A crisp morning in the caravan, a rainy evening under the awning, or that chilly weekend in April: that’s when good heating makes the difference between just getting by and truly enjoying yourself. Choosing a camping heater, therefore, doesn’t start with the highest wattage, but with your camping vehicle, your campsite, and how you want to use the heat.
If you want to camp in comfort, heat strategically. You don’t need to turn your entire awning into a tropical oasis if you’re mostly sitting in your RV with a blanket and a book. And a small rooftop tent requires a different solution than a spacious RV. With the right choices, it stays comfortable, safe, and practical—exactly as a relaxing evening of camping should be.
The first question is simple: which space do you want to heat? A compact caravan, RV, or folding trailer heats up relatively quickly, especially when windows and doors are tightly closed. A large awning, a party tent, or an open canopy, on the other hand, constantly loses heat. In those cases, heating is primarily intended as pleasant supplemental heat, not as the main source of heat.
Also consider insulation. A modern RV with double-pane windows and good wall insulation requires much less heat from a heater than a lightweight tent with thin fabric. In a rooftop tent, limited space is also a factor: even a small difference in temperature can quickly feel comfortable there. That’s precisely why an adjustable setting is often more valuable than a unit with just high power output.
The available power source is just as important a factor in your choice. If you’re at a campground with an electrical hookup, check how many amps you’re allowed to use. At many sites, that’s 6 or 10 amps, sometimes more. At 230 volts, 6 amps delivers about 1,380 watts. If you turn on the electric kettle, water heater, and electric heater all at the same time, the fuse could blow. At a site without electricity, gas or a built-in heating system is usually a more practical option, but stricter safety rules apply in those cases.
For many RV and trailer travelers, electric heating is the most comfortable choice at a campground with electricity. A compact ceramic heater warms up quickly and often comes equipped with a thermostat, tip-over protection, and overheat protection. An electric convector heater, on the other hand, provides gentle, even heat and operates quietly. This is pleasant when you’re reading, sleeping, or spending time indoors with your family.
A fan heater is compact and quick to heat, but the audible whooshing sound can be less cozy in a quiet RV. Also, moving warm air dries out the space a bit more. For a quick warm-up in the morning, that’s rarely a problem. If you want to sit comfortably for hours on end, a quieter convector or ceramic heater is often more pleasant.
Gas heating is a good option when you’re off-grid or don’t want to rely on an electrical hookup. Many RVs and travel trailers already have a built-in gas heater designed specifically for the vehicle. This system is generally the safest and most practical gas solution, provided it’s properly maintained and used correctly.
Portable gas heaters require extra caution. Combustion produces moisture, and carbon monoxide can be released if ventilation is insufficient or if there’s a malfunction. Therefore, only use a portable gas heater if the model is explicitly suitable for the intended use, and follow the instructions carefully. Ensure constant ventilation and always use a working carbon monoxide detector in the sleeping and living areas. A portable gas heater is not a wise choice for a small, enclosed tent or a rooftop tent.
A diesel heater is especially popular in motorhomes, camper vans, and some rooftop tent setups. Such a system can provide powerful, dry heat without requiring an electrical outlet. However, purchasing and installing one requires more specialized knowledge. For travelers who often spend the night in the early and late seasons or off-campground, this investment can be particularly comfortable. For a few cool summer evenings, it’s usually more than enough.
Power output is useful, but it’s not the whole story. For a small, reasonably insulated caravan or RV, 500 to 1,000 watts of electric heating is often sufficient as supplemental heating. In cold weather or for a larger space, 1,500 watts can be comfortable, as long as your power connection allows it. Preferably choose a model with multiple heat settings. That way, on a mild evening, you won’t use more energy than necessary and you’ll have more capacity left for other appliances.
It’s harder to estimate the heating capacity for an awning. Tent fabric provides limited insulation, and every time someone walks in or out, heat escapes. An electric heater can mitigate the worst of the cold, but don’t expect a living-room-like atmosphere on a bleak November day. A well-fitting tent rug, side walls, draft stoppers, and a cozy seating area often provide more comfort than just a more powerful heater.
So think in zones. Heat the area where you’re sitting, not necessarily every cubic meter of air. A compact heater near the seating area, combined with warm socks, a cozy throw, and comfortable pillows, makes an evening under the awning surprisingly pleasant. That’s smart kamperen: minimal waste, plenty of atmosphere.
A 1,000-watt heater consumes about 1 kilowatt-hour per hour on the highest setting. If it runs at full power for three hours, that’s 3 kilowatt-hours. In practice, a thermostat often switches down once the desired temperature is reached, so actual consumption may be lower.
Also be mindful of your total power consumption. Plugging a 1,500-watt electric heater, a 2,000-watt kettle, and a hair dryer into the same 6-amp outlet is a recipe for trouble. Spread out the use of high-power appliances throughout the day and temporarily turn the heater down when you’re making coffee or cooking. That way, the evening stays warm without a trip to the circuit breaker panel.
Heat is only cozy if you can relax comfortably while using it. Place an electric heater on a stable, level surface and leave plenty of clear space around it. Do not place it next to curtains, towels, sleeping bags, chair cushions, or the dog’s sleeping area. A heater with tip-over protection and overheat protection isn’t a luxury—it’s a reassuring basic feature.
When using heaters outdoors, only use those explicitly designed for outdoor use. A standard electric heater in a damp awning or under an open canopy is not automatically safe. Check the moisture protection rating, protect plugs and connections from rain, and use a sturdy camping extension cord that’s fully unrolled. A coiled cord can get hot under prolonged use.
Heating at night requires extra caution. Do not leave a portable electric heater running unattended, and do not use a portable gas heater while sleeping. If you need heat at night, use the built-in heating system in your RV or trailer—which is specifically designed for this purpose—and follow the manufacturer’s instructions. A warm sleeping bag, an insulated mat, and, if necessary, an electric blanket suitable for camping use are often a safer and more economical alternative to continuously heating the entire space.
Ventilation remains essential, even when it’s cold outside. A small ventilation grille or a slight opening prevents condensation and keeps the air fresher. Ventilation is absolutely necessary, especially when using gas. Install a carbon monoxide detector according to the manufacturer’s instructions and test it regularly. Such a small device undoubtedly deserves a permanent spot in every caravan, RV, and folding trailer.
The best camping setup isn’t just about the temperature on the thermometer. Arrange your seating area so that warmth also creates a cozy atmosphere: a soft rug underfoot, a throw blanket within reach, and lighting that doesn’t feel cold. In a caravan or camper, it helps to let the sun’s warmth in during the day and close the curtains as soon as the temperature drops. Draft strips, insulated window covers, and a door that seals tightly make your heating noticeably more effective.
For roof tent campers, preparation is especially important. Choose a well-insulated sleeping pad, make sure your bedding stays dry, and prevent wet jackets or shoes from sitting inside and releasing moisture. A compact electric heater at the campsite may be all you need to warm up a bit before bedtime. During the night, high-quality sleeping gear retains heat without any additional risk.
At Camping Cocooning, we believe that practicality and style go hand in hand. A carefully selected heater fits your travel style, takes up minimal valuable space, and enhances that wonderful feeling of coming home to your campsite. So don’t just choose a heater based on specs on paper—choose a solution that lets you enjoy sitting outside or inside just as much on a cool evening.
