from outside, heats it, and pushes it into the cabin, which creates a much drier heat than internal combustion units. If you prioritize floor space and energy efficiency, this is your best bet.
Atwood Everest Star: Compact Vertical Furnace
The Atwood Everest Star is designed for the tightest of footprints, utilizing a vertical configuration that fits into shallow wall cavities. It’s a classic choice for older rigs or custom builds where horizontal space is simply not available.
While it lacks the sheer power of larger residential-style furnaces, it punches well above its weight class for its size. It’s a reliable, no-nonsense heater for those who need a direct replacement or a space-saving solution in a smaller travel trailer. It’s not the quietest unit on the market, but its longevity and compact design make it a solid, utilitarian choice.
Empire Comfort Systems: Radiant Wall Heating
Empire Comfort Systems offers a different approach with their vent-free radiant wall heaters. Instead of blowing air around, they radiate heat directly into the living space, creating a sensation similar to standing in front of a fireplace.
These units are incredibly quiet and require no electricity to operate, which is a massive advantage for boondockers. However, because they are vent-free, you must be diligent about cracking a window for oxygen intake. If you want silent, reliable heat without the constant hum of a fan, this is an excellent, albeit space-demanding, option.
Camco Olympian Wave 3: Silent Catalytic Heat
The Camco Olympian Wave 3 is the darling of the off-grid community, and for good reason. It uses catalytic technology to produce heat without an open flame, meaning it is whisper-quiet and extremely fuel-efficient.
Because it operates silently and consumes no electricity, it is perfect for overnight use in smaller spaces. You will need to be comfortable with mounting it securely and managing the inherent moisture that comes with vent-free propane combustion. If you value silence and efficiency above all else, the Wave series is hard to beat.
Mr. Heater Buddy: Portable Radiant Solution
The Mr. Heater Buddy is the ultimate "just in case" heater for the nomadic lifestyle. It’s portable, affordable, and requires no permanent installation, making it the perfect backup for when your primary furnace decides to quit.
While it is excellent for taking the edge off a chilly morning, it should not be your primary heating source for long-term winter living. It lacks the thermostat control and external venting of installed systems, which can lead to rapid condensation buildup. Keep one on hand for emergencies, but don’t rely on it as your sole thermal solution.
Assessing BTU Needs for Your Specific RV Size
Calculating your BTU (British Thermal Unit) requirement is not just about the square footage of your RV. You must factor in the quality of your insulation, the number of windows, and the ambient temperature of your destination.
A common mistake is buying the largest heater possible, which leads to "short-cycling." This is when a heater turns on and off too rapidly, failing to properly heat the interior or remove moisture. Always aim for a heater sized appropriately for your rig’s cubic volume to ensure consistent, comfortable temperatures.
Safe Installation and Proper Gas Ventilation
Propane safety is non-negotiable. Whether you are installing a forced-air furnace or a wall-mounted unit, you must ensure that all gas lines are pressure-tested and free of leaks.
Proper ventilation is the second pillar of safety. Even if a manufacturer claims a unit is "safe for indoor use," you must have a high-quality carbon monoxide detector installed and functional at all times. Never bypass safety sensors or attempt DIY modifications to the combustion intake or exhaust ports.
Managing Moisture and Preventing Condensation
Propane combustion naturally releases water vapor as a byproduct. In a small, sealed RV, this can quickly lead to damp walls, mold, and ruined upholstery.
To combat this, you must prioritize airflow. Even when it is freezing outside, keep a roof vent slightly cracked or use a dedicated moisture absorber. If you are using a vent-free heater, proper ventilation is not just a suggestion—it is a requirement for your health and the integrity of your rig.
Essential Winter Maintenance for Gas Heaters
Before the first frost hits, perform a "dry run" of your heating system. Check your burner for spider webs or debris, which are common culprits for ignition failure.
Ensure your propane tanks are filled and your regulator is functioning correctly. If you have a forced-air system, clean the intake filters to ensure maximum efficiency and airflow. A little preventative maintenance in the autumn saves you from a frozen night in the dead of winter.
Winter camping is a rewarding way to experience the outdoors, provided you have the right thermal foundation. By balancing your heating needs with proper ventilation and maintenance, you can turn your RV into a warm sanctuary regardless of the temperature outside. Choose your system wisely, stay safe, and enjoy the quiet stillness of the winter season.
