Many RVs come equipped with an electric fireplace. When it gets a little too cold when you’re trekking the Alaskan wilderness or whichever trails you choose to explore, all you need to do is switch on the heater. This means that you don’t need to worry about anything other than the running costs.

Unfortunately, not all RVs will afford you this convenience. Indeed, most RVs don’t contain any special heating appliances other than the standard air conditioning.

You need to decide – on your own – if you need a heater in your RV, shop around to identify the best RV heaters, and budget for both the purchase and installation before you mention running costs.

Since this shopping process can be incredibly challenging, especially if it’s your first RV or you’ve never shopped for RV heaters before, we’ve designed this guide to make your work a little easier.

Read on to learn what you need to know about boondocking heaters, their benefits, and how they work. We’ll also discuss RV heater safety and convenience features.

RV Heater Buying Guide

Boondocking, also known as dry camping, wild camping, or dispersed camping, is a great way to spend your holidays.

This kind of camping involves staying in the wilderness without hookups or designated companies – an excellent idea for RV enthusiasts looking for tranquility, isolation, and a reconnection with nature. Although it has its difficulties, you can have the time of your life.

Before we begin discussing heaters for boondocking, maybe we should also mention that the activity is illegal in some parks, though most parks allow it. National parks and wildlife refuges are two of the best places to take your boondocking.

Also, some boondocking locations may have electricity, while others may not offer such convenience. If you’d like to have an electricity connection during your camp, maybe for reading or cooking, make sure to locate a destination with electricity.

Above all, all boondockers need heating. Even in the summer heat, temperatures at night can drop below the dew point, leaving you and your crew (if you decide to bring a friend or two) shivering.

A heating solution, such as a portable space heater, would be invaluable in such circumstances. As already mentioned, some RVs arrive with built-in heaters while others don’t. If your RV has none, you’ll need a primary heat source.

You may also need a supplementary heater if the built-in heating system isn’t sufficient.

Types of RV Heaters

Pretty much all RV heaters run on electricity or propane, though you may find a few models that operate on special oils and even kerosene.

Some people also choose to bring wood stoves to camps, though most parks don’t allow it. Natural gas lines may not be readily available at the destination, so it’s not usually a practical option.

Before we look at the various RV heater design styles to consider, the following is comparing electric vs. propane heaters to help you make an informed choice.

Electric RV Heater Pros and Cons

Electric heaters are currently the most popular types of heaters. The reason is that these heaters are pretty much maintenance-free. There’s no cleaning, changing fuel, fetching wood, or dealing with ashes.

They also offer instant heat – no waiting. Within a minute or two of switching on the heater, your RV or tent will be warm enough to keep you comfortable.

Additionally, electric heaters;

  • Electric heaters are generally inexpensive
  • The heaters don’t generate a lot of noise
  • You don’t need to carry extra fuel to the camp
  • Electric heaters have a very long lifespan

On the flip side, however, electric heaters require electric power availability; otherwise, they become useless. This may create a challenge as not all camping destinations have electricity connectivity. Besides;

  • Power outages can be a considerable inconvenience
  • The heaters get very hot, thus pose a burn risk

Propane RV Heater Pros and Cons

The biggest advantage of gas heaters is its high heat capacities. You can’t compare gas and electric heaters in terms of heat output – gas models produce way more heat.

This can be even more important when you’re going camping in a poorly insulated RV or intend to sleep in tents. You’ll need plenty of power to keep you warm through to morning.

Additionally;

  • Propane heaters don’t need electricity to run
  • Less expensive to run (30% more cost-effective)
  • Incredible flexibility – you can take them anywhere
  • Power blackouts are no longer a problem

Unfortunately, propane heaters come with a few drawbacks that you also need to keep in mind. For one, propane heaters are inherently unsafe in closed spaces. Since combustion gases are vented in the room, they create the risk of carbon monoxide, a poisonous gas. Also;

  • Propane heaters are more expensive upfront
  • You need to bring a few tanks of gas on your trip

Types by Design/Style

In addition to fuel considerations, RV heaters also come in a variety of styles and designs. The following are some of the most popular options;

Forced-Air Furnaces

Forced air furnaces are permanently installed in the RV. They comprise four main parts a heat source, thermostat, blower motor, and ductwork.

