When it comes to selecting the right RV heating system, the variety of options can feel overwhelming. Who knew there were so many choices? To help cut through the confusion, we’ve pulled together a guide to the most popular options, breaking down the pros and cons of each. By the end, you'll be one step closer to finding the perfect heating system for your setup and style of travel.
What to Consider When Choosing an RV Heating System
Staying warm on the road means choosing a heating system that suits your unique setup. Here are some of the key factors you should consider to ensure maximum comfort and efficiency:
Size & Occupancy: The size of your RV and the number of people on board will heavily influence the necessary BTU output and power draw of your heating system. After all, a cozy camper for two has totally different needs than a sprawling motorhome for the whole family. Larger RVs typically need systems with higher BTU output to keep everyone comfortable.
Climate Conditions: Think about where you’ll be going and what kind of weather you’ll meet along the way. Those heading to snowy mountain getaways might need a high-powered furnace, while fair-weather travelers can often get by with a more fuel-sipping unit.
Personal Comfort: Some people want their RV to feel warm and toasty, no matter the cost, while others are more comfortable with cooler temperatures and can tolerate a chillier interior. Consider how much heat you'll truly need to stay comfortable and whether you're willing to invest in a stronger system for those extra cozy nights.
Budget: High-end systems often come with high-end price tags. Weigh the costs against your needs to help decide where the best value is for your RV lifestyle.
Considering these factors will help you find the best fit to stay warm and comfortable, no matter the elements. Now, let’s dig into the choices and see what’s available.
Types of RV Heating Systems
Different RV heating systems come with unique advantages and trade-offs. Here’s a closer look at the top options, with pros, cons, and suggestions to guide your decision.
RV Furnace
When it comes to staying warm and cozy on a winter RV trip, the forced air furnace is often the MVP. These powerful units are typically pre-installed in most recreational vehicles, providing a reliable and efficient heating solution for the chilly months.
Pros
Quick, Powerful Heating: An RV furnace circulates warm air rapidly throughout the cabin and even into “wet” areas, like the camper’s underbelly, where plumbing and tanks are. This is the fastest and strongest heating option, ideal for taking the chill off as soon as you arrive at your campsite.
Safe for Day Trips: RV furnaces can operate safely even when you’re not physically present in the camper, allowing you to venture out for the day and not worry about returning to a freezing cold space.
Cons
Noisy Operation: Forced air furnaces can be noisy, which may be a drawback for light sleepers.
Energy Efficiency: They consume both electricity and propane quickly, making them less efficient than other options. However, some newer models are designed to reduce noise and draw less power, improving both comfort and efficiency.
Top Picks
For quality and reliability, Suburban and Dometic are leading brands in RV furnaces, known for manufacturing high-performing units that keep you toasty, no matter how cold it gets outside.
RV Diesel Heater
RV diesel heaters have been steadily gaining popularity in recent years, particularly among owners of Class B camper vans and other compact recreational vehicles. At their core, these RV heating systems work by using the vehicle's own diesel fuel to generate heat, which is then circulated throughout the camper’s interior—often through a single vent. This obviously makes for a convenient and compact option, eliminating the need to set up an additional fuel cell and multiple ducts and vents.
Pros
Efficient and Powerful: Diesel fuel is more energy-dense than propane, giving these heaters an edge in efficiency and heating power.
Space-Saving and Compact: Diesel heaters connect directly to your RV’s fuel system, eliminating the need for bulky propane tanks and freeing up valuable storage space.
Safer than Propane: Diesel is less volatile than propane, posing a lower risk of leaks or explosions.
Cons
Not Ideal for High Elevations: Diesel heaters struggle at high altitudes and require an adjustment to be made in order to operate safely. Not recommended for elevations over 8,000 feet.
Noise Factor: Diesel heaters can produce a persistent ticking noise from the fuel pump, which may bother some campers.
No Automatic Shut-Off: Unlike some systems, diesel heaters don’t turn off automatically once your rig reaches a set temperature.
Top Picks
Webasto is a highly-rated brand known for reliable performance and durable diesel heating systems.
