10 Best Electric Heater for RV 2019 – Ultimate Guide

Traveling in an RV is a fun experience, but it can become uncomfortable really fast if you do not have a good electric heater installed in it. RVs generally suffer from lack of proper insulation and also allow the cold air from outside to leak in which can make it quite chilly inside without a heater.

If you are thinking of taking a trip in your RV during the winters or are planning to camp in open and windy areas, an electric heater will be indispensable for you to have a warm night’s sleep in your RV.

Safety Precautions – Ensure That You’re Safe Throughout

Heaters are really useful devices which can provide you a lot of comfort on a cold evening. But they are also potentially dangerous devices which can prove to be a safety hazard if proper precautions are not taken. Make sure that you keep the following safety precautions in mind while using electric heaters in your RV:

  • Never leave a heater unattended or leave it running when going to sleep. Make sure to turn off the heater if you are exiting the room or preparing to settle in for the night.
  • Heaters are only meant for heating the room and should not be used for cooking, heating the bedding, drying clothes or thawing.
  • They should be ideally placed where there is a minimum chance of people knocking into them. Highly flammable items like papers, clothes, rugs and the likes should not be kept near the heater.
  • The heaters should generally not be plugged into extension cords but rather directly in the wall plug itself.
  • The heater should be from a good company and should have been tested for safety at a laboratory.
  • Heaters which have frayed wires or any kind of broken parts should never be used unless repaired properly.
  • They should be placed directly on the floor and not on carpet or another piece of furniture.
  • If you regularly use heaters in your RV, you should also have a smoke alarm installed just in case of emergency.

What is BTU?

In terms of electrical heaters, BTU is used to help the user understand how much heat can be produced by that electrical heater. For example, a heater with a higher BTU will obviously produce more heat while that with a lower BTU will be a low-powered one.

The BTU level of an electric heater is an important feature to consider as it will help you pick the right size of the heater which is required for your RV. By knowing the BTU, you can easily know the heat output of the heater that you are considering. You can then find out the square footage of the room that you want to use the heater so that you can calculate whether the BTU level of the heater is sufficient for heating up that room quickly and efficiently.

Types of Electric Heaters for RV

When you browse for electric heaters in the market, you will generally come across three common types of electric heaters which you can choose from.

Electric HeatersOil HeatersPropane heaters

These are the most common type of heaters in the market which run on electricity and can be found in two variants – radiation type and blower-fan type. The radiation heaters simply work on the rod heating system and just like their name suggests, they radiate heat which heats up the air around them.

On the other hand, blower-fan heaters are those which have an inbuilt fan which throws out warm air. Both the heaters are excellent choices for RVs. If you prefer a more consistent temperature for a longer period of time, you would like to go for a radiation heater. However, if you want the RV to be heated up as quickly as possible after switching on the heater, you should go for the blower type heaters.

An oil-filled electric heater is also a great choice for RVs as it works on its own fuel supply and does not need batteries that can die out in the middle of the trip. Oil heaters are less in demand as compared to the typical radiation electric heaters since they are less energy-efficient and are also not very eco-friendly.

However, if you are planning to travel to extremely high altitudes in your RV or to very cold states, then you can consider buying an oil heater as they definitely produce a lot of heat and can keep the RV warm and snug for long periods of time.

Most of the portable heaters work on propane gas and are preferred by those who need heaters for the RV as well as for heating up their rooms when they are not traveling or for heating up their tent while camping.

Propane heaters are a good choice if you are going to be on the road for a long period of time since you can just carry an extra cylinder of gas to refuel the heater instead of being dependent on electricity connection.

Buyers Guide  – Choosing the Best Electric Heater for RV

Getting an electric heater for your RV is a great idea. However, there are so many choices in the market that it can get difficult for a first-time buyer to get the perfect heater for their RV. To make it easier for you, here is our buyer’s guide on what to look for in an electric heater before choosing the one that you want to buy:

  • Safety & Fire Hazards
    Best Generator for RV - Fire Hazard

When choosing a heater, you must make sure that it is tested for safety by the company with a proper certificate for standard safety checks. It should also have at least the basic safety features such as automatic shutdown on overheating or knocking over. If the heater has additional safety features such as a safety grill, cool to touch surface or CO2 sensors, it would be even better.

  • The efficiency of an electric heater

The efficiency of an electric heater largely depends on whether you have chosen the right sized heater for your RV. In order to ensure that your electric heater heats up the RV efficiently with low power consumption, you should choose a heater after considering its BTU as well as the size of the room that you want to heat.

For example, if you want to heat a 300 sq. ft. room, you should go for a heater which has a BTU of up to 7,000 per hour. The efficiency of a heater is also highly dependent on how much insulation the RV has.

  • Portability

Best Electric Heater - Olympian Catalytic Heater

Having a portable heater is always a good idea as it can then be used to heat up your room when you are not traveling in your RV. Generally, all the propane fuelled heaters are portable but you can even get the standard electric or oil heaters in portable versions.

Moreover, portability also comes in use when you just want to position the heater in different positions so as to bring it closer to where you are sitting or if you want to change the direction of the air of the blower. You can even consider using a portable heater to heat up your tent while camping. On the other hand, a fixed or wall-mounted heater does not provide all these advantages.

  • Maintenance and Durability

If you are a first-time buyer and do not have much idea about the functioning of a heater, you should probably go for the most low maintenance option among heaters which is the portable propane heater.

When it comes to durability, you should always check for the manufacturer’s warranty and go for a product which gives at least two years of warranty. This way you can be sure that the product has been designed to be quite durable and will not break down in the middle of a trip in your RV.

  • Cost


The cost of the heater is largely dependent on its size, the number of features as well as the brand that it is coming from. However, you can expect to buy a medium sized heater with standard features for an average of about $100. If you go for heaters which have more features such as more safety options, thermostat regulator etc., you can expect the price to be a bit steeper. On the other hand, if you want a centralized heater, you can expect to shell out as much as $500 for the same.

Wrapping up – Best Electric Heater for RV

There are a number of really good electric heaters that you can get for your RV. The trick in choosing the right heater for your RV is to correctly estimate the size of the heater by considering its BTU as well as the square footage of the RV’s interiors where the heater will be placed.

If you are still confused about which heater to buy, our top recommendation would be the Mr. Heater MH18B portable propane heater which has an adjustable BTU of 4000 to 8,000 making it an ideal heater for all kinds of RV sizes.
