The Best Sprinter Conversion Van Diesel Heaters

Have a new decked-out conversion that you’re trying to finally take for a spin?

While most people may associate road trips with the summer, there’s no bad time of year to rough it a little and live out of your van while traveling. That is, of course, if you know how to travel, and if you make sure that your van is properly heated.

Sleeping in your cold van with poor insulation will be a miserable experience, especially if you’re road-tripping during the winter months. But if you have a good diesel heater, you’ll feel nice and toasty while you sleep in your big new Sprinter conversion van. All of a sudden roughing it won’t be so rough.

That’s why we’re making this list of the best diesel heaters for your Sprinter vans – so that you can live in the lap of luxury while you cruise across the country taking in the sights.

Carry on reading to see our full list of the best Sprinter conversion van diesel heaters, followed by a recap breaking down what makes each product on our list stand out. Or jump straight to our number #1 pick on Amazon here.

What Should You Look For in a Sprinter Conversion Van Diesel Heater?

If you’re just getting started decking out your new Sprinter conversion van, then you might not know what to look for in your heater. After all, you’re used to just using the heater built into your van. But if you want to really get the job done and be nice and toasty no matter where you are at any time of the year, it’s better to use a diesel heater.

We’re going to quickly breakdown the criteria we used to find the best diesel heaters so that you can feel like an expert in no time. Plus, this will help you understand our thought process throughout this list, and you’ll be able to conduct your own further research if you so desire.

Criteria #1: Heat – I think this one is pretty obvious. A heater that doesn’t heat is pretty clearly useless. Of course, we’re not just talking about whether or not a product works, but whether or not it actually works well. I hate being cold, and I can tell you from personal experience that it’s just about the most frustrating experience imaginable to go out and buy a new heater for the winter and find out that it just doesn’t quite get the job done. We want to make sure you don’t wake up in the middle of the night shivering, so we’re only going to include the best heaters that will make you feel nice and toasty while you’re getting ready for bed.

Criteria #2: Convenience – “Convenience” may feel like a pretty broad term, but I’m referring to two pretty specific traits that I consider to be part of the broader concept of convenience. Those traits are size and noise. A heater that takes up the entire back of your converter conversion van is going to get really annoying really quickly, and the same can be said for a heater that makes a racket every night.

We don’t want you to have to tip-toe and hop around the back of your fan in the morning, and we also don’t want you to feel like you have a snoring roommate every night. That’s why we’re going to look for heaters that are both small and quiet. Unfortunately, it may be hard to find such a diesel heater that’s also powerful enough to get the job done, but that’s what we’re aiming for.

Criteria #3: Fuel Consumption – You’re going to have to spend a fair amount of money on a diesel heater for your conversion van, and we really don’t want to add unnecessary expenses on top of that. The fuel itself can really add up, so we want to get a heater that’s as fuel-efficient as possible so the amount of money you spend over time doesn’t end up completely eclipsing the overhead price of your heater. Besides, it’s always nice to reduce our carbon footprint as much as possible. You’re burning through enough fuel with your actual van. Let’s try to add to that as little as possible.

Criteria #4: Price – We’re not here to make you spend a ton of money for no reason. Meeting this criterion is less about being cheap and more about justifying your price. We’d rather buy an expensive product that’s cheaper than it should be than waste money on a cheaper product that isn’t worth the money and that will just break on you or not perform well. Unfortunately, as we mentioned before, a decent diesel heater is inevitably going to cost a pretty penny. Of course, we can make sure that your new heater is as reasonably priced as possible, and that every dollar you spend is actually reflective of the quality of the product you’re receiving.

Here’s How We’ve Determined the Best Sprinter Conversion Van Diesel Heaters

We measured the specs of the top products on the market against our listed criteria to see how they held up and if they’re worth buying. We then checked customer reviews, blog posts, and “best sprinter conversion van diesel heaters” articles to see if the products on our list performed as advertised. We’re also going to be on the lookout for any extra features that didn’t fall under our listed criteria, and we’ll make sure to include a wide variety of products from different price ranges. This way, everyone can find exactly what they’re looking for at the price they’re looking for.

And without further ado, here is our list – tailored to your specific needs – of the best Sprinter conversion van diesel heaters.

#1: SuperFastRacing 8KW 12V Diesel Air Heater Tank (Best Value – All-Purpose)

Get the SuperFastRacing 8KW 12V Diesel Air Heater Tank at Amazon

Our list starts off with the SuperFastRacing 8KW 12V Diesel Air Heater Tank. The first feature that I need to talk about with this Sprinter conversion van diesel heater is the trait that gives this heater’s manufacturer its name. SuperFastRacing takes the “superfast” part of their name very seriously and, depending on the size of your van, the SuperFastRacing 8KW 12V Diesel Air Heater Tank can heat up your vehicle in just 5 to 15 minutes. No more time sitting around shivering in your van while you wait for things to heat up so you can comfortably go to sleep.

To follow up on that quick-heating technology, this air heater will help your camper van warm up no matter how cold it is outside, as the SuperFastRacing 8KW 12V Diesel Air Heater Tank can work at temperatures as low as -40 degrees Celsius.

It’s equipped with a 12-volt battery that can pump out 8,000 watts of heat, so you don’t need to worry about this diesel heater not getting the job done.

None of these specs or features address what may be my favorite part of the SuperFastRacing 8KW 12V Diesel Air Heater Tank. Our best diesel heater for your camper fan boasts a simple and intuitive LCD display that you’ll be sure to understand the second you look at it. This goes a long way towards giving you a controlled experience, as you don’t have to eyeball any physical knobs, and you can know exactly how hot your van is about to get.

The SuperFastRacing 8KW 12V Diesel Air Heater Tank is pretty critically acclaimed. It’s one of the most popular diesel heaters on Amazon, so you can rest easy that you’re not risking your money on some unknown quality.

This SuperFastRacing product comes equipped with a 10-liter fuel tank that can be used for about 36 hours. This all comes in at an amazingly cheap price, and you can shave some precious dollars off the price by opting for a physical knob interface or by going with 5k watts instead of 8k watts. That makes the SuperFastRacing 8KW 12V Diesel Air Heater Tank the best value available on the market, and that’s why it was an easy choice to be our best Sprinter conversion van diesel heater.

As a quick reminder, I’m using “convenient” with the definition we established in the “criteria” section of this article, that is to say, the best combination of quiet and small. So if you appreciate some peace and quiet and you want to make the most out of a smaller amount of space, then the Labwork Parts 8KW 12V Diesel Air Heater is right up your alley.

Another more affordable option, the fourth air heater on our list is the best option for anyone who wants to stay as green as possible.

While it’s incredibly fuel-efficient, the No. 32 12V 5KW Diesel Air Heater has a 5-liter fuel tank, which is smaller than the other products on our list. So while you’ll be consuming less fuel over time, you may be filling up your gas tank at the same rate, which may create the illusion that you’re not saving money or the environment.
