Heating Your Car-Camper: Off-Grid Methods For Warmth

There are several ways to heat a camper without electricity. One way is to use a propane furnace, which is commonly found in RVs and motorhomes. These furnaces use propane gas for heat and only require a small amount of electricity to regulate temperature. Another option is a portable space heater, which can be powered by propane or electricity. If you're looking for a more off-the-grid solution, a wood stove can be installed in your camper, but it requires cutting a hole in the wall or ceiling for the chimney. Additionally, proper insulation is key to retaining heat. This includes sealing any openings, installing a skirt around the undercarriage, and adding rugs and heavy curtains to your windows and doors.

Insulate your camper van with rugs, curtains, and bubble wrap

Insulating your camper van is a great way to keep the heat in and the cold out. Here are some tips to insulate your camper van using rugs, curtains, and bubble wrap:

Rugs

Adding rugs to your camper van floor will not only make the space feel warmer and more inviting but also act as an extra layer of insulation. Thick, plush rugs will help trap heat inside the van, preventing it from escaping through the floor. This is especially useful if your van has metal floors, which can get very cold in winter. When choosing rugs, opt for thick, dense materials such as wool or synthetic fibres. Make sure the rugs are large enough to cover most of the floor space, and consider layering multiple rugs for added insulation.

Curtains

Curtains are an excellent way to insulate the windows of your camper van. They can be made from various materials, such as cotton, canvas, or even thermal fabrics specifically designed to retain heat. Curtains with a reflective backing are a great option, as they will reflect heat back into the van while also blocking out sunlight to keep the interior cool during hot weather. Curtains can be hung using tension rods or adhesive hooks, ensuring a snug fit to minimise heat escape.

Bubble Wrap

Bubble wrap is a versatile and effective insulation material for camper vans. It can be used on walls, floors, and even windows to trap heat and create a cosy environment. Metallic bubble wrap, such as Reflectix, is a popular choice for van insulation. It is easy to work with and can be cut to fit any shape. When installing bubble wrap insulation, use spray adhesive or aluminium tape to secure it to the walls and floors. For windows, you can cover the glass with bubble wrap, providing insulation while still allowing some natural light to enter. Remember to leave some gaps for ventilation to prevent carbon monoxide build-up if you are using a heater.

By combining rugs, curtains, and bubble wrap insulation, you can effectively insulate your camper van, making it warmer and more comfortable during cold weather adventures. A well-insulated van will also help reduce noise from the outside, creating a peaceful and quiet space to relax and enjoy your travels.

Use a propane heater

Propane heaters are a great way to heat your camper without electricity. They are versatile, compact, and can be used for heating, cooking, or both at the same time. You can find them at your local hardware store or online. Here are some tips and guidelines for using a propane heater in your camper:

Types of Propane Heaters

There are two main types of propane heaters commonly used in campers: portable propane heaters and catalytic heaters.

Portable Propane Heaters

These heaters are small, indoor-safe, and can easily warm up small areas. Look for heaters with safety features such as automatic shut-off if they fall over or if oxygen levels in the room are too low. The Mr. Heater MH9BX, for example, is a popular indoor-safe propane radiant heater.

Catalytic Heaters

Catalytic heaters use a chemical reaction to produce heat and are considered safer as they don't produce a flame or fumes. However, they can be pricier and pose a fire risk if items are allowed to rest against them.

Safety Precautions

When using a propane heater, it is important to follow these safety guidelines:

• Ensure proper ventilation in your camper to prevent the buildup of dangerous gases.
• Keep flammable items, such as clothing, tissues, or towels, away from the heater.
• Have a fire extinguisher and carbon monoxide detector in your camper.
• Never leave a propane heater unattended or running while sleeping.

Insulation

To maximize the efficiency of your propane heater, it is important to ensure proper insulation in your camper. Here are some tips:

• Seal any openings or cracks in your camper using caulk or weather stripping to prevent cold air from leaking in.
• Install an RV skirt to insulate the undercarriage and prevent heat loss through the floor.
• Upgrade the insulation in your floor, ceiling, and walls if possible.
• Use heavy insulating curtains or reflective insulated panels on windows and doors.
• Place rugs on the floor to add an extra layer of insulation.

Other Considerations

• Be aware of moisture buildup, as propane heaters produce "wet" heat, which can lead to mold and mildew. Consider using a dehumidifier to control humidity levels.
• Propane heaters require some electricity to ignite the flame and run the fans. Ensure you have a power source, such as a 12V battery, to operate the heater.

Try a catalytic heater

If you're looking for a way to heat your car for camping without electricity, a catalytic heater could be a perfect solution. Here's everything you need to know about using a catalytic heater safely and effectively.

