Space Heaters for Campers: Are They Safe?

If you love RVing year-round like Susan and I do, you’ve probably discovered that staying warm in cold weather takes a little creativity. One of our favorite tools for taking the chill off—especially during frosty mornings or brisk fall nights—is a good space heater.

When used properly, space heaters for campers are absolutely safe and can really help supplement your RV furnace, saving propane and keeping your rig cozy without all that furnace noise.

In this post, I’ll share my personal experience using space heaters in our RVs, explain the different types available, and recommend a few of my favorite models that work great for campers.

Why I Use a Space Heater in Our RV

Even though our motorhome is a four-season rig, the furnace is what heats the underbelly and keeps the plumbing from freezing. So when we’re camping below freezing, I always run the furnace at least part-time to protect the pipes—but I’ll use space heaters to maintain comfort inside the coach.

The big benefit is cutting down on propane use. A 30,000 BTU furnace burns about a gallon of propane every three hours! That means a single 20-pound tank might last only 3 to 7 days while boondocking—and remember, you still need propane for the fridge, stove, and water heater.

A space heater helps reduce how often the furnace kicks on, which means less propane, less noise, and more consistent warmth.

5 Main Types of Space Heaters for Campers

After years on the road, I’ve tried just about every type of space heater you can buy for an RV. Each one has its advantages and disadvantages, depending on your camping style.

1. Ceramic Space Heaters

Ceramic heaters use heated metal coils surrounded by ceramic plates. They’re efficient, heat up fast, and are great for small RV spaces. They’re also pretty affordable—usually the least expensive type you’ll find.

I use a small ceramic heater in the morning to take the chill out of the air while I make coffee. It works quickly, but they do draw a fair amount of electricity, so be mindful if you’re on 30-amp service.

2. Infrared Space Heaters

Infrared heaters create radiant heat—like the warmth from the sun on your face. They’re quieter since there’s no fan, and they use less electricity for the same amount of heat. They’re a bit pricier (starting around $150), but they’re efficient and low maintenance. Some are wall-mounted, which is nice if you don’t have much floor space.

3. Micathermic Space Heaters

These heaters combine radiant and convection heat using thin mica panels. They warm up fast—usually in under a minute—and are lightweight and quiet. We used one in our Class C RV for a while, and it was great for small spaces. The only downside is the surface can get hot, so I wouldn’t recommend it if you have kids or pets.

4. Oil-Filled Space Heaters

Oil-filled heaters use an electric element to heat oil sealed inside the unit. They take longer (about 20–30 minutes) to warm up but hold heat really well and maintain an even temperature.

I like using ours at night because it’s completely silent and safe to run while we sleep. The oil never needs to be replaced, and most units have built-in tip-over and overheat protection.

5. Propane Space Heaters

Propane heaters are a solid option if you’re boondocking without hookups, but you must provide ventilation. Crack a window or open a vent and make sure your heater has a low-oxygen sensor and automatic shut-off feature.

We used a Mr. Heater Big Buddy during a winter stay in Colorado—it kept our rig warm and cozy, but I never leave it running overnight or unattended.

My Favorite Space Heaters for Campers

Here are some great space heaters that I’ve either used personally or seen work well in RVs.

1. Lasko Ceramic Tower Heater

This 1,500-watt heater is simple, affordable, and effective. It has two heat settings, an auto thermostat, and a remote. We’ve used this one for years—perfect for taking the edge off on chilly mornings.

2. Dr. Infrared Heater

I love this one for full-time RV living. It combines infrared heat with a built-in humidifier, so you don’t dry out your air in winter. It’s also energy-efficient and quiet.

3. Pelonis Oil-Filled Heater

This heater is whisper-quiet and great for overnight use. It has three heating modes, a programmable thermostat, and safety features like tip-over protection.

4. DeLonghi Mica Panel Heater

If you’re short on space, this slim, wall-mountable heater is a great choice. It’s lightweight, allergy-friendly (no fan to stir up dust), and has a thermal shutoff for safety.

5. Mr. Heater Big Buddy Propane Heater

If you boondock often, this is the one to get. It heats up to 450 square feet and has built-in safety sensors. You can use one-pound canisters or hook it to a larger tank for longer stays.

Are Space Heaters Safe to Use in an RV?

Yes—as long as you use them correctly. Always choose heaters with tip-over and overheat shutoff sensors, and never leave them unattended. Keep them away from curtains, bedding, and anything flammable.

Use outlets rated for the heater’s wattage, and don’t run them through cheap extension cords. When we camp in cold weather, I often set one space heater in the main living area and another near the plumbing—especially if temps drop below freezing.

Just opening the cabinet doors under the sinks lets the warm air flow around the pipes.

What to Look for in a Safe RV Space Heater

When shopping, check that your heater is approved by a Nationally Recognized Testing Laboratory (NRTL) such as UL (Underwriters Laboratory) or ETL.

Look for these safety features: tip-over shutoff, overheat protection, thermostat control, multiple heat settings, and a cool-touch exterior if you have kids or pets. Wall-mounted or counter-top units are also great for keeping heaters out of the way.

How Long Can You Run a Space Heater in Your Camper?

You can safely run a space heater as long as the manufacturer allows. We typically run our oil heater all night on cold nights without any issue. If you’re nervous about sleeping with one on, try running it for a few hours before bed to pre-warm the rig, then switch to your furnace or electric blanket overnight.

Final Thoughts on Using Space Heaters for Campers

Space heaters are a safe and efficient way to stay warm in your RV and reduce propane use. Even in the Southwest, we’ve had nights that dip into the 30s—perfect for firing up a space heater.

They’re quieter than most furnaces, safer than people think, and a must-have if you camp in cold weather. Just remember the basics: use models with tip-over and shutoff features, keep them away from anything flammable, and give them space to breathe. Used wisely, a space heater can make your RV adventures more comfortable all year long.
