Living in a caravan long term makes you think of always being in paradise. What can be better than following the sun from destination to destination? But that is not possible all the time.
If you live year round in your caravan, then you’re bound to come across cold times. By adding a diesel heater to your rig, it lets you go anywhere you want. Rather than where is the warmest at the time – and enjoy the location, rather than only the climate.
If you want to keep warm in your caravan year round, let’s look at everything you need to know about diesel heaters.
Types of Caravan Heaters
If you plan on adding a heater to your caravan, there are three different types available. LPG Gas, 240V Electricity or Diesel.
What is the difference between them?
Do you plan to stay in caravan parks which provides a 240V power supply for most of your travels? Then the best solution may be to install a reverse-cycle air-conditioning unit.
A downside is that the cost of buying the heater, as well as installation, is rather expensive. If you already have a cooling only air-conditioner, then costs can add up fast to have it switched over.
If you don’t want to spend so much on a reverse-cycle air-conditioner, then a cheaper alternative is to bring along a portable heater. The downside is 240v heaters can take up valuable space, and also become a hazard that you may bump into or trip over.
Do you want a 240V Electricity heater, and plan to travel off the beaten path away from campsites with mains electricity supply? Then the only option you have would be to bring a generator. As this type of heater uses significant power, you will need to have a large generator.
The following generators all can run on a reverse cycle:
Most caravans generally use gas for cooking. But it can also be used to heat water as well as run absorption-style fridges which has a burner attached.
As most caravans will already have a fuel supply in place, it makes adding a ducted heating solution using LPG Gas easy. The fuel is also clean-burning, and the units are not quite as noisy as the diesel heaters. quiet.
It also has some disadvantages. A certified gas installer must install the unit. There are regulations which control where they can be located in your caravan. You will also need to have enough 12V capacity to be able to run the LPG Gas heater.
As this will quickly use up your LPG gas supply, it can be difficult when you are travelling through remote parts of the country to be able to find LPG to top-up.
Many long-term travellers are choosing to make diesel their preferred choice for a heating solution. Diesel fuel is readily available throughout Australia, even in remote locations. The heating won’t also drain precious LPG supplies. But Diesel heating does need a 12V capacity for it to be able to run.
The popularity of Diesel Heating continues to increase. So, suppliers have started manufacturing installation kits for anyone with competent DIY skills. By installing the kit yourself, it can save you a significant amount of money.

Why Choose A Diesel Heater?
Diesel offers many benefits over a regular heater, for a caravan. Let’s look at the reasons why.
Safety & Regulations
Diesel heaters are widely used and considered to be very safe. They include an auto-shutdown if the system temperature exceeds a safe operating level, the same as LPG heaters.
Where diesel heaters provide extra safety is in regards to combustion and inhalation. If there is a leaking LPG fuel line, not only can it cause an explosion. It can also cause permanent nervous system and respiratory damage. Or in the most extreme case, death.
A diesel heater does not have these hazards. It is difficult to ignite, and you can also use it while you are driving. Which makes it perfect for letting you heat your caravan, even while you are still on the road to your destination.
Greater Temperature Control
LPG heaters only have a single speed fan. This is turned on and off as needed by the thermostat. Due to this, it’s difficult for LPG heaters to maintain constant room temperature. But, diesel heaters have advanced microprocessors, which allows them to control airflow and combustion. Which provides a variable fan speed and lets them keep a constant and comfortable temperature.
- A diesel heater is also cheaper than a Gas heater to run
- It is also easier to install DIY
How Diesel Heaters For Caravans Work
A diesel heater directs the cold air of the caravan by using an intake duct. It then passes over a cylindrical metal surface which is hot. This heats any air which passes through it.
The ducting then directs fan-assisted air straight to an outlet. Warm air is pushed out of the duct and enters into the caravan.
The process is repeated over and over again, which leads to heated air right through the interior of the caravan.

- Do you have enough of a payload allowance for the extra weight of the diesel heater, as well as a full tank of diesel fuel?

Diesel Heating Myths
Diesel heaters have become an affordable and popular option in recent years. But, there is still some misconceptions and doubts people have.
Let’s take a look at each one.
Are Diesel Heaters loud and noisy?
There are some diesel heaters which may make a ticking noise, Or in extreme situations sound like jet engines at takeoff. But, this is usually only common with low-end kits and poor installation.
The fuel pump must be installed using rubber mounts. This will provide insulation and prevent drumming through the chassis reel.
Kits from reputable manufacturers all include intake silencers for the fresh air intake. The way these are positioned will drastically reduce the amount of noise.
If I install the heater DIY and it is incorrectly done, can the unit catch fire?
A diesel heater can be fitted by someone who is competent at DIY projects and has a sound understanding of electronics and electrics. Make sure that you follow the instructions for installation. Also, pay close attention to both the muffler and the exhaust pipe.
Be sure not to place the muffler outlet close to any open windows. Also, ensure that the exhaust pipe is secured away from any plastics or appliances like the hot water service.
Does Diesel Heating Have a Smell?
There should not be a smell inside your caravan. But, if you have left your window open and there are strong winds, it may come inside.
Although, as diesel is a combustible fuel, upon start-up there can be a strong smell outside, which then reduces after the heater has been running. This works similarly to a generator.
