Campervan LPG Ovens: Ultimate Guide

Picture this: It's a Sunday morning in the van; the timer goes and you take the freshly-baked sourdough bread out of the campervan oven. The warm, doughy bread crackles as you break a piece off. You douse it in olive oil, add a pinch of salt, a few chilli flakes, and some herbes de Provence. Your mouth waters before you've even taken a bite.


That could be you... If only you had an LPG oven.


Well! In this guide you will learn all about LPG ovens - what are the best models are and how to install one.


I'm Shane, I've been teaching people to convert campervans for many years, I'm the author of The Van Conversion Newsletter, the van conversion instructor at Udemy, and the proud owner of a beautiful self-build campervan called Beans. So let's jump in and see how to install a campervan oven and hob!

Do you need a campervan oven?

To be completely honest, LPG Ovens are more of a 'nice-to-have' rather than a necessity. However, if you live for an extended period on the road and really want to make your van feel like home, a campervan oven can be a fantastic addition! They bake bread, they make pizza, and they look great!


Once your LPG system is setup, installing the LPG oven is actually very easy! The question is not one of technicality, but moreseo one of space and money.


Campervan oven size

An LPG oven is bigger than a simple gas hob. There's no getting around that fact. You should probably only consider getting an LPG oven if they have a long-wheel base van (or bigger). Because it can take up a lot of room, I recommend noting the oven location when you are your designing your van (in software or on paper) at the outset.


To give you an idea of size, the popular (and slim) Dometic Sunlight has the following dimensions:

  • Depth: 357 mm

  • Height: 398 mm

  • Width 449 mm

Luckily for us, there are many campervan oven options (some of which are very small indeed) - we will look at our options in the next section.


LPG oven cost

Believe it or not there are some really good value LPG ovens out there (considering what you get)! For a traditional campervan oven prices range from €300-€1300. Though as we will look at in the next section, there are some super cheap alternatives that you could look at!



What is the best LPG oven?

Omnia Camp Oven

Before we get into more traditional LPG ovens, I want to give a shoutout to an excellent, cheap, and tiny alternative: The Omnia camp oven!


Also known as the 'wonder pot', this stovetop oven is perfect for campervans. The donut-shaped design gives an even heat all around the food - the top and the bottom.

Dometic-SMEV Oven and grill

The Dometic-SMEV is one of the most popular campervan oven and hobs on the market. It is cheap, small, and does the job!

Dometic Smev campervan oven

  • 12v ignition

  • 20 litre oven

  • Thermostat

  • Interior light

  • Combined oven and grill

  • 530 x 310 x 410 mm

  • Oven output: 1kW

Note: The old Dometic-SMEV oven must be ducted to a roof-mounted flue! It comes with the chimney connection for this job.


Thetford-Spinflo Duplex Oven and grill

The Thetford-Spinflo Duplex oven is another very popular LPG oven. It is bigger and more powerful than the Dometic-SMEV.

Thetford Duplex campervan oven
  • Piezo ignition

  • 36 litre oven

  • Thermostat

  • Combined oven and grill

  • 456 x 445 x 440 mm

  • Oven output: 1.5kW

An alternative to the Thetford duplex is the Thetford Triplex, which is a combined campervan oven and hob! Super handy and space efficient.


Note: You must install a drop-out vent underneath both the Duplex and Triplex ovens. Ensure you follow the specifications set out in the manual.


Voyager 4500 LPG oven and hob

The Voyager 4500 campervan oven and hob is another very popular option.

It has a dedicated oven, grill, and hob - all delivered in a very compact size.

Voyager 4500 LPG oven and hob
  • Battery ignition (no 12v required)

  • 19.8 litre oven

  • Thermostat

  • LPG grill, oven and hob

  • 530 x 485 x 410 mm

  • Oven output: 1.26kW


Road Chef 12v Oven

The Road chef is a 12v oven... how about that! No need for any LPG, just hook it up to your leisure batteries!


With one caveat... it has a draw of 8.5a, so you better have some big batteries and thick cables!

12v oven

  • Thermostat & timer

  • Oven only

  • Heats to 180C

  • 190 x 320 x 280 mm

Campervan oven and hob safety

  • Ensure your campervan is very well ventilated (ie. Install a fan!)

  • Many LPG ovens require either a dropout vent or roof exhaust flue

  • The surrounding material must be able to withstand a certain amount of heat - do not put flammable material right beside the oven and check the manufacturer's guidelines to find out what heat is output

  • Get the gas installation done by a professional

  • Keep a fire extinguisher in your van

  • Install a carbon monoxide detector and smoke alarm

  • Install a gas leak detector (mount near the floor - gas is heavier than air)


LPG oven installation guide

The specific installation steps for an LPG oven differs from model to model. For example, if you have a Dometic-SMEV, you will need a chimney flue, whereas if you have a Thetford, you need a drop-out vent.


The installation instructions provided below are presented as a generic guide - always follow the instruction manual provided by the manufacturer.


I highly recommend you read this guide about campervan gas installations in this guide. Gas installations should be carried out by a registered gas fitter, and at the very least checked by one. Gas is very dangerous and a gas system must be fitted correctly. Campervan oven and hobs get very hot and the utmost care should be taken when installing them.


With all that being said... Let's hop in and look at how to installation and LPG oven! In particular, we will be looking at installing the Thetford Triplex, though the steps are similar for most ovens!


1. Build the wooden support frame for the campervan oven

Your campervan oven will likely go in the kitchen unit of your van - ensure you have left enough room there for the installation!


When building the support frame, follow the exact specifications laid out in the instruction manual for the oven. For example, these are the measurements for the Thetford Triplex:

LPG oven and hob dimensions

To do this carpentry you just need a jigsaw and some plywood.


You must install a drop-out vent underneath the oven - though not somewhere that will cause a draught to come in (which could potentially disrupt combustion). The drop out vent is in the cavity under the oven. You can cut the drop-out vent using a holesaw.


The oven must be 10mm away from the wood on the left and right sides. There must be a gap of 80mm at the back of the oven.

LPG oven cabinet

The surrounding material must be able to withstand temperatures of 65C above ambient temperature. For this reason, if you live somewhere very warm, you should install cement (hardie) board all around the campervan oven. Cement board can withstand much higher temperatures than plywood.

Cement board heat resistant lpg oven

There was an excellent guide written by Wanderwoods about how to install an outdoor oven inside - which requires the use of cement board + reflectix due to it's high temperature. The photo above is taken from their build.


When you are sure you have followed the instructions specifications to a tee, you can push the LPG oven into the space.

Installing an LPG oven

2. Connect the gas

Attach the gas pipe (rigid pipe required by BS EN 1949:2021 standards) to the campervan oven inlet using an 8mm brass compression fitting


Ensure you put jointing compound/pipe dope on the oive/ferrule in the fitting. Tighten the fitting hand tight and then tighten it another 1.5-2 times with a wrench.

Gas connection to LPG oven and hob

You can learn all about campervan gas installations in this guide.


But again: Gas installations should be carried out by a registered gas fitter! And at the very least checked by one. Gas is very dangerous and a gas system must be fitted correctly.


3. Hook up the electrics

The last thing to do is hook up the electrics! The power is simply for the 12v ignition (assuming you don't have a piezo ignition). So go ahead and wire the oven up to your leisure batteries. Don't forget to fuse it (usually 3a fuse)!


4. Enjoy!