Catalytic heaters use a chemical reaction instead of a flame to produce heat. This reaction typically involves a catalyst, oxygen, and fuel, such as propane or natural gas. The catalyst is often a platinum-coated plate that can be reheated. When the propane mixes with oxygen in the air and comes into contact with the platinum surface, it creates a chemical reaction that generates heat. This process is flameless and doesn't produce dangerous carbon monoxide or fumes.

Safety Precautions

While catalytic heaters are generally safe, it's important to follow these precautions:

• Read the instructions carefully and follow any guidelines provided by the manufacturer.
• Ensure proper ventilation in your car. Even though catalytic heaters produce minimal carbon monoxide, providing adequate ventilation is crucial.
• Maintain a safe distance between the heater and other objects. Catalytic heaters can get very hot, so keep bedding, clothing, and other flammable materials away from the heater.
• Always turn off the heater when it's not in use and never leave it unattended.
• If you're concerned about carbon monoxide, opt for a heater with a special sensor that measures oxygen depletion and shuts down the heater if necessary.
• Keep the heater away from moisture and water.

Choosing the Right Catalytic Heater

When choosing a catalytic heater, consider the size of your car and the amount of space you want to heat. Larger cars or spaces will require a more powerful heater, possibly with a fan to increase heat flow. Also, consider the type of fuel used and opt for heaters that use the same propane bottles as your other camping gear to avoid packing and carrying separate fuel bottles.

Recommendations

The Mr. Heater "Little Buddy" 3800 BTU catalytic heater is an excellent choice for small spaces, such as a 2-person tent. It runs for up to 5.5 hours on a 16-ounce propane bottle and features safety measures like a low-oxygen sensor and an accidental tip-over switch with auto shut-off. For larger spaces, the Mr. Heater "Big Buddy" 4000-9000-18000 BTU catalytic heater is a better option. It has a higher BTU output, a fan for improved heat flow, and similar safety features.

Seal windows, vents, and doors with tape, film, or foam

Sealing windows, vents, and doors is an important step in keeping your camper warm. This process helps to keep cold air out and prevent heat loss. There are several methods you can use to seal these areas effectively:

Tape

Foam tape is an excellent option for sealing windows, vents, and doors in your camper. It is designed to be soft and low-density, making it easy to conform to the surfaces you need to seal. Look for automotive-grade foam tape designed for HVAC vents, or gasket tape, which is an adhesive-backed silicone foam or closed-cell silicone sponge that provides an airtight seal. When applying the tape, ensure you remove any existing seals or rubber first, clean the area, and then apply the tape from one corner to the other, pressing down to ensure a strong hold.

Film

Window insulation film is another affordable and effective way to seal your windows. First, clean the window area and let it dry. Then, apply adhesive tape around the entire window, leaving a 1-inch space from the window frame. Cut a plastic film sheet to size, leaving a 5-inch excess. Press the plastic sheet onto the taped frame, ensuring no gaps are present. Use a hairdryer on high heat to remove any wrinkles from the plastic.

Foam

To seal roof vents, you can use thermal vent insulators made of foam. These insulators are designed to fit into the vent openings and help prevent heat loss. Additionally, if you don't mind blocking your windows, you can use styrofoam or bubble pack insulation to cover them, providing an extra layer of insulation.

Use a portable battery to power an electric heater

Using a portable battery to power an electric heater is not the most efficient method of heating a camper without electricity. Heaters draw a lot of power, and you would need a large battery station to power even a small under-desk space heater.

However, if you are set on using a portable battery to power an electric heater, there are a few things to keep in mind. First, ensure that you have a large enough battery to power the heater for the desired amount of time. Second, be mindful of the power draw of the heater and the capacity of the battery, as you may need to recharge the battery frequently. Additionally, always follow safety guidelines when using any heating device, and be cautious of carbon monoxide, a colorless and odorless gas that can be fatal if inhaled. Ensure proper ventilation and consider using a carbon monoxide detector for safety.

When using a portable battery to power an electric heater, it is essential to prioritize safety and efficiency. Make sure to choose a heater with a low power draw, and consider using it in conjunction with other heating methods, such as insulation, warm bedding, or a propane furnace, to reduce the overall power demand. Remember to follow all safety guidelines and take the necessary precautions to enjoy a warm and comfortable camper without electricity.

It is worth noting that using a portable battery to power an electric heater may not be the most sustainable option due to the frequent recharging requirements. In the long run, it may be more cost-effective and environmentally friendly to consider alternative heating methods or invest in a more permanent power solution, such as solar panels or a generator.
