What You Should Know Before Buying Propane Heaters For Rv

Safety Features

Every RV has a different heating system, but all of them have common safety features. For example, many older RV heaters came with an open flame that was designed to be lit by the user on demand. However, this type of heater also included several warnings about having adequate ventilation when it was in use. Today’s models rarely include flame-based lamps and instead promote electric elements (such as ceramic plates) or propane burners that are often equipped with oxygen sensors and automatic shutoff switches for added safety.

Many modern RV heaters also come with thermostats to automatically adjust heat levels based on the external temperature inside your home away from home. This means you don’t have to worry about leaving any children or pets inside your RV without adequate heating or cooling.

Although many RV heaters are designed with safety features that reduce the risk of accidental fires, accidents still happen. That’s why it’s also important for you to take steps toward being prepared in case something does go wrong while you’re enjoying your vacation away from home. For example, having an extinguisher nearby will enable you to put out any flames immediately when they ignite – but only if you know how!


Electricity is a popular source of power for RV heaters since electricity is considered a greener and more environmentally friendly source of energy as well as relatively safe and familiar. Different electric space heaters include ceramic, fan, infrared, oil-filled, and panel.

A downside of electricity is that if you do not have a supply of electricity nearby, from a campsite or a house, it is difficult if not impossible to generate enough electricity to supply high energy demands from heaters, especially over long periods.

Using gas as a fuel is often convenient in that gas is easy to store as a fuel source – such as a gas tank – and cheap to buy, meaning the running cost when compared to that of electricity is often comparable if not better. Generally, LPG (Liquefied petroleum gas) is used either in the form of propane or butane – propane most commonly although many gas heaters will accept both

Gas heaters can often be a little daunting for people who have gone their entire life using only electricity to perform heating. On top of this gas is often dangerous to store and use because of how combustible it is when released and converted from the liquid state is stored into its gas form.

Another fuel source is diesel. If your vehicle runs on diesel using diesel for your heating may be very convenient as you may be storing spare diesel anyway and drawing fuel from your main diesel tank will not ruin any component of your car such as a battery.

Drawing from your main diesel tank might be a disadvantage if poor planning or unexpected circumstances forces you to choose between heating and running your vehicle or more likely not running heating lest you diminish your fuel supply. Diesel heaters are also not as quiet as electric heaters.

Wood Burning heaters are an affordable and nostalgic way to warm up when you’re far from home. Foraging for wood, depending on climate conditions can often be easy but very time-consuming. If the compartment which the wood is burning is small you will need to replace the wood at regular time intervals which can get quite tedious.

Wood burning uses large volumes of fuel which means keeping stocked up with large piles of wood. Such a thing may not be doable with limited space in your RV meaning you have to rely on the fact that you will meet a wood source regularly. Having an open flame exposure is dangerous as you risk things within your RV catching fire. Carbon monoxide poisoning could ensue as well- especially using a wood burner indoors without proper ventilation (you should also enforce height restrictions).

Disadvantages Of Propane Heaters

Disadvantages of propane heaters

• Carbon monoxide poisoning. Propane heaters – especially those intended for outdoor use – need good ventilation or you could get carbon monoxide poisoning. Good ventilation also means that the hot air is escaping, and cold air is coming in. This means that when your propane runs out or your heater is turned off, your RV can become cold very quickly because of the increased supply of cold air.

• Carbon Monoxide is tasteless and odourless gas which is the product of incomplete combustion. If your propane heater is functioning properly, you shouldn’t be in danger of Carbon Monoxide poisoning. Indoor propane heaters sometimes come with detectors that monitor the amount of oxygen in the air, detect the presence of Carbon Monoxide, and detect the presence of Liquid Propane (LP) gas in the van. It does not hurt, however, to have your own detectors as well because if something goes wrong you could very well end up dead. Even if the combustion takes place outside you should still have these detectors to stay safe.

• Propane manufacturers deliberately give it a “rotten egg” smell to make it detectible so it may be unpleasant to burn indoors.

• Water vapor is also created through the burning of propane, this may lead to unpleasant humidity when you wake up.

• Propane tanks can sometimes leak. Propane tanks are often not designed to withstand the abuse that might come with being knocked about in a vehicle. Tanks will vent out a little bit of gas to cope with the pressure.

