The Best RV Heaters for Winter Camping in 2022

If you go winter RV camping on a regular basis, an RV heater is a wise investment.

Of course, most RVs have a built-in furnace, but an electric or propane space heater supplements that heat (or acts as an emergency backup), especially when camping in very cold weather. Or, maybe, you prefer to run a portable heater as your sole way of heating your RV while boondocking.

Whatever your reasoning behind adding a portable heater to your RV camping checklist, know that not all models perform the same. It’s important to buy a heater for your RV that best suits your individual RV camping needs.

Here’s exactly what you need to know to buy the best RV heater for cold weather camping.

Dr. Infrared Portable Space Heater

The Dr. Infrared Portable Space Heater is an efficient RV heater in a stylish package.

This electric heater is unique in that it utilizes infrared heat. Basically, this type of heat warms objects instead of the air surrounding it. Notable about this style of heating is that the heater itself doesn’t get hot or even warm except for the small fan section. Thanks to this and the sturdy design, this is one of the best RV heaters for those with children or pets.

This Dr. Infrared heater is also unique because it comes with a built-in thermostat. Simply put, you’re able to set the heater to keep your RV at a specific temperature. Most other heaters for RVs don’t have this function. This heater produces a maximum 1,500 watts but is fully adjustable for heating at lower temperatures.

Types of RV Heaters

Other than built-in heaters, like RV furnaces, you have two main types of portable models to choose from: electric heaters and propane heaters. Here’s the low-down on each type:

Electric Space Heater

An electric space heater requires electricity from your RV to run. Several types are available, including ceramic heaters, infrared heaters, and oil-filled heaters.

Although electric RV heaters require you to be connected to shore power, run off your battery, or have another power source, they are easy to use and effective. They are great when you’re at an RV park or a campground with electric hookups, but fall somewhat short when it comes to barebones camping, such as boondocking.  

Propane Space Heater

Gas-powered space heaters usually run on propane. These propane RV heaters are quite efficient. In fact, they’re often cheaper to run than electric heaters. The catch is that you need a steady supply of propane to run them.

Other than the need to resupply fuel, the main gripe people have with propane heaters are potential safety issues. However, the best indoor models are quite safe to use, especially when coupled with ventilation (crack a window) and a carbon monoxide detector. Propane RV heaters are typically your best bet if dry camping is your forte.

RV Heater Buyer’s Guide

There isn’t a single RV heater that’s best for everyone. Instead, the best model for you depends on your individual needs and preferences. Here are a few of the most important considerations:

Type of RV

Consider the size and type of RV you own before buying an RV heater. Naturally, a larger RV requires a more powerful heater (unless you only want to heat a closed off space). Also, think about your RV’s pre-installed furnace or heater. For example, some trailers, like pop-up campers, don’t come with any built-in heating source whatsoever.

Expected Weather

RV camping in very cold weather warrants a more robust heater. This is especially true if you’re staying somewhere without shore power. For cold-weather boondocking, a powerful emergency heater is a must. Camping in milder weather, however, might only require a small RV heater with an equally small heat output.

Style of Camping

As mentioned above, a big consideration when buying an RV heater is if you usually camp with or without RV hookups. Having utilities close at hand makes an RV electric heater a more practical choice while many dry campers prefer a fuel-powered portable heater instead.

Comfort Level

How warm do you like it, anyways? If you love to be toasty warm inside your RV, a more powerful heater is a must. If you just want to stave off the chill and are fine throwing on a sweater and wrapping a blanket around your legs, you probably don’t need something quite as powerful.

Your Budget

Quality RV heaters range in price for as little as $25 to well over $100. Not only should you shop for a heater within your budget, but you should make sure that this heater is powerful enough for your needs. Don’t buy a heater just because it’s cheap if it’s not the right model for you!

How to Safely Use an RV Heater

Both propane heaters and electric heaters can be safely used inside your RV. But it’s essential to use them correctly and safely to prevent dangerous accidents. Both types of RV heaters can be dangerous if used incorrectly.

Here are the most important RV heater safety tips:

1.     Buy a Model with Safety Features

The best RV heaters come with built-in safety features. Most important is an automatic tip-over shut-off switch. Other common safety features include a pressure-sensing shut-off switch, oxygen depletion sensor, and high-limit shut-off switch.

2.     Keep Flammable Items Away

Ensure that your heater is well away from flammable objects. Take care not to let the heater touch blankets, clothing, and other hazardous objects, whether your heater is electric or propane.

3.     Place on a Sturdy Surface

Always place your RV heater on a flat, stable surface to reduce the chances of tipping. And, never use your space heater while the vehicle is in motion.

4.     Be Cautious Around Children and Pets

Keep an eye on children and pets while the heater is in use. This limits the possibility that the heater will be knocked over while in use. And, if it is knocked over, you’ll be quicker to place it back upright.

5.     Don’t Use at Night

Personally, I prefer not to use space heaters in my RV overnight. Although many electric and propane models are safe for overnight use, I prefer to use them to heat my space before bedtime then curl up in a warm blanket through the night. Then I turn the heater back on to reheat the space in the morning.

6.     Use Smoke and Carbon Monoxide Detectors

Maintain the smoke detectors and carbon monoxide detectors in your RV. These devices are pivotal to keeping you safe while using an RV heater. Check the batteries and test your detectors regularly.

7.     Never Use a Damaged RV Heater

It’s better to spend a night in the cold than risk a fire. Damaged heaters, especially electric models with frayed cords, are apt to start a fire. Never use a damaged RV heater. Buy a new model or repair the broken device first.

RV Heater Alternatives

A portable space heater is not always the best way to heat an RV in winter. Other effective options include:

Factory Heater

Most RVs come with a factory-installed heater. Depending on the model, this can be an effective way to heat your RV.

• Direct Discharge – Most common in older RVs, this type of RV furnace blows hot air directly from the faceplate.

• Ducted Discharge – Increasingly common on newer RVs, this type of RV furnace blows air through ducts on the walls or ceilings of the RV rather than through the unit itself.  

Many RV furnaces use a combination of electricity and propane to run. You often must be plugged in to utilities hookups to use these effectively.

Of course, it is possible to run your RV furnace for short periods of time while dry camping by relying on your battery system and propane fuel reserves. Another option is to invest in a portable power station (such as a generator) or solar panels for RV camping.

RV Share has an excellent guide on how to replace an RV furnace.

RV Wood Stove

Wood stoves are increasingly popular in RVs and trailers. Despite the fact that they use a wood-burning fire to heat your RV, the newest models are extremely safe. Although installation can be a little tricky, it really doesn’t get much better than listening to a wood stove crackle as your RV stays toasty warm in even the coldest weather. The Kimberly Wood Stove is one of the best wood stoves for RVs and other small spaces.

Electric Blanket

Sure, it’s not actually an RV heater, but an electric blanket is an effective way to stay warm in your RV this winter. Use yours to supplement the heat from your RV furnace or your RV heater on the coldest nights. Of course, regular old blankets, extra layers, and other winter camping hacks will also help you stay warmer.
