Safest Space Heater For RV - Buying Guide

Types of RV Space Heaters

Here are the three main types of portable heaters that you can use in an RV.

Electric Heater For RV 

Depending on your experience and comfort level, you may prefer using an electric RV heater.

It requires less upkeep and doesn’t constitute a suffocation risk as it doesn’t produce any toxic emissions which in turn keeps the air cleaner.

Electric heaters are generally easier and safer to run than gas heaters.

There are four main types of electric heaters: convection heaters, fan-forced heaters, radiant heaters and infrared heaters. The main difference being their method of producing heat.

  • Convection Heaters

Convection heaters use convection currents to maintain spaces at high temperatures. The currents circulate throughout the body of the appliance and across its heating elements.

The good thing about convection heaters is that their surfaces don’t get too hot making them a safe choice in RVs.

  • Fan-Forced Heaters

Fan-forced heaters work by using a fan to pass air over heated coils and out into the air. Fan-forced can heat your RV quicker than a heater without a fan but they are of course, noisier.

  • Radiant and Infrared Heaters

Radiant heaters transfer the heat they generate directly to people and objects nearby. They’re slower than fan-forced heaters but are really effective at keeping a space warm.

They’re an ideal choice in smaller campers where people can remain in direct line of sight of the heater.

Another benefit of this type of heater is that they don’t get as hot to the touch as other electric heaters.

All in all, electric heaters are a great option to keep your RV warm. However, since they do draw a lot of power, these are ideal if you have a powered site.

RV Gas Heaters

Something to consider before purchasing a heater for your RV is whether you will have access to electricity or not. In the event you’re not near a plug-in, a propane or diesel heater is likely the more reliable choice.

Gas heaters can heat up small spaces really quickly. They’re easy to use and can provide heat over long periods. As an example, the Mr Heater Big Buddy propane heater runs for 4 hours on high and up to 8 hours on low setting on two 1-pound propane canisters. With a 20-pound propane tank it can provide up to 100 hours of heat.

If you understand that heating an RV with a gas heater requires some ventilation and you follow the manufacturer’s safety measures, you shouldn’t encounter any issues with this type of RV heater.

How To Choose The Safest Space Heater For Your RV

Safety is always the first thing to keep in mind when choosing a portable space heater for your RV. So when considering purchasing a new space heater for your RV, there are a few factors you should take into consideration.

Of course, price is always a factor and you need to look at the options that fit your budget, but here are a few other things to consider:

Electric Versus Gas Or Diesel

Some people prefer electric over fuel, and that really boils down to personal preferences because there are plenty of options for the safest space heaters for RV’s using both of these options.

When looking at our Best pick above for the safest space heaters for your RV, the Mr. Heater Big Buddy is the most efficient choice and the safest one we’ve used with an RV propane heater.

However; if the electric is your preference – then definitely check out the Heat Storm Space Heater above for the Best Electric Heater for your RV simply because it uses 110 volts and the infrared system is incredibly energy efficient!

The Size Of Your RV Space That Needs To Be Heated

The safest space heaters for RV’s will vary in different sizes and watts. So be sure to take this into consideration when thinking about buying one.

Our premium pick above, the Webasto Diesel Heater RV is great for the larger RV’s – it can heat up your entire RV and then some, yeah, it’s that powerful! So if you like it toasty inside your RV, you’ll definitely want to check this one out!

Kid And Pet Friendly

The Heat Storm Space Heater above was our pick for the Best Electric Heater for your RV for a lot of reasons, including being kid and pet friendly! Nothing more important than keeping your loved ones safe while keeping them cozy and warm.

We want you to be warm, comfortable, and SAFE when using a space heater in your RV. So below are a few things you can do to get yourself prepared and make your experience memorable for the sights, not the problems you might encounter if you don’t follow some important guidelines.


7 Tips For Reducing Risks While Using an RV Space Heater

  • Read that instruction manual (twice if you need to) and then follow the instructions to the tee. Don’t take shortcuts, these often end up being unnecessary risks.
  • Location, Location, Location! Be sure to place or install your space heater out of the way from pets and children. It should also not be in a heavy traffic area, just look for an open space on level ground that is out of the way.
  • Now you need to make sure the one you purchase has safety measures that include automatic shut-off when being knocked over.
  • Make sure you plug your space heater directly into an outlet – do NOT use extension cords and be sure to keep any flammable items at least 3 to 5 feet away from your RV space heater.
  • It is absolutely mandatory to have adequate ventilation when using any fuel-burning space heaters and to follow the instructions of the manufacturer on how to install any additional pipes or tubes for assisting in the ventilation process.
  • Make sure your RV has proper detectors installed that can detect harmful things like carbon monoxide, smoke, and gas. These can be a lifesaver, don’t skimp on these!
  • Perform check ups before each trip to make sure that your space heater is working properly (including the CO sensors) and be sure to look at the cord and plug to make certain that they are still in perfect working condition.   

