Heat a Camper Without Electricity

3 Ways to Heat a Camper Without Electricity

Updated on February 9th, 2024

Trying to stay warm can be challenging if you love cool-weather camping, but your destinations don’t have the electricity to run a heater. The solution to this issue is to find alternate ways to heat your RV. To assist, we put together the best and safest options below for all types of recreational vehicles.

Keeping your camper cozy and warm without electricity when the temperatures drop can extend your camping season, so it’s worth knowing all your options.

The 3 Best Ways To Heat A Camper Without Electricity

A propane heater in an RV

1. Run the RV Furnace

If your camper has a furnace, it most likely uses propane as a heat source, which you can run as long as there is a charge on your house battery.

You may wonder if an RV furnace needs electricity to operate. The furnace does require an electrical power source to start the igniter and fans, but the system can use the 12-volt power from the house battery for these tasks when the RV isn’t on shore power.

Of course, you’ll need to ensure you have enough propane and battery power to keep the furnace running so the camper can stay warm.

We are often asked, “How long will my RV furnace run on battery power?”

The answer is that with a full charge on a deep-cycle 12-volt battery, a propane furnace will operate for about 11 hours. Depending on your camping situation, you may need to bring a secondary charged battery to keep the heat on while the first battery recharges via a solar panel, generator, or power station.

As for propane use, a single 20-pound tank should run a 50,000 BTU furnace for six to eight hours of continual operation. Luckily, many modern RVs have better insulation, so the furnace only needs to kick on the burner a few times an hour to maintain interior warmth. This run time reduction of the burner means the propane tank should last much longer than eight hours.

However, that doesn’t take into consideration the use of propane for other RV tasks, such as cooking or running the water heater or refrigerator. Having an extra propane tank or two for heating on extended camping trips is smart if there isn’t a refill station near your campground.

2. Use a Portable Gas Space Heater

If you want to know how to heat a teardrop trailer, pop-up camper, or other travel trailer or motorhome without a furnace or electricity, the easiest way is to use a portable gas space heater.

Portable camping heaters typically run on propane or butane canisters you attach to the heating unit. The heaters run very efficiently to conserve fuel and reduce harmful emissions that form as the gas burns. Most portable heaters will operate on a canister of fuel for between three to seven hours, depending on the heat level, so ensure you pack enough spares to last your entire trip.

Using a camping heater will require the following safety precautions: cracking a window for ventilation, installing a CO2 detector in your camper, and keeping the unit safe from flammable materials or kids and pets. Depending on the size of your teardrop, motorhome, or travel trailer, you can find a suitable portable space heater to match the square footage so the entire interior stays warm.

Even a small propane space heater can do a great job providing a heated trailer so you and your camping guests can stay comfortable. However, leaving a space heater on in your RV is never safe if no one is inside to monitor the situation.

3. Install A Wood Burning Stove

Wood-burning stoves are not only safe for RVs when installed properly, but they are also an excellent way to heat a camper with no electricity.

People who often camp in the coldest regions find a wood-burning stove very efficient and budget-friendly since you can scavenge wood to burn for free versus having to pay for propane gas. Plus, many stove models feature a cooking surface and a place to keep coffee or tea hot.

With the correct ventilation, a wood stove won’t choke the RV interior with smoke or soot. Instead, you can enjoy the wonderful flickering flames and crackling of the wood that creates a relaxing atmosphere.

You will need room inside your camper to install a wood stove, but luckily, they come in many different styles, sizes, and fuel-burning options. You can find compact units that burn wood pellets to larger residential-size models that take full-size logs.

Wood stoves require a vent pipe through the camper wall or roof, so it will take more time and work to install and seal off the gaps in the exterior. You’ll also need to have the area around the stove fireproofed and secure it to the floor to prevent movement while driving.

While many people install a DIY wood stove in their RV, leaving it to a professional may be best. Experts understand how wood-burning stoves operate, so they perform to optimal levels while keeping camper occupants safe from fumes, smoke, or accidental burns.

Why You Should Upgrade in RV Insulation and Weatherproofing

It’s incredible how fast the interior of a standard camper can warm up just from the body heat and breath of the occupants without electricity involved. You can use the information to your advantage if you want a heated trailer on camping trips in the cold months without relying as much on alternative options when electricity isn’t available.

The first step to increasing heat retention inside your camper is to caulk or fill cracks or gaps that allow drafty cold air to enter.

The next step is adding more insulation to the walls, ceiling, and undercarriage where possible. This can be as simple as attaching temporary rigid foam insulation panels over the areas. If you’re doing a major RV interior renovation, you can increase insulation behind the wall and ceiling panels.

Another easy way to keep the cold air from penetrating through vents, skylights, and windows is to add a thermal foil insulation product such as SmartShield. The material comes in sheets or on a roll and is flexible yet firm enough to cut to fit window frames and other areas where you want to block heat loss. If you measure correctly, you can push the material into the space, and it will stay without the need for tape or screws, which allows you to remove it when you want daylight or see out them while driving your camper.

If your RV floors do not have carpet, add area rugs during cold weather. A thick rug will create an extra barrier to trap heat and keep your feet toasty.

Lastly, add or swap thin curtains with ones that offer a thermal barrier. You can close them over the windows and block a surprising amount of cool air. In addition, they work just as well in hot months to stop heat penetration so your RV will stay cooler.

Many people find making these changes inside their camper goes a long way toward keeping the interior much warmer, and then adding in their body heat is enough to raise the temperature to a comfortable level.

An RV furnace typically requires a 12-volt power source to operate, consuming around 3-4 amps per hour when the furnace is running.

The duration it can run on a full charge of a deep-cycle 12-volt battery depends on the battery’s capacity, but for a 100Ah battery, it would be approximately 25-33 hours, assuming the furnace is the only appliance in use and the battery is fully charged.

  1. What safety measures should be taken when using a portable gas space heater in a camper, and how efficient are these heaters in fuel consumption?

When using a portable gas space heater in a camper, it’s crucial to ensure proper ventilation to prevent carbon monoxide buildup, keep flammable materials away from the heater, and never leave it unattended.

In terms of efficiency, while these heaters can be quite effective in heating small spaces, they can consume a significant amount of fuel, especially if used continuously, so it’s important to use them judiciously to conserve fuel.
