When you are full-time, you will hit winter sooner or later. My friends and I usually spend our winter in AZ, NV, or CA for warmer climates. Even though I sleep with multiple blankets and don’t usually need a heater for the night, I still need something to keep me warm during the evenings. I sometimes have electric hook-up, so instead of running my propane furnace, I use small ceramic heaters. Other times, I just now use my Wave propane radiant heater. I personally love it.

This expensive heater is the best small RV space heater and is worth every penny. It’s way more efficient than other types of propane heaters. The RV furnace is the worst! I have a small 1-gallon propane tank I connect it with and use it to heat my rig during the evenings, I just have to make sure I have enough ventilation. While you don’t have to get yourself the same heater as I use. At the end of the day, it all boils down to personal preferences, space availability, and budget.

All you have to do is get yourself an RV heater that suits you. RV heaters are very convenient since they are very good in energy efficiency. You can just plug them into your electric hook-up and be set. Durability is also another advantage that RV heaters have. RV heaters are also very cost-efficient. They’re energy-efficient and affordable, making them very ideal for people who live or stay in RV parks. There are a lot of options to choose from, and there’s bound to be one that suits your needs.

Given that you know how to take care of it, your space heater should last you a very long time.

Here are some things that you can do to prolong the life of your RV heater:

If you use an electric heater, unplug the electric cord when it’s not in use. This way, you save power and prevent overheating which could cause damage to your heater if left plugged in for too long. You can use most heaters overnight, but if it’s not freezing cold, consider using more blankets rather than having your heater on. It might seem logical to just leave it running overnight, but even an ordinary space heater could be a fire hazard if left plugged in while you sleep. Make sure you have a fire alarm.

Clean with a damp cloth. When you clean your electric RV heater, unplug the cord and remove any dirt or dust with a damp cloth. DO NOT use water to rinse it down because that could damage the heater’s heating element. If there is stubborn dirt or dust on your electric space heater, just use a vacuum cleaner with soft bristles to brush them off.

Buy a cover for it. Most RV heaters come with a cover, but if yours doesn’t and you feel like getting one is necessary, then go ahead and buy another cover. A cover can prevent dust from accumulating inside your heater and might even keep small animals out of it too.

Space Consideration When Buying RV Heaters

There are some factors that you must consider before purchasing an RV heater. Since space can be quite limited inside RVs, you need to consider how much room your heater will take up. Make sure that the one you’re buying is able to fit in the spot where you want it to be. If there’s not enough clearance under or behind your bed to place your heater, then don’t get that particular model.

The wrong size may also result in overheating, which would damage your heater. This poses a fire hazard, not to mention the possibility of you getting burnt or your RV catching fire. With that in mind, buying a heater with suitable ventilation also plays a crucial role.

If you have full hook-ups and electricity, you can use a small electric heater. If you are boondocking, you will be better off with a propane heater or your furnace. Your furnace wastes so much propane, which is why you might want to think of alternatives.

When using heaters, you have to ensure that your smoke detector works. Place the smoke detector a few feet above your heater. If you’re using propane, make sure to use a small heater with high BTU output.

Bottom line: When looking for a small RV space heater, you want something that’s cost-efficient and easy to run. You also need something that can fit in tight spaces and not take up too much room. It should also be easy to move around and shouldn’t be a fire hazard.

These are the ones I found to have the best reviews.

Types of Heaters

There are two different types of RV heaters; radiant heaters and conventional heaters. Radiant heaters work by heating the objects in the room, while convectional heaters work by circulating heat in the surrounding air in the room. Convectional heaters are more common than radiant heaters.

Radiant heaters

Radiant heaters are generally safe to use around children and pets because they don’t emit any hot air. However, make sure that the area is well-ventilated to avoid overheating or fire hazards. When you buy an RV heater, make sure to get one with a tip-over switch. This way, the heater will automatically turn off if it falls over.

Convectional heaters

These are usually recommended for use in RVs because they work similarly to the furnaces found in most homes. They have a fan that blows air over a heating element. The air will be heated, become lighter, and rise up to the ceiling while some of it falls back down again. This cycle repeats until all the air in the room has been circulated.

RV Heater Safety Tips

No matter what type of heater you’re bringing into your RV, it’s important to keep safety in mind. Make sure that your electrical system can handle a load of your new heater or furnaces before plugging them in. If you’re not sure, it’s a good idea to call your electrical system manufacturer and ask.

If you will be using either of these heaters in enclosed spaces such as garages or tents, make sure there is proper ventilation; this prevents carbon monoxide build-up inside those spaces.

Be mindful of any pets or children that may go into these spaces. Both propane and kerosene heaters can put out quite a bit of carbon monoxide.

If your heater is not working properly, unplug it, let it cool down, and fill up the tank with fresh fuel. If that does not work, you should stop using it immediately.
