5 Best RV Trailer Space Heaters You Need To Try!

The best  RV Space Heaters

There are several reasons why you might want to consider investing in a trailer space heater for your RV.

For one, many people find them much more efficient than portable air conditioners and other heating products. Also, unlike mobile homes and some RVs, most Class A and Class C motorhomes come with forced air furnaces that operate year round—most notably in the winter time when there is no need for them.

This means that any heat directed to those furnaces is simply lost unless it’s used somehow.

The best 5 RV Trailer Space Heaters

There are several types of space heaters – here are a few of the best heaters for travel trailers and motor homes.

1. Lasko Ceramic Adjustable Thermostat Space Heater

This Black Tower model is capable of heating up spaces that are about 500 square feet or more. It measures about 22 x 7 x 46 inches (LXWXH) and weighs a little over 30 pounds which isn’t too bad, but it’s definitely not as compact as the previous model in terms of design.

However, this model does require less assembly at around 5 minutes or so. This unit features 3 adjustable settings for heat along with a fan speed function that’ll let you customize your desired level of comfort within any given space.

There’s also a child safety lock available which prevents children from playing with the heater when you’re away–which is especially ideal for families with young kids running around during holidays like Christmas time or Thanksgiving where they tend to be very curious about everything!



  • Efficient and reliable overall
  • Cheap


  • Element gets quite hot

2.) Mr. Heater 30,000 BTU

If you don’t want to plunk down a lot of cash for an expensive RV trailer space heater, this one could be just what the doctor ordered.

It’s been proven by many customers that this product is a great value for the price and will accomplish all the necessary things you need it to while on the road.

This Mr. Heater model comes in both liquid propane and natural gas options. The liquid propane version works off of 1 pound disposable propane bottles, while the natural gas option runs off your existing LP line so as long as you have a threaded fitting available that connects to your hose, it should work without issue.

No matter which option you choose, most people find them pretty easy-to-use and get them set up in only a few minutes.


One of the biggest advantages this model has is that it’s really compact, so you don’t have to worry about taking up much space at all. You can easily use it on any size RV or camper coach without taking up extra room since its dimensions are about 15″ x 13″ x 8″.

However, despite its small size, this product will still put out some heat depending on how cold your particular atmosphere is.

It operates with 2200 BTUs per hour which may not be enough for those looking to warm their entire campsite while they’re out exploring the wilds of nature during frigid winter nights—but it should hopefully do just fine as an auxiliary source of heat for an RV trailer.


The Mr Heater MH3B requires a lightweight assembly before you can use it.

As mentioned earlier, this is best used as a supplementary accessory and might not be suitable for your entire heating needs—so if you’re looking to keep everything nice and warm throughout the night in temperatures that dip below freezing, then this isn’t going to work nearly as well unless you have another space heater running alongside it.

The good news is that this model comes with several safety features such as low oxygen sensor shut offs (a huge plus) to protect your family from carbon monoxide poisoning, which is one of the biggest concerns when using these devices inside closed quarters.

It also has an automatic shut-off function that activates when it runs out of fuel. This makes it a very secure heater that you can use for your RV without much worry at all.



  • Lightweight and easy-to-setup
  • Affordable
  • Runs quieter than most others


  • Pretty small

3. Dr Infrared Heater Portable Space

One particular option to consider is Dr Infrared Heater DRST80F Portable Space Heater which has a nice looking design and not much bigger than a coffee can.

The heating power on this model is 12000 BTU with fully adjustable thermostat control that lets you choose your desired temperature from 65-90 degrees Fahrenheit.

It’s ETL approved so it should be safe enough for indoor use without having to worry about damaging anything around it. I personally used this in my bedroom while trying to save electricity bills during winter nights as well as using in my RV lifestyle trailer when needed, and it works like a charm.



  • Adjustable thermostat
  • Suitable for indoor
  • 12000 BTUs
  • LCD screen


  • Price

4.) Mr. Heater F232000 MH9BX Buddy Propane Heater

This propane heater can be used indoors or out. Inside, it can heat spaces of up to 225 sq feet and is nearly 100% efficient. It features an auto shut-off if it’s tipped over, if the pilot light goes out, or if it detects low oxygen levels. Be aware that if you’re operating this heater over 7,000 feet above sea level it may shut off.


