Van Diesel Heaters: Best Options for Vanlife

Key takeaways

In the past, the idea of selling your home and living in a van would’ve been waved off as insane. Nowadays, more and more people are recognizing the unique advantages of van life. In 2019, over 140,000 people lived in recreational vehicles — and that number is only increasing. Whether you’re embracing van life to escape stress or you’re using it as a way to travel, it’s important to be prepared for all situations, including unpleasant weather conditions.

If you’re wondering how to keep your van warm during the winter, you’re not alone. Unlike traditional homes, most vans don’t come equipped with internal HVAC systems — you’ll have to purchase a separate heating system. While there are different options for heating a van, we recommend a diesel heater. Here’s everything you need to know about choosing, installing and using a diesel heater for van life.

Once you’ve got your campervan properly insulated, the next step is selecting a van life heater. From propane and electric heaters to gasoline and diesel, there’s no shortage of options to choose from. To help you understand the different heaters, we’ve assembled a brief guide that gives their respective pros and cons.

Electric Heater for Van Life

Many people keep electric heaters in their homes to supplement their HVAC systems during winter. This concept can also be applied to van life. Electric van heaters share many of the advantages of standard electric heaters: they’re inexpensive, easy to set up and heat rooms quickly. However, there are some disadvantages to these tools. Generally, electric van heaters:

  • Require high levels of power
  • Rely on a power supply
  • Have limited heating abilities

Not only do electric heaters require a large amount of power to work, but they also need to stay connected to a 12 volt power inverter. While they can work well if you park your van at a campground overnight, they’re not the most sustainable option if you hope to stay on the road.

It’s also worth noting that electric van heaters are usually not as powerful as propane or diesel heaters. Thus, they’re best for people who travel in their vans every now and then as a recreational activity.

Propane Heater for Van Life

As the name suggests, a propane van heater uses propane — a type of gas stored as a liquid — to supply heat. The main advantage of propane heaters is their energy-efficient properties. Propane van heaters emit lower levels of CO2 than diesel and gasoline heaters, which is better for the environment. However, there are a few downsides to propane heaters, such as:

  • Difficult installation: Before using a propane heater, you need to install a tank. Due to the weight of these tanks, the installation process may require significant planning.
  • Inconvenience: While a gasoline heater for van life simply taps into the vehicle’s fuel tank, a propane heater above 20 pounds in weight needs to be refueled at propane refilling stations.
  • Higher costs: Not only is propane more expensive than traditional gasoline or diesel, but it also requires more fuel to heat your van. This translates to increased costs.

While propane tanks may be more beneficial to the environment, the inconvenience of visiting propane refilling stations and the high costs associated with the fuel can make it burdensome to use.

Radiant Heat

Radiant heat is a rising technology that involves supplying heat directly through your vans floor. While this heating system is usually found in homes, there are companies that have brought the technology into the van world (such as Van Life Tech Radiant Heat).

Radiant heat is one of the most convenient heating options out there. In addition to requiring little to no maintenance, it’s energy-efficient and provides uniform heat. However, this option is rather expensive — it can cost anywhere from $6 to $20 per square foot. It also elevates the floor, which takes away some of the space in your van.

Diesel Fuel Heater for Van Life

A diesel heater operates with the help of diesel, a fuel that’s usually used to support large vehicles like vans and trucks. One of the best parts about owning a diesel heater for van life is that it can connect to the fuel tank that’s already attached to your vehicle.

While you can use gasoline to heat your van, there are several advantages to using diesel instead. These include:

  • Stronger heating abilities
  • Enhanced temperature control
  • Fewer CO2 emissions
  • High accessibility
  • No license required for installation

According to the Universal Technical Institute, diesel fuel is about 20% more thermally efficient than gasoline. Its powerful heating components, simple installation requirements, relatively low costs and accessibility make diesel fuel one of the most popular options for van owners.

How Does A Diesel Heater Work In A Campervan?

The task of heating a van in winter is made much easier with the help of a diesel heater. Most people use a diesel night heater for vans, which creates hot air without requiring you to turn on your vehicle or use excessive amounts of fuel. Here’s how they work:

  • Air is drawn into the heater through a pipe, which connects to the exterior of the van.
  • The air enters a combustion chamber, where it mixes with diesel fuel.
  • The air and diesel ignite and enter a heat exchanger, which causes air to heat through circulation.
  • Warm air is released into the van through a duct .
  • Excess gases are removed through an exhaust system.

A diesel heater can use anywhere between 0.1 and 0.5 liters of fuel per hour, making it an economical solution for powering your van’s heat.

What Size Diesel Heater Do I Need For My Van?

