A Heated Debate: What's the Best Caravan Heater?

Travelling in colder climates? You don't want to set off only to find that your caravan heater doesn't keep you warm when the temperature drops.

That's why you need to make sure you buy the best caravan heater on the market.

The good news is there are lots of great models to choose from, with lots of innovations to make your trip more comfortable. The bad news is you still have to narrow down the choices to decide which one is right for you.

In this article, we compare the top caravan heaters and the brands you should consider.


Gas vs Diesel Caravan Heater:

Depending on the type of fuel, you have a few different caravan heaters to choose from.

The main types of caravan heaters are Gas Caravan Heaters and Diesel Caravan Heaters.

Take a look at how they compare:


Gas Caravan Heaters:

Gas heaters connect straight to your gas bottle, which has the advantage of running independently from the engine and providing an economical heat source. Granted, old gas caravan heaters have a bad reputation for guzzling gas and being expensive to run. But technology has come a long way and the modern units offer a higher level of efficiency and low power consumption.

How efficient are we talking? Gas caravan heaters can generally heat an average caravan in just 30 minutes.

You can also look for models with lower exhaust emissions, if you're worried about your carbon footprint. This makes them kinder for the environment and quieter too - a big bonus for travellers.

Whichever model you buy, ventilation is critical. Ensure your unit is installed and certified by a qualified, licensed gas fitter.


Pros Of Gas Caravan Heaters:

  • Gas setup is ready. If you have a gas cooker, water heater and even a three-way fridge, the gas is already installed and ready for the heater.

  • Runs independently from the engine. A gas heater runs off a gas bottle directly.

  • Super quiet. The only part that makes a noise is the fan. Some heaters, like the Truma Vario Eco Gas Heater, offer near silent operation so you can run it through the night without disturbing your sleep.

  • Cheaper than diesel. They are cheaper upfront.


Cons Of Gas Caravan Heaters:

  • Regulations. Gas heaters must be installed by a licensed gas fitter in accordance to gas regulations - this is a big downside and may rule out a gas heater for your van. A gas heater flue cannot be installed too close to a door, window, another gas appliance inlet or outlet, and so on. However, if space is an issue, Truma offers compact gas heaters that can be installed almost anywhere.

  • Higher demand on gas supply. Putting more demand on your gas supply could be an issue if you're in the bush with limited gas refill options.


Diesel Caravan Heaters:

Diesel caravan heaters are designed in two parts - the fuel tank, exhaust and air intake are mounted externally, then, you can have one, two or three air outlets inside the caravan for heating.

Alternatively, you can choose to tap into the fuel line of your diesel-powered motorhome for the heater.

The downside of this is that it can be costly upfront. But in the long term, it could be the economical option for your caravan, especially if it's on the larger side and you plan on spending lots of time in cooler climates.

Pro tip: if you are looking for a budget diesel heater, we recommend these units:


Pros Of Diesel Caravan Heaters:

  • Readily available fuel source, if you already have a diesel vehicle. The heater can access fuel directly from the vehicle's tank.

  • Extremely efficient. Caravan diesel heaters are a highly efficient form of heating with low fuel consumption.

  • Installation is flexible. Diesel units have an exhaust that goes through the floor of the vehicle, rather than a flue that goes through the wall like gas units. This means installation can be more flexible and there's no need for a qualified tradie.

  • Pre-warm the van. You can use a diesel heater while you're driving to pre-warm the caravan interior ready for arrival.

  • Clean dry heat. No need to worry about the humidity and condensation that you can get from gas caravan heaters.


Cons Of Diesel Heaters:

  • Requires a diesel fuel tank. If you don't have a diesel fuel tank, it can be an expensive option.

  • More expensive than LG gas heaters. The cost of a diesel heater can be a barrier for some, but their value is in the long-term efficiency which means they can be more economical for larger vans.

  • Louder than gas heaters. Reduce noise issues by choosing a quality unit and ensuring it is properly installed.


Electric Caravan Heaters:

Electric caravan heaters offer a good alternative to gas and diesel models. You can buy an e-kit for the Truma VarioHeat so that it can run off electricity when you want to save your gas, or gas AND electric for turbo-charged heating.


The E-Kit comes with two individual heating coils that can be used independently for 900W of additional heating, or together for a full 1800W of extra heating power.

Now you've decided on the type of caravan heater, take a look at the top brands:
