A short buying guide


If you want to know how to compare the various alternatives available and choose the best RV heater for sale, you need to have a few basic rule to guide yourself after. Luckily for you, we’ve put together this buying guide to have a look at the features you’re next heater should have in order to be worthy of your attention.

Power source


To know whether an RV heater can be used both indoors and outdoors and if it can heat up larger spaces or if it’s only useful for a small room or a motorhome, you need to check and see how it can be powered.

There are generally two types of heaters, those that run on electricity and thus that can be connected to a propane tank. It’ s easy to guess which one is more suitable for which environment.

The products that run on electricity can only be used outside if you have a source nearby, while the ones the run on gas will not be of much help if you plan to use them at very high altitudes. In the end, it all comes down to your original purpose.


Temperature control


If you want to be able to properly control the output of your heating device, you need to make sure that it is equipped with easy-to-use and visible adjustment knobs.

Many designs place the adjustment knobs right on top of the heater, also painting them in bright colors to make them visible. While this is a nice feature, what really matters is the options you have to choose from.

It’s hard to incorporate everything on just one scale, so we recommend you to buy an item that features more than one knob, if possible. This way, you will be able to determine not only the temperature but also the power at which your heater operates.




We feel that there’s a need to bring up this subject considering the fact that many heating devices available for sale are only compatible with other accessories produced by the same brand.

If you feel like this is a problem, do not hesitate to look for an alternative that can be paired with any type of additional accessory.


Our top picks


In order to find a good RV heater, besides following a few tips to be able to compare between the many options offered to you, you need to know your priorities and act accordingly. We’ve taken it upon ourselves to review a few of our favorite products below to give you a starting point.



Mr. Heater F274830 Big Buddy


This model from Mr. Heater must be connected to a propane tank in order to function, and it can heat up a room of up to 300 square feet.

The heating power can vary between 4000 and 18000 BTU, and as a result, this design is 100% efficient. However, if you intend to use it at altitudes slightly above 7000 feet, the heater will shut off due to lack of oxygen.

As a matter of fact, Big Buddy’s auto shut-off function can also be activated if the pilot light goes out, not only if it detects low oxygen levels.

In order to allow you to control the temperature, this model features an adjustment knob on the top, with three slots for low, medium and high heat.

Although this is one of the best options for heating enclosed spaces like holiday cabins and so on, we must warn you not to use any unauthorized accessories if you intend to buy this product because it may cause damage.

Mr. Heater F232000 Buddy


This model is a slightly cheaper alternative also offered by Mr. Heater that is suitable for smaller spaces, up to 225 square feet, and only gives off between 4000 and 9000 BTU.

Much like the other product from this brand that we’ve also showcased in our selection, this version is approved for both indoor and outdoor use and burn clean, without producing polluting gases.

This item’s auto shutoff is triggered if the pilot light goes out or if it detects low oxygen levels, which means it may not be a good idea to use it at altitudes over 7000 feet.

In order to be easier to handle, the design includes a fold-down handle. Also, to be able to adjust the heat given off by this device you need to change the temperature using the swivel-out regulator placed on the top.

Although this product is protected by warranty, it becomes unavailable if you pair it with unauthorized accessories.

Caframo Limited 9206CABBX True North


This rather affordable model from Caframo Limited is protected by a 5-year warranty and provides reasonable quality for its price.

Featuring a low-profile design, as opposed to the other products we’ve included in our selection, this product is very easy to use since it features two adjustment knobs on the front and a variety of options to choose from.

One of the knobs is designed to adjust the power of the device while the other features a temperature scale so that you can more accurately choose the way you want to heat the space.

It also contains an anti-freezing setting, so it’s perfectly equipped to function even in extreme circumstances. The outer layer is coated with a durable finish, guaranteeing the longevity of this design.

It can be plugged in using a standard two-prong polarized plug, and it runs at 120V, meaning that it can be used in almost any indoor space, but it’s not fit for outdoor use unless you have an electricity source nearby, which makes this a good heater for a motorhome.