• Propane heaters are also dangerous to run while driving because if you got into an accident, you risk an explosion or fire with an open propane tank.

Propane Tank Size

Propane tank sizes

Heat production is measured in BTUs (British Thermal Unit). The higher the BTUs something produces the greater its heating power. A room’s BTU requirement is dependant on the cubic volume of a space. To calculate the BTUs per square foot you take the square footage and multiply it by 20 BTUs for a warm climate and 50 BTUs for a cold climate.

Class A motorhomes are the biggest and can have lengths from 21 feet to 45 feet, 33 feet on average, widths of 9.5 feet on average. This means they could be anything from 199.5 square feet to 427.5 square feet and on average 313.5 square feet. This would mean a BTU requirement of 3,990 to 8,550 (average 6, 310) BTU in a warm climate and 9,975 to 21,375 (average 15,675) BTU in a cold climate.

Class C motorhomes are between 20 – 33 feet, on average 28 feet, in length and are 9 feet in width. This means a volume of 180 to 297 (average 252) square feet. This would mean a BTU requirement of 3,600 to 5,940 (average 5, 040) BTU in a warm climate and 9,000 to 14,850 (average 12,600) BTU in a cold climate.

Liquid Propane (LP) has 91,500 BTU/h per gallon, 21,548 BTU/h per pound, 47,300 BTU/h per kg, and 24,000 BTU/h per litre.

• A 30,000 BTU heater would run for

o 30 hours at 10 gallons

o 7 hours at 10 pounds

o 15 hours at 10 kgs

o 8 hours at 10 litres.

• A 9,000 BTU heater would run for

o 101 hours at 10 gal

o 23 hours at 10 lb

o 52 hours at 10 kg

o 26 hours at 10 l.

Now that you know how many hours of heating different sizes of propane tanks will get you, you should consider other matters such as where you will store the propane tank, how you will move the tank around, how you will store extra propane tanks for the gaps between refills and how much risk you are prepared to put yourself under when storing large amounts of propane.

Questions and Answers About Propane Heaters For Rv

Is it safe to use a propane heater?

If the propane heater is working properly then it is safe to use a propane heater. You should, however, take precautions such as detectors that monitor the amount of oxygen in the air, detect the presence of Carbon Monoxide and detect the presence of Liquid Propane (LP) gas in the van.
It might also help to stow propane tanks somewhere soft and fireproof so that the tanks do not rattle when you travel and cause a build-up of pressure when traveling.
It is also essential to have good ventilation when using a propane heater.

How much ventilation is needed for a propane heater?

The amount of ventilation a propane heater needs is dependent on the heat output of the propane heater within a given amount of space. The more propane is burnt within a given amount of space the more ventilation is required within that space. There is no exact science as to how much ventilation you will need because the air will escape at higher/lower rates depending on how high the vent is within the RV and how obstructed it is. Air may also escape at different rates depending on how well insulated your RV is.
Overdoing the ventilation may make you susceptible to leaks, cold air, and moisture, effectively nullifying all the work your propane heater has done.
All in all, it is most important to have multiple sensors which detect the amount of oxygen in the air, the presence of Carbon Monoxide, and the presence of Liquid Propane (LP) gas in the van. In this way, you can increase your ventilation if you are detecting the presence of dangerous gases.

Do propane heaters use a lot of propane?

The amount of propane a propane heater uses is dependent on many factors on factors which affect the heat output requirement such as the climate and size of space. A cold climate will require more heat output than a warm climate. A large space will require more heat output than a large space.
A 9,000 BTU heater would run for around 23 hours with 10 lb of propane. A 30,000 BTU heater would run for just 7 hours at 10b of propane.

Can you run propane heater in RV while driving?

You can run a propane heater in an RV while driving but doing such a thing would be inadvisable because of how dangerous it is. When the vehicle is in motion is could mean that the things within your RV will be knocked about if not stowed away properly or at least vibrate. Being knocked about in your RV could cause the pressure within the gas tank to build up, meaning that the tank will release a small amount of gas to cope with the pressure so that the tank does not explode. This could mean small amounts of flammable, ignitable gas floating around your RV as you drive.
Getting into a crash might be made markedly more dangerous by using a propane heater as you could risk an explosion or fire with an open propane tank.
