Space heaters are an essential accessory for RV owners, providing a reliable heat source that can make traveling and living in your vehicle comfortable during the colder months. Unlike the central heating systems that come built into many RVs, portable space heaters give you the flexibility to add warmth exactly where and when you need it. They are often more energy-efficient than running the RV's furnace, especially if you're looking to heat a particular area of your RV rather than the entire space.

When selecting the best RV space heater, it's important to consider safety features like automatic shut-off, tip-over protection, and a cool-to-the-touch exterior. Since space is at a premium in RVs, the size and portability of the heater are also crucial factors. Furthermore, you'll want to think about power consumption, as it will need to be compatible with your RV's electrical system to avoid overloads.

The market offers a variety of heater types, such as electric ceramic heaters, infrared heaters, and propane heaters, each with their own set of pros and cons. Electric heaters are typically the easiest to use, requiring only an outlet to start making your space cozy. Infrared heaters are effective at directly warming people and objects without heating the air, thus being more energy-efficient. Propane heaters, while handy in areas without electricity, require proper ventilation to prevent a buildup of harmful gases.

We've researched various models and assessed them based on their heating capabilities, energy efficiency, safety features, and usability to ensure you can find the right space heater for your mobile abode. Whether you're looking for something to take the chill off during a brisk morning or want to keep your living space toasty throughout a cold night, we have the options that meet a range of needs. Now let's take a closer look at the top performers that can help maintain a comfortable temperature in your RV.

  • Dual heat settings and a fan mode accommodate year-round comfort
  • Comprehensive safety systems prevent overheating and accidents
  • Its compact design with a carry handle enhances portability and ease of placement


  • The heat coverage area might be limited in larger RV spaces
  • No battery operation, reliant on a power outlet

During our chilly winter road trips, we've come to appreciate the swift warmth our GiveBest Compact Heater offers. Its ceramic heating technology is not only efficient but also quiet, maintaining a peaceful environment after hours on the road. With this heater, the cold doesn't stand a chance, especially in confined spaces - perfect for cozy evenings in our RV.

Safety is never a concern with this heater. We've accidentally knocked it over a time or two, but its tip-over protection system instantly shuts it off, preventing any mishaps. Similarly, if it starts to overheat, it'll power down on its own—we've tested and appreciated this feature.

The GiveBest Compact Heater's portability meant we could easily move it from the dining area to the sleeping quarters with minimal effort. Given its small footprint, finding a spot for it was never an issue; it snugly fits almost anywhere. Despite its size, when we turned it on, the 1500W setting heats the space so quickly that we're comfortable within minutes.

Comparing the GiveBest with other heaters on the market, here are some standout points:

Feature GiveBest Compact Heater Other RV Space Heaters
Heating Technology PTC Ceramic Heating Tech Variable (Ceramic, Infrared, etc.)

The one trade-off to consider is the coverage area—the GiveBest model is ideal for smaller, targeted areas, whereas larger RVs may need a model designed for more extensive spaces. However, this heater's efficient heating and safety features stand out for us, making it a reliable choice for our travel needs.

Dr. Infrared Heater Portable Space Heater

With its quick heating ability and whisper-quiet operation, this Dr. Infrared heater is a must-have to stay cozy in your RV during chilly travels.


  • Provides substantial warmth rapidly, enhancing comfort quickly
  • The unit runs quietly, allowing for an undisturbed environment
  • Includes a remote control for convenient temperature adjustments from afar


  • The heater may struggle to warm very spacious areas efficiently

Our friends who have larger RVs mentioned it took a bit more time to feel the entirety of its effects in their spacious living quarters.

This did come with a minor trade-off with the noise it produced, noticeable but not deal-breaking for us given the cozy warmth it maintained.

Using the adjustable thermostat, we easily found a comfortable heat level for sustained periods. While the Kismile heater excelled in small quarters, it did struggle to challenge the brisk air in more expansive sections of our living space.

Buying Guide

Heating Capacity

Key to choosing the right RV space heater is understanding the size of your RV and the amount of space you need to heat. We measure heating capacity in watts or British Thermal Units (BTU). Here's a basic guide:

Area Size Suggested Wattage
Small (up to 100 sq. ft.) 750 W
Medium (100-250 sq. ft.) 1,500 W
Large (250+ sq. ft.) 2,000 W +

Safety Features

Safety is paramount when selecting a heater for a confined space like an RV. Look for these crucial features:

  • Tip-Over Switch: Shuts off the heater if it's knocked over.
  • Overheat Protection: Cuts power if the heater gets too hot.

Power Consumption

We must consider energy efficiency to maintain battery life in RVs. Look for heaters with adjustable thermostats or low power modes to conserve energy.

Heater Type

There are different types of heaters, and each has its benefits:

  • Ceramic Heaters: Quick heating, typically with oscillation for even distribution.
  • Infrared Heaters: Efficient, directly heating objects and people, not just the air.

Noise Level

For a peaceful environment, especially at night, select a heater with a low noise level. Quieter models will have a decibel rating below 50 dB.


Heaters with handles or wheels are easier to move around, so they can be adjusted as needed for optimal heating.

Remember, the best RV space heater is the one that fits our specific needs, offers the most safety features, and provides a balance between heating capacity and energy efficiency.