In electric heaters, the heat source is a high-resistance heating element that becomes very hot when current is passed through it. The blower motor has two essential functions. First, it blows cold air into the heating system. Secondly, it forces hot/warm air into the ductwork and the room.

The main advantage of forced-air heaters is excellent heat distribution. No heater can distribute heat as effectively as forced-air heaters. However, the heaters tend to make a bit of noise and are the most maintenance-intensive on this list because of the fan system. Forced air systems can also use propane gas. 

Electric Heat Pumps

Electric heat pumps are heaters that are built into an air conditioning system. Think of them as mini-splits. They don’t create heat. Instead, they extract heat from one location and dumps it in a second location.

In the RV case, for instance, the heat pump will remove heat from the outside and dump it in the RV. The units can also work in reverse when it gets too hot in the RV. In this case, they’ll extract heat from the RV and dump it outside.

Heat pumps are considered the most energy-efficient heaters because they don’t require heating a high-resistance wire or burning fuel. They are also valuable because they double up as air conditioning units.

The only downside is that they don’t generate enough heat. Thus they can’t work as primary heaters. Also, they only run on electricity.

Electric Space Heaters

Electric space heaters are an excellent heating solution for small spaces, such as the RV – if you have access to electricity. They work by heating a high resistance wire, which gives off heat.

The heat is then dispersed throughout the space. Many models are radiant heaters that don’t need fans, though a few use small fans to distribute the heat. Installation options vary. Some are portable, while others permanently screw onto or recess into the RV wall.

The biggest attraction of this type of heater is flexibility. When you buy a portable electric space heater, you can use it in the bedroom, kitchen, basement, and many other places without any trouble.

However, they require electricity and would be of no help if you’re going camping in an area without an electricity connection.

Gas Stoves and Fireplaces

Gas stoves and fireplaces are an excellent choice if you desire a decorative focal point in the RV. The stoves pump out a lot of heat. Many are rated at 40,000 BTU or higher, which is enough for every corner of the RV.

The fireplaces may not give off as much heat, but they offer an ambiance that cannot be matched by any other product on this list.

A key attraction for people who love these units is the convenient controls. In both cases, control is primarily via remote devices.

Most gas stoves and heaters also feature timers that allow you to program the heating. A significant downside, however, is the need to bring along enough gas supply. Also, don’t forget about the inherent safety risks.  

Hydronic Heat Systems

Finally, hydronic RV heaters are also relatively popular among campers and motorhome owners. One company that makes some of the best products in this category is AquaHot, formerly HydroHot.

These systems replace both the heating system and the hot water system. They use a diesel-fired boiler to provide heat as well as on-demand hot water.

The way the process works isn’t very complicated. The hydronic system features a heat exchanger filled with antifreeze. As the heat exchanger is heated, the antifreeze circulates to a series of small radiators.

Each radiator features a small blower fan that provides forced-air heat. These units are incredibly economical. But, they also require a significant initial investment.

Things to Consider When Choosing the Best RV Heater for Boondocking

We’ve already mentioned fuel and heater type. They are the first two things you need to consider when shopping for an RV heater for boondocking. Four other factors to consider are as follows;

Heating Capacity

RV heater capacities are measured in British Thermal Units (for gas and oil models) and kilowatt-hours for electric models. The number of BTUs or kilowatts you need for your RV will depend on several factors, including the RV size, insulation quality, and where you’re headed (the destination).

However, the standard requirement is 25-35 BTU per square foot in warmer climates and 45-60 BTU per-square-foot for colder climates. Don’t forget to insulate your RR as best as you can to prevent extensive heat losses.

Storage and Portability

As we’ve repeatedly mentioned, some RV heaters are permanently installed. These models don’t create any further storage concerns.

However, the majority of RVers use portable heaters primarily or as supplemental heat sources. Where will the heater sit? What about when you’re not using it? Where do you store it?

These are some of the things you need to ask yourself from the onset to avoid disappointments later on. A large gas heater needs significant storage space. Does your RV have that space? If not, consider smaller electric models that can be packed into a bag.

