Are you tired of freezing your butt off when camping in your van? Then consider getting yourself one of the 5 diesel heaters we've covered below.

A heat-less camper van in the winter is rarely a good time. You’ve packed the family up, planned everything ahead, and are ready to embark on an adventure into the wilderness – only to spend the nights freezing your butts off.

Nothing can put a damper on your camper trip (pardon the rhyme) quite like poor air conditioning in your camper.

Luckily, you’ve got some options. There are a ton of excellent diesel heaters out there designed to efficiently heat camper vans in colder climates or seasons.

1. Eberspächer Airtronic S2-D2L

💰 Price: $1.225

Consumption: 0.28 liters/h

Eberspächer is a well-known and beloved brand that manufactures some of the best diesel heaters for camper vans that you’ll find on the market.

The Airtronic S2-D2L is one of the best of their offerings. It offers everything from automatic altitude adjustment to a silent fuel pump to dependable real-time temperature management.

You can also grab a few add-ons that definitely make this product even better.

Reviewers across the web have noted how powerful this particular model is, making it excellent for large campers and significantly longer use times.

If you plan on camping when the temperature is very low very often, not just at night, this could be a great pick.

Pros

  • Digital controller
  • Great for colder weather
  • Well-known manufacturer

Cons

  • Poor translated instructions

2. Triclicks 8kW

💰 Price: $129

Consumption: 0.30 liters/h

The Triclicks 8kW diesel heater is a newbie in the world of camper van diesel heaters, but it has made quite an impression since its debut. While the overall quality of the heater is nowhere near the S2-D2L since it’s your run-of-the-mill diesel heater from China, it’s a surprisingly durable diesel heater.

It’s also not as powerful as the S2-D2L but it can easily warm up your RV if you’re camping in temperatures ranging from -40℃ to 50℃.

The reason the Triclicks 8kW heater is our #2 pick is due to the extremely cheap price tag coming in at just $160 on Amazon. That’s almost 10 times cheaper than the S2-D2L and it’s surely not 10 times less powerful or outputs 10 times more noise.

If you want a heater that’ll last you a lifetime, this probably isn’t it. But if you want a super cheap and consistent diesel heater that WORKS, then give the Triclicks a shot!

Pros

  • Very cheap at $160
  • Very easy to install
  • Surprisingly efficient

Cons

  • Not exactly German quality
  • Won’t last a lifetime
  • Isn’t completely silent

3. Vevor 5kW

💰 Price: $134

Consumption: 0.51 liters/h

Vevor is a lesser-known Chinese brand that has become quite popular on platforms like Amazon. Their 5kW model is one of this company’s more popular diesel heater kits, namely due to its low price and included accessories.

It’s performance is much like the Triclicks 8kW but the overall fuel consumption is much higher. It uses an average of 0.51 liters diesel per hour which is more than 3 times as much as the Webasto that we’re covering below.

If you want a complete all-in-one diesel heater for a fraction of the price of major brands, then the Vevor is definitely worth looking into. Just don’t expect too much from a $134 heater.

Pros

  • Decent performance
  • Extremely cheap

Cons

  • High fuel consumption
  • Flimsy quality

4. Webasto Air Top 2000 STC

💰 Price: $1.300

Consumption: 0.12 liters/h

One of my favorite diesel heaters currently on the market is the Webasto Air Top 2000 STC diesel heater. I’ve used it in a 21 foot long van and it’s almost overkill! On Webasto’s own website, they mention:

Air heaters are particularly suited for sailing and motor boats of up to 45 feet.

With other words, you can easily heat up almost ANY RV. But doesn’t it make a ton of noise then? Nope. It’s surprisingly silent despite it running on full power!

Coming in at a little over $1.400 it’s definitely not a cheap diesel heater. That’s also why it’s so far down the list. Most people don’t have $1.300 to spend on a diesel heater.

If you really want a diesel heater that’s notoriously quiet and very fuel efficient, then the Webasto Air Top 2000 STC should be your #1 pick. I’ve tried a ton of diesel heaters the last few years and I really haven’t found anything quieter than this one.

Pros

  • Very quiet
  • Popular with great ratings
  • Extremely efficient

Cons

  • Unknown altitude limitations
  • Sells out quickly
  • Very expensive

5. Webasto Air Top EVO 40

💰 Price: $1.800

Consumption: 0.18 liters/h

The Webasto Air Top EVO 40 is in almost all categories the big brother to the 2000 STC. It can output more heat, costs a lot more, and uses a bit more fuel.

The reason it’s sitting at #5, below the 2000 STC, is because of the steep price tag and increased fuel consumption. If you’re camping in a van, then the Air Top EVO 40 is definitely overkill. I would only looking into buying it if you’re camping in a larger camper.

However, it’s an extremely reliable, German diesel heater that’s definitely capable of heating up your van without using too much fuel.

Pros

  • Ideal for larger campers
  • Built-in altitude sensor
  • German engineering

Cons

  • Very expensive
  • Rarely available

Final thoughts

When buying a diesel heater for your van, there are a couple of things you want to keep in mind:

  • How much does it cost? (duuh…)
  • Is it capable of heating the entire van?
  • Does it work in lower temperatures?
  • Will it fit in my van?
  • How much fuel does it use?

If you keep these 5 questions in mind when looking for a diesel heater, you really can’t go wrong. One thing to note is that the cheap diesel heaters (namely the Triclicks and Vevor) on this list is a hit or miss (big-time). You can either be lucky and get one that works perfectly for years or be unlucky and get one that breaks the first time you turn it on.