5.) Caframo Limited True North Space Heater

This compact little heater is perfect for smaller travel trailers or pop-ups, or even for a tent. It’s just over five pounds, making it easy to carry. It has an anti-freeze setting and a built-in thermostat and promises to be whisper quiet.


RV Trailer Space Heater Types

You can choose either a gas or electric space heater for your RV Trailer. Here are the pros and cons of each:

Gas Heaters

Gas heaters are more efficient and tend to be cheaper than electric space heaters. They run off of propane, which means you’ll have to keep track of your propane supply and allot extra room for those fuel canisters.

They aren’t as reliable at 7,000 feet above sea level or higher, so if you’re camping in the mountains, you’ll want to take that into consideration. However, if you’re camping off-grid or want to conserve electricity, they are a good option.

Electric Heaters

Electric heaters may be the best space heater for your RVTrailer in some cases. You don’t need to worry about toting along propane, and at higher elevations they work better.

You do want to pay attention to where you plug in your electric heater, and be sure your outlet can handle it without overloading.

If you’re going to use an electric space heater for your RV, it’s a good idea to have your outlets, breakers, and wiring in your motorhome checked out to make sure they can handle a space heater. A qualified electrician can help you with this and with any adjustments you need to make.

Ceramic Fan-Forced Heaters are one of the most popular electric space heaters. They are safe around children and pets because the outside stays cool even while they give off heat.

Some come with oscillation options, to disperse heat around the room, or with timers and even remote controls. Some also come with temperature controls, so you can set your heat to a specific temperature instead of just turning the heater on and off.

RV Trailer Space Heater Safety

According to the National Fire Protection Association, always follow these safety tips when you purchase and run your space heater.

  1. Purchase a heater with the seal of a qualified testing laboratory
  2. Keep the heater at least 3 feet away from anything that can burn, including people
  3. Choose a heater with a thermostat and overheat protection
  4. Place the heater on a solid, flat surface
  5. Make sure your heater has an auto shut-off to turn the heater off if it tips over
  6. Keep space heaters out of the way of foot traffic
  7. Never block an exit
  8. Keep children away from the space heater
  9. Plug the heater directly into the wall outlet. Never use an extension cord
  10. Space heaters should be turned off and unplugged when you leave the room or go to bed

RV Trailer Space Heater FAQs

How do I choose the RV Trailer space heater that’s the right size for me?

Selecting the correct size of RV Trailer space heater(s) is an important step in ensuring that your heaters will provide the necessary heating for you and your family as well as operate safely.

The sizing chart below is designed to help you choose the right-size RV Trailer warm air furnace. Keep in mind that these are just guidelines and should not be relied upon exclusively.

Factors like propane supply line construction, ambient temperature, duct length and tightness of installation all play a role in determining how much heat gets delivered to the space being heated.

Note that this table lists maximum BTU output per hour at various fuel pressures. In other words, if you are only using a portion of the available BTU capacity, then should use a lower pressure regulator or ball valve.

What should I consider when buying a RV Trailer space heater?

When buying a space heater for RVing, you should consider the safety features of the unit that are available. Some heaters have auto shut offs or extra safety features like tip over sensors that can help reduce the risk of fire and burns.

You will also want to look into how long the cord is on the heater itself because you may be required to move it from time to time while your camper trailer or RV is in storage, which means you won’t be able to use it if you don’t have enough cord length when you need it most.

You also want to find out what type of fuel is used with a propane powered heater so that you know if there will be an expense associated with having it refilled.

The type of heat you are looking for may also be something that you should consider when shopping for an electric RV trailer space heater.

If you like the idea of an infrared heating system, you will want to make sure that there is a model available that offers this type technology. You should also look into what kind of material the heater is made from because some materials can give off harmful fumes over time.

A nice metal housing can help prevent the release of fumes and lead to a healthier environment in your camper trailer or RV.
