  • Heats up to 300 square feet.
  • 1500 watt ceramic heating element.

Dr Infrared Heater DR968

rv space heater reviewsIf you’re looking for an infrared heater for your RV, we recommend checking out the Dr Infrared Heater DR968. It’s a heater for a higher budget. However, for the higher price, it has a lot to offer, including efficient heating and plenty of adjustable settings. This is also a powerful unit that can easily heat up spaces over 200 square feet in size. So you can use it even in a Class A RV.

This RV space heater uses radiant heat technology. It’s equipped with a dual heating system that consists of one quartz infrared element and one PTC element. This system produces more heat and faster compared to other 1,500 watt heaters.

Radiant heating also works by warming up the objects in a room, instead of air. This provides even heat distribution with no loss in heat transfer. Moreover, the produced heat feels more comfortable as it feels like you’re getting warmth from the sun.

Infrared heating also has another advantage. It offers whisper quiet operation with a maximum noise level of 39 dB, which is quiet enough for undisturbed sleep. The heater does have a blower. However, it’s a large 7 inch blower that allows moving large volumes of air at lower speeds. So you wouldn’t have to run it at its highest setting in a small RV bedroom.

There are different settings that you can select to get the perfect temperature in your RV. There are three pre-set settings. They include low, high, and eco modes. The eco mode offers automatic operation for keeping a stable temperature level in a room. There’s a thermostat that allows you to choose a temperature between 50 to 86 degrees Fahrenheit. When it reaches the temperature you set, the heater goes into standby mode. And if the air starts cooling again, the heater turns back on and continues to cycle on and off in this manner.

This highly efficient RV space heater also comes with a remote control. This allows you to control the settings from anywhere in the room. With the remote, you can also set up a timer if you want the heater to automatically shut off.

The heater is also safe for use around children and pets. It doesn’t have any exposed heating elements and the housing might only get warm to the tough, but not hot. This means that animals and children will not get burned if they touch the heater. Moreover, similarly to other heaters, this infrared model also has tip over and overheating protection.

As for the weight, at 19 pounds, it’s one of the heavier RV space heaters on our list. So moving it from room to room will not be as easy as just picking it up by the handle and carrying it away. However, it does come equipped with wheels, so you can easily wheel it around to wherever you need warmth.


  • Comforting radiant heat.
  • Can heat up spaces over 200 square feet.
  • Dual heating system.
  • Maximum 1,500 watts.
  • Thermostat with 50-85F range.
  • 39dB noise level.
  • Includes remote control.
  • Programmable timer up to 12 hours.
  • Expensive.
  • Might be too bulky for smaller RVs.

One of the advantages of this small RV heater is that it can also work to cool the air. It has a setting with just fan operation, which can provide you with some cool air on hot summer days.

This heater can be used in a bedroom or leaving room. Even the highest setting produces no more than 45 dB sound. So while it’s not whisper quiet, you could still use it in your bedroom with a lower setting.

This heater is perfect for heating up spaces that are under 200 square feet. So it’s definitely powerful for such a small unit. It produces enough heat to warm up the space of even larger recreational vehicles.

As for safety features, it includes an automatic shutoff if you tip the heater over or if it starts overheating. On top of that, the heater is made of flame retardant materials, which helps prevent fire hazards. These well designed features will keep your RV safe during the heater’s operation.

This space heater is also conveniently portable. It weighs just 2.2 pounds, so it’s easy to pick up and move to another location. Moreover, it’s equipped with a handle, which makes it even easier to lift it and move it to any room you want.

What Is an RV Heater And How Does It Work?

An RV heater is a special heating device that is designed to keep you comfortable and warm in the confines of your RV. Typically, these are small compact units that are meant to take up minimal space and to heat up the specific room you’re staying in. They feature a portable design, which makes it easy to move it from one space to another depending on where you need more heat at any particular moment.

Mostly, these heaters are either electric or propane. Electric RV heaters offer the advantage of more convenience since they eliminate the hassle of dealing with propane tanks. And propane heaters are better for situations when you don’t want the heater to be draining your RV battery.

Depending on the type of heater, it will have a different concept of how it works to warm up space. For example, ceramic space heaters feature a ceramic element and a fan that heat up the air and then evenly distribute it throughout the room. And radiant heaters warm up the surrounding objects, which in turn, emit the warmth into the air.