Durability/Endurance

Camping isn’t the same as home use. There’ll be a lot of bumps and rough riding. You may also need to move the heater a lot during the short trip between storage and use points.

And, if it’s a gas heater, you’ll be taking it out of the RV at least twice every day for refilling. Can the heaters you’re considering withstand such rough handling? Or, would they break apart at the first bump?

Something else to consider here is the warranty. If the RV heater breaks easily, a few manufacturers may be willing to pay for the repairs or replace the unit. Otherwise, you risk losing all your money before you get to the destination.

Affordability

Finally, all great RV heaters are worth the price. It doesn’t have to be dirt cheap. However, it also makes no sense buying an RV heater for thousands of dollars if you’re not an avid RVer.

If you’re only buying it for single-use, a modest electric model you can also use at home would be a more worthwhile investment. Alternatively, consider a portable propane model that you can later use in the garage.

However, for enthusiasts that go on boondocking camps a few times every year, you should be willing to spend more on something more suitable for the rough roads.

In this case, spending several hundred on a heater makes perfect sense. In both cases, though, the price should be within your budget.

How to Winterize Your RV

If you won’t be using the RV during the winter, it’s essential to winterize it to prevent damage. Consider the following winterizing tips;

  • Drain the water and dry the water lines: Flush the water from the freshwater holding tank, black holding tank, and gray holding tank.
  • Add antifreeze to the plumbing: You can do this by adding a water conversion kit or from the outside using a hand pump. Turn on the water pump to pressurize the system.
  • Thoroughly clean the RV: Take everything off the refrigerator and clean it thoroughly. Don’t forget to clean the cupboards and drawers too.
  • Cover any vents and holes: These include the vent pipes, roof vents, exhaust pipes, and fan vents. Don’t forget to remove the covering material when the RV comes out of storage.
  • Prevent rodents and pests: Since the RV will stay unattended for months, rodents can turn it into their home. Covering any vents and holes (#4), putting out mot ball, and setting traps can help.
  • Fill or remove the propane tank: The containers should be topped off before storage as it helps them better withstand the weather. As for removable tanks, take them off and store them in an area outside the RV.
  • Charge the battery: Fully recharge the battery and top off the water levels before storage. However, if the weather is too cold, consider removing it and storing it in a warmer place, outside the RV.
  • Top off gasoline and diesel tanks: This helps preserve the RV engine. Consider adding a fuel stabilizer from the RV supply shop. Also, top off the brake fluid and other oils as necessary.
  • Cover the RV: You can use a tarp to keep away dust and grime. However, more breathable material is preferable as it helps prevent mold and mildew that may be trapped under the cover.

RV Space Heater Safety

Whether you’re using an electric, propane, or oil heater in the RV (avoid wood stoves altogether), safety is paramount. You don’t want to create preventable safety risks during your camping trip. Consider the following;

  • Choose the right heater: RV heating safety starts with finding the right heater. Is it a safe heater? Is it rated for RV heating? Does it have safety features such as overheating protection and an anti-tip-over switch? These are just some of the questions you need to ask.
  • Ensure a safe distance: This applies to all heater types. You need to position the heater at least three feet away from yourself and flammable items such as furniture or curtains. If you decide to sleep with the heater, ensure that it’s placed at least a meter away. Never sleep with a propane heater.
  • Ensure sufficient ventilation: This especially applies to propane heaters. Since there’s a risk of carbon monoxide poisoning, always open the windows when heating. Early signs of carbon monoxide include dizziness, headaches, and nausea.
  • Use a carbon monoxide sensor: An oxygen depletion sensor (ODS) is the one people with gas heaters buy. It tracks oxygen levels in the area and sounds an alarm if the levels become dangerously low.

Wrap Up

RV boondocking can be an exhilarating experience. The solitude provides the perfect opportunity for reflection or self-finding.

It also offers an excellent opportunity for bonding with a friend or loved one. But, you’ll need some heating on your trip, which means you may have to go shopping for an RV heater.

Make sure to find the right-size heater as it gets freezing out there. It should be powerful enough, easy to handle, and safe enough for the trip. You also want a model that doesn’t require a lot of maintenance. Happy boondocking!