Frequently Asked Questions (FAQs)

1. Are RV Space Heaters Safe?

And with all the choices available today, the standards and regulations have made it very safe to use an RV heater.

In fact, the electric heaters are super-efficient and don’t have any odors that some of the fuel space heaters tend to give off. But there are also fuel heaters that have no smell and have been proven to be super safe as well.

However, remember that just because there isn’t a flame doesn’t automatically mean there isn’t a risk – there is always a risk when using an external heat source.

Be sure to know what amount of electrical current your RV can support if choosing to use an electric space heater.

And it’s important to know what your plug receptacles can handle – the amps can vary and you need to make sure yours will support whatever space heater you should choose to buy.

4. How To Choose The Right Size Heater For My RV?

You will need to know the approximate living space you are wanting to heat in your RV before deciding which space heater for RV’s will work best for you.

Of course, the portable modules will offer more flexibility than the mounted or fixed spaced heaters in your RV. If choosing the best electric space heater for your RV – you have a lot more options of where you want to move it and plug it in.

When choosing gas propane or diesel space heater for your RV, then you want to know the surface that needs to be heated and buy one according to your needs.

5. Can You Leave A Propane Heater On All Night?

First, it is always recommended to sleep in cooler temperatures for better sleep and improved health. But okay, some nights can be extremely cold and you might want some extra heat.

So, in this case, we suggest checking with the manufacturer’s instructions and guidelines because some propane heaters are equipped to run through the night when certain safety measures and conditions are met.

However; be mindful of how these will affect the oxygen levels in your RV and make sure the one you choose has support for allowing fresh air to come in through an attached hose or fixed pipe.   

Note: Make sure you have installed all the necessary detectors for keeping you and your loved ones safe: carbon monoxide, smoke, and fuel detectors are recommended.

6. Can You Get Carbon Monoxide Poisoning From A Propane Heater?

When using a propane space heater properly, the risk is greatly reduced. However; it’s important to know that carbon monoxide (CO) poisoning can happen within minutes and can be deadly.

It’s imperative to make sure that your RV propane heater is set up accordingly and kept in the best working condition at all times. Regular maintenance should be performed to avoid any risk of malfunctioning parts.

Be sure to always consult the manual and follow all the safety setup instructions completely to avoid any additional risks.

7. Is It Cheaper To Heat With Electricity Or Propane?

It has been proven that propane heat is more economical and much more efficient than using electricity to heat your RV. This also will depend on the National fuel prices as well, however; you will almost always find that propane is cheaper than electricity.

Now if you are staying somewhere with un-metered electricity, then by all means go for the electric heater and plug in all your extra appliances since you won’t be absorbing any of the costs.

But if you are going to wing it and stay as you go on your road trip, then perhaps an RV propane heater would be most cost-effective and the best option if looking to cut costs.

If you will be staying at an RV park most of the time, then it would be best to check with the property to see what the cost is per kilowatt of power at their establishment and then do the math to see which one would be more cost-effective for you.   

Note: Boondockers would benefit from propane for a number of reasons, but mainly because they don’t typically have the means to ‘plug up’ whenever needed.

Worth Mentioning: If you plan on buying your propane from the park or having it delivered – you will pay the highest prices and it will not be cost-effective at all!

8. Does Mr. Buddy Heater Produce Carbon Monoxide?

Mr. Buddy heaters normally come with a low oxygen sensor that will shut off automatically if it senses too little oxygen in the air, avoiding that carbon monoxide is being produced at a dangerous level. 

Nowadays, many of the other propane or gas heaters also have sensors that can be used to shut off automatically as well for the same reason.

If considering the best space heater for your RV and you are thinking of getting either a propane or diesel space heater – be sure to check with the manufacturer on how they are preventing the production of carbon monoxide.

Note: It is extremely important to make sure the sensors are kept clean and working at all times for them to work accordingly.