Benefits of an Electric RV Heater

Adding a space heater to your RV gear has a whole host of advantages. And here are some of the key benefits:

  1. Make your living space more comfortable. The most important benefit of an RV heater is, of course, to keep you warm in the cold winter months. In many cases, a travel trailer’s built-in heating system is not enough to get sufficient heating. That’s when an electric space heater can make all the difference. It can provide fast and sufficient heating throughout the vehicle.
  2. Heating up different rooms of the RV. One of the benefits of an RV space heater is its portability. Since they’re so light and small, you can easily move them around your RV and stay close to its warmth. Moreover, when you’re not using your RV, you could also easily take the heater with you and use it at your home or office.
  3. Protect your RV. Low temperatures can be damaging to an RV and its parts. And to prevent that, it’s important to invest in a good RV space heater.
  4. Energy saving. A built-in RV furnace heats up the entire space of an RV, while a space heater heats up just one separate room. As a result, a space heater uses a lot less energy than a built-in furnace, which is a good way to save up on energy costs.

Buying Guide For Choosing the Best RV Space Heater

When looking to buy a new RV space heater, there are certain factors that you should take into account in order to choose a unit that is right for you. Since we all have different needs, a heater that is right for you might not be so perfect for another person. That’s why here are a few key aspects to keep in mind when choosing a good RV heater. These aspects will help you determine what is the best electric heater for an RV for your specific needs.

1. Types of RV Space Heaters

Before starting the shopping process for a new RV heater, it can be helpful to understand the different types that exist. It will help you determine which type of RV heater would be more suitable for your situation. So, here are the three most common types and their benefits and disadvantages.

Propane RV Heaters

The first most common type of RV heaters is a propane powered unit. They operate by using combustion to provide heat. When you ignite it using either a pilot light or an electric sparker, it fires up the burners located in the combustion chamber. The produced heat then flows into the next chamber, which is called the heat exchange chamber. The temperature here rises and then with the help of a vent it blows out into the room through the vent, warming your recreational vehicle.

The main benefit of a propane RV heater is that it doesn’t require any electricity for operation. So, if you’re boondocking and away from any source of electricity, you won’t have to worry about getting cold. And you also won’t have to worry about the heater draining your RV battery. On top of that, propane heaters also offer benefits such as energy efficiency, low cost, and low pollution.

However, there are also downsides to propane RV heaters. First of all, they require constant refilling and hauling of the fuel canisters. Secondly, they can be dangerous if the gas tank or tube start leaking, letting the gas escape. The dangerous gas can also escape if the heater malfunctions or if it’s used incorrectly. Since propane is highly flammable and dangerous for your health, this can be a real hazard. And if you’re using propane, it’s important to have a propane regulator.

Moreover, not all propane heaters are safe for use indoors due to the risk of carbon monoxide poisoning. And if a propane heater is designed for use indoors, you still have to take certain precautions. You should make sure that the area the heater is placed in is well ventilated. And you should never leave the heater unattended, especially when you’re sleeping.

Electric RV Heaters

Another popular type of RV heaters is an electric space heater. These units operate by passing an electric current through a resistor, which then converts it to heat.

One of the main advantages of electric heaters is that they don’t produce any by-products. This means that you don’t need any ducts or vents for their safe operation. Moreover, you don’t need to constantly haul fuel canisters and they take up less space since they don’t require extra space for the fuel canister storage.

As for the downsides, electric RV heaters can use a lot of energy, which can be draining for your RV battery. And they’re also unreliable when operating at elevations above 7,000 feet above sea level.

If you do choose an electric RV heater, opt for a model that is energy efficient and which offers the most essential safety features, which should include tip over and overheat protection.

There are also different subtypes of electric heaters. They can be radiant or fan-forced heaters.

  1. Radiant heaters use powerful infrared rays that are focused on heating nearby objects, such as the walls, floor, people, etc. The objects absorb this heat and then emit it into the air. Radiant heating has a number of advantages. It’s usually more efficient than fan-forced or convection heating. They are also great for allergy sufferers since they don’t spread the allergens as the fan-forced heaters do. Moreover, they are also effective at keeping the warmth longer since the objects retain the heat for a longer period of time. However, the downside is that it takes longer for them to warm a room to a certain temperature.
  2. Fan-forced heaters push the air through a heated electric element (usually a ceramic element) and then force it through a fan into the air. This provides better circulation of hot air in the room and even distribution of it into all the corners of the RV’s space. This also translates to faster heating of the overall room temperature. On the flip side, however, these units are less energy efficient and the fan operation makes them significantly louder.

Oil Heaters

Another option for an RV heater is an oil filled type of heater. These units work by burning oil in a sealed compartment. It increases the temperature level in the plenum chamber and then releases into the air through vents.

Oil filled heaters provide fast warming of the air and are safe to use since they don’t produce any carbon monoxide. There’s also no combustible gas, so you don’t need to worry about a fire hazard. And they require minimal maintenance since the oil is sealed and doesn’t need any refilling.

Another advantage of oil filled heaters is that they emit warmth for a longer period of time. After you’ve turned off the heater, the heated oil inside will continue to emit warmth for some time until it cools off. This means more energy efficient heating.