There’s no “one-size-fits-all” when it comes to diesel heaters. Some people might use a small van heater that provides 2kW (kilowatts) of power, while others may rely on an 8kW device. As discussed in our diesel heater size article, the main considerations are the following:

  • Your budget
  • The size of your van
  • The area you’re in

Of course, the first thing you need to consider is your budget — stronger heaters tend to cost more, so keep that in mind as you review your options. However, the most important factor is the size of your van. If you have a small sprinter van or a compact cargo van, then your heating needs will be minimal. Conversely, if you own a large home on wheels, then you’ll need a higher amount of heat to thoroughly warm the area.

Unsure what constitutes a small, medium or large-sized van? As a general rule of thumb, small vans are between 7 and 9 feet in length, while medium-sized vans can be anywhere from 9 to 12 feet. Anything bigger is classified as a large camper van. 2kW heaters are usually sufficient for small and medium-sized vans, while a 5kW or 8kW heater might be better suited for larger vans.

Finally, take into account the area you are living in or the areas where you plan to travel. If you’re visiting locations with extremely low temperatures, your heating needs will be higher than someone staying in an area with moderate temperatures.

How Do I Install A Diesel Heater In A Van?

Once you’ve chosen your desired diesel heater, the next step is to install it. The precise location you place your heater plays a role in how the heat is distributed through the van. Installation options for a diesel van heater include:

  • Under the passenger seat
  • The center
  • Near the back

If you’re wondering what your Transit or Sprinter van heater options are, try looking under the passenger seat — most vans have excess room here. Not only does putting your heater here minimize the space it consumes, but it’s also ideal if most of your amenities are located near the front of the van.

While most people store their diesel van heaters near the front, some camper van floor plans are not designed for this setup. If the interior of your van is long (length-wise), or if there is a large amount of space between the front and back, then you might want to install your diesel heater near the center. Similarly, if most of your materials are near the back of the van, that might be a better installation spot.

How Much Does It Cost to Install A Van Diesel Heater?

When installing a diesel heater, it’s important to follow instructions to a tee. In the best-case scenario, an improperly installed diesel heater for van life will offer insufficient heating. In the worst-case scenario, it can be a fire hazard.

Various Tools for Diesel Heater Van Installation

Due to the potential dangers of a wrongful installation, you may want to leave the process in the hands of professionals. On average, the cost of a professional van diesel heater installation can range anywhere between $700 and $1,500. The exact cost usually depends on a few different factors, such as:

  • The type of heater
  • The type of van
  • The location you want it installed in

Some heaters and vans are more difficult to work with than others, which can increase installation costs. For example, take cargo vans — when determining how to heat a cargo van, the installation team will need to take into account your storage items, which can consume extra time.

Some van owners might wonder whether they can install their heaters underneath the van itself to conserve space. While most people opt to place their heaters in the interior of the van to optimize the heat distribution, you can choose to mount your heater underneath your van if you’d like.

Are Diesel Van Heater Fumes Dangerous?

One of the biggest concerns when installing a diesel van heater is fumes. Inhaling any type of fumes within an enclosed space can be dangerous to your health and increase the likelihood of a fire. Fortunately, by implementing basic safety measures, it’s completely safe to use a diesel heaters in your van. These include:

  • Automatic shutdown feature: If the temperature gets higher than a certain level, the heater will automatically shut down to prevent overheating or fires.
  • Electrical charge: During the combustion process, diesel heaters rely on a device known as an electrical charge glow pin. This is safer than an exposed flame, which would increase the risk of fire.
  • Exhaust vent: Diesel heaters get rid of unpleasant gases using an exhaust vent, which transports the gases to the van’s exterior. Moreover, due to the high quality of diesel fuel, the exhaust gases are largely odorless.

Thanks to the mechanisms inherent in diesel van heaters, you can rest assured that you’re not breathing in any dangerous gases.

If you plan on living extensively on the road, then you’ll probably want to setup a shower in your campervan. While some people might be able to manage with cold water, most of us prefer hot water for our showers, which begs the question: how do I heat water in my van?

To get warm water, most people use a 12-volt water heater for vans. If you have a diesel heater, it can also be used to power your camper van water heater — this is achieved by adding adaptors to the heat exchangers, which lets the diesel heater release hot air and increase the water temperature.

Are Chinese Diesel Heaters Worth It?

The average Chinese diesel heater costs around $125 to $300, which is substantially cheaper than a heater made in the US. While this can be a huge relief on your wallet, Chinese diesel heaters often get a bad reputation in the following categories:

  • Durability
  • Safety
  • Accessibility

The main issue with Chinese diesel heaters is that they can be difficult to fix if something goes wrong. Because the heaters are made in China, it can take time to get in contact with the support team or retrieve a replacement part. This is especially problematic because Chinese diesel heaters are more likely to break down than ones made in the US.