Keep in mind that if this is how you are planning to heat your RV in the winter, the exhaust on a diesel heater must vent directly outside the camper and be placed such that harmful gases cannot be sucked back in the air intake. Always install a carbon monoxide (CO) detector for safety!
RV Electric Heat Pump
RV electric heat pumps are a specialized component of the air conditioning system in many recreational vehicles. These heat pumps serve a dual purpose, providing both cooling and heating functionality for the RV interior. Unlike traditional furnaces, which generate heat, heat pumps work by transferring heat from the outside air into your RV, making them an efficient option for mild winter weather.
Pros
Energy Efficient: Heat pumps consume less energy than traditional furnaces, providing heating at a fraction of the cost, which is especially beneficial for RVers who spend extended periods boondocking or using limited shore power.
Dual Functionality: Offers the convenience of year-round climate control, allowing users to seamlessly transition from cooling to heating modes as the weather changes.
Cons
Limited Effectiveness in Extreme Cold: Heat pumps may struggle to provide adequate warmth in extremely cold climates, making them less ideal for harsh winter conditions.
Higher Upfront Cost: Heat pumps tend to be more expensive than standard furnaces, although the long-term savings on energy can help offset this cost over time.
Not Always Included: Not all RV air conditioning units come equipped with heat pump capabilities, so be sure to consider this when upgrading or replacing your A/C system.
Top Picks
Leading brands in the RV heat pump market include Coleman-Mach and Dometic. These manufacturers are known for producing high-quality, rugged units designed specifically for the rigors of RV use.
RV Electric Fireplaces
RV electric fireplaces are a popular feature found in many modern recreational vehicles, providing a cozy ambiance and supplemental heating source for the cabin. Wired directly into the RV's electrical system, these built-in units offer a safer alternative to portable space heaters while enhancing comfort.
Pros
Convenient Warmth: With the simple press of a button or flip of a switch, you can instantly generate soothing flames and radiant heat.
Atmospheric Comfort: Electric fireplaces create a warm, inviting atmosphere without the need for wood or gas, making them ideal for chilly evenings on the road.
Adjustable Heat Settings: Many models feature customizable heat settings, allowing you to customize the temperature to your liking.
No Venting Required: Since they operate on electricity rather than combustible fuels, there’s no need to worry about venting or other complex installation requirements.
Cons
Dependence on Power Supply: Electric fireplaces do require a steady power supply to operate, so they may not be suitable for extended off-grid camping trips where shore power or generator access is limited.
Energy Consumption: Some models can be quite energy-intensive, straining the RV’s battery bank if not carefully monitored.
Limited Heating Range: Electric fireplaces are generally effective at heating the main living space, but do a poor job of reaching bedrooms or bathrooms, especially in larger rigs.
Top Picks
When it comes to reliable RV electric fireplace manufacturers, Furrion is a top choice known for producing durable, high-quality units.
Portable Heaters
Many folks like the convenience, ease, and affordability of portable heaters as a short-term heating solution for their RVs. When choosing one, you have two main power options: electric or propane.
Electric portable heaters include ceramic, oil-filled, or fan-forced designs to generate heat. One thing to note is that these units need to be plugged into shore power or your generator in order to operate. Propane heaters, by contrast, can be powered by a portable propane tank or can be plumbed into your RV’s propane line. They come in radiant, tank top, forced air, or catalytic designs. Keep in mind these heaters emit dangerous carbon monoxide as a byproduct, so it’s critical you have proper ventilation, along with fully-functioning smoke and CO detectors.
Pros
Compact and Versatile: Perfect for heating small spaces quickly, and easy to move from one area to another as needed.
Affordable: A wide range of budget-friendly options are available to suit different needs.
Cons
Limited Heat Coverage: Concentrated heat output means they may struggle to evenly heat larger RV interiors.
Power Consumption: Depending on the model, they can drain your RV’s propane or electrical system quickly.
Require Close Supervision: Portable heaters should not be left running unattended, particularly overnight or while you’re away from the RV.
Top Picks