2. Size

Another important factor to consider when choosing a new heater is the size of your RV or the space you’ll be heating. The larger your RV, the more powerful the heater you’ll need. And the smaller your RV, the less output you’ll need.

It’s important to choose the right size since if a heater is too small, you won’t be able to get enough warmth and if it’s too big, you’ll have an unnecessarily large unit that will be using too much energy.

In the specs of most products, you can find the recommended maximum space that a heater is capable of heating. So, just find a heater with the maximum heating capacity that would match the size of your RV.

3. Temperature Control

All heaters have different temperature controls, allowing you to choose how high you want the temperature to be. Most units have a dial control that allows you to adjust the temperature to your desired level.

It’s best to find a unit that would give you better control of the range of heat. Some heaters only offer pre-set modes with high, medium, and low levels of heat. Others also feature an adjustable thermostat, which gives even more control of creating personalized warmth comfort. Having such options will provide more versatility.

The advantage of a thermostat is also that it will provide more energy efficient operation of the heater. Instead of producing warmth at a consistent output, the heater will cycle on and off in order to keep the room temperature at the level you’ve chosen. This means that the unit will produce only the necessary amount of heat and will not waste energy on producing excessive heat.

4. Efficiency

Of course, you also want to find the most efficient RV heater since it will help you save money and will also benefit the environment. If it’s a gas heater, consider how much fuel it burns. Or if it’s an electric unit, check how much electricity it uses.

Also, depending on the type of heater, consider how fast it can heat up your space. And how long can it maintain the warmth after its operation has been shut off. However, keep in mind that some units (fan-forced heaters) warm up the air faster but don’t retain the heat for that long after, while others (radiant and oil-filled heaters) offer the opposite. So, consider what would be more important for you.

When choosing the most efficient RV heater, also make sure that you choose a unit whose heating output would match the size of your RV. If the heater is not powerful or too powerful for the space you need to heat, it will operate inefficiently, wasting too much energy.

5. Safety

You also want to find the safest RV space heater. For that, it should come with certain features built into the system.

For one, make sure that the heater has tip over protection. If it doesn’t and the heater gets knocked over, it can become a dangerous fire hazard. It’s especially important if you have kids or pets in your RV, which could increase the risk of the heater getting dipped over.

Another important safety feature that a heater should have is overheating protection. This feature will ensure that even if you leave the heater on for a long time, it will not overheat and will not cause a fire. Overheat protection provides automatic shut off in case the temperature of the internal components reaching a dangerous level.

One more feature that a good electric heater should have is housing that stays cool to the touch. It will ensure greater safety and will protect your RV companions from potential burns.

6. Noise Output

One more thing to consider when buying an RV heater is its noise output since some units operate more quietly than others. It’s best if you can find a heater that would produce minimal noise, so it wouldn’t be disturbing or uncomfortable operating in your RV.

When considering the noise aspect, it’s important to point out that certain types of heaters are noisier than others. In particular, fan-forced heaters are usually the noisiest. While they are effective at heating larger spaces, they can also be distractingly noisy.

Radiant heaters, on the other hand, are the quietest ones. They are basically completely silent since they don’t have any fan operation and they emit heat in the form of electromagnetic waves.

7. Durability

Since you don’t want your money to be wasted, look for a heater that offers great durability. It should have a sturdy design with no flimsy parts that could potentially break. It’s important that the device lasts through years of use providing consistent warmth and comfort.

8. Portability

If you’re choosing an RV space heater, consider also the portability of the unit. Look for a heater that is relatively lightweight and compact. It’s also a benefit if it comes with a built-in carrying handle, so you could easily pick the unit up and move it around.

The portability of your space heater will give you more control of where to have the warmth. You could move it between rooms or place it closer to you. Due to this, you’ll be able to stay warm no matter where you are in the RV.

9. Maintenance

Consider also how easy or hard it is to maintain the space heater. For example, if it’s a propane heater, it will require more maintenance since you’ll need to regularly refill the gas canisters. With electric heaters, on the other hand, there’s less maintenance.

10. Cost

The price of the heater should also play a determining role in your buying decision. It shouldn’t be the only determining factor but it should definitely play into your decision. We recommend setting a budget and looking for a heater model that would fit into this budget. This would ensure that you don’t overspend and it will help to narrow down your options to a more manageable amount, which would make choosing the perfect heater a lot easier.

Safety Guidelines For Using a Space Heater in an RV

  5. Read the manufacturer’s instructions and always follow them for proper heater usage and maintenance.
  6. If you have children or pets, supervise them when they are in the room with the heater.
  7. Regularly check detectors for smoke and carbon monoxide.
