Heat Output

How much heat a heater can generate is, of course, the first thing to look at. If you tend to camp in places with low temperatures (even before nighttime comes), it’s better to get a heater with high BTUs. If not, then the usual range of BTUs might be enough.

Heat Options

Are there heat options? Because you won’t always want maximum heat in your space. Portable heaters for campers are better when you can adjust the heat settings or they have low/high heat options.

Safety Features

Safety always comes first. For the heaters we list below, the power sources are either electric RV heaters or propane gas heaters. 

With the advancement of technology and the process of manufacturing products like these, safety is not really much to worry about. But taking the extra step to be safer by buying space heaters for RV camping with safety features can still give you additional peace of mind.

Power Source

Personally, we think that electric heaters work best for RV heating, while propane gas heater are better for boondocking or dry camping. You might also have your own preference for this one, so remember to check the power source for the heater you want.

Run time

Yes, the heat output can be really high, but how long will it last? Keep this in mind as you decide what will work best for you.


What we can’t forget in this list is the price. This is especially important if you are trying to stay within budget. Some RV space heaters are really great but tend to be on the more expensive side. 

Don’t worry, we’ll help you find the best RV space heater within your budget. Because we found budget-friendly, yet powerful heaters to be discussed in detail later.

  1. This RV heater from Handy works really well for the camper. I bought it to plugin but my plug was a little low in my teardrop so I decided to mount it up a bit higher and use a 3 foot 10amp ( 16 GA) extension cord. I tested the unit and it pulls under 4 amps on high speed then drops to under 1 amp when only the fan is blowing. The controls are easy to use. My camper is only 15X7 and it heats it up very quickly. The heater is very lightweight. The unit pulls airflow from the bottom thus it is designed to plug directly into the wall. Also, the plugin the back rotates in case your outlet is upside down or sideways, the heater could still be positioned vertically.
