How Much Diesel Does A Webasto Heater Use?

Modern Webasto parking heaters, of course, are designed to use less fuel. At full power, they only need 0.6 liters per hour, or 0.3 liters in 30 minutes. However, because the engine is not started cold, the increased fuel usage is practically offset.

What is the average amount of diesel used by a Webasto?

What is the fuel consumption of a Webasto heater per hour? Of course, the amount of fuel consumed is highly dependent on the amount of heat required and the type of heater used. A heater requires 100 ml diesel per hour and kW as a very basic and noncommittal proportion. Please refer to the heater’s technical specs for more information.

What is the average amount of diesel used by a diesel heater?

What is the fuel consumption of a diesel heater? The total fuel consumption every hour is totally dependent on a lot of factors such as the heater model, ambient temperature, and even altitude, but you’ll normally be looking at 100ml per Kw.

What is the fuel consumption of a Webasto bunk heater?

Inside the vehicle, air heaters are mounted on the floor or another mounting mechanism. To install, make sure the heater fuel type and operating voltage match the fuel type and operating voltage of your car. You’ll need about the same amount of floor space as a shoe box, plus an unobstructed area below the floor for the heater’s exterior connections. The heater can be fitted as a stand-alone unit or within cabinets, as long as the cabin air is correctly ducted into and out of it and is never obstructed.

Do you still have a portable heater with you? It may be time to upgrade and install a built-in heater because they have more functions and capabilities than a portable heater, including the ability to tap into a fuel source, the ability to run for longer periods of time, and, most importantly, the combustion process is separate from the interior air, preventing moisture from accumulating inside the cabin.

In addition, a built-in heater takes up less room, which is important for logistical movers and tourists. A portable heater takes up more room, and the surfaces around the heater become hot, posing a fire hazard.

  • Webasto gets its fuel straight from your car. This is advantageous since you do not need to transport a separate tank, which would take up valuable cargo space.
  • When compared to propane, gas and diesel have a higher energy density, therefore they use less fuel to heat your van.
  • Highly fuel efficient, it can run for up to 22 hours on a single gallon of gas, compared to.8 gallons per hour for an idle engine.
  • In comparison to propane, gasoline and diesel are dirtier fuels. As a result, carbon can accumulate over time.
  • It’s not easy to get rid of carbon. The entire unit must be disassembled, cleaned, and reassembled.
  • When operating at high elevations for long periods of time, the CO2 concentration of the exhaust may need to be adjusted by the dealer.

This is what you should consider when deciding between propane and gas/diesel heaters:

  • Carrying or installing a propane tank (energy source) for a heater involves a lot of labor and expensive space.
  • Because propane has a lower energy density, running the heater for an extended period of time will become pricey.
  • Because of the open heating elements, portable propane heaters can be a serious fire hazard.

Is it expensive to run a diesel heater?

You may heat your camper or RV with a variety of fuel sources, but diesel heaters are generally regarded the best heaters for van living. This is due to the fact that diesel is both inexpensive and safe to use.

What is the fuel consumption of a 2kW diesel heater?

The volume of fuel pumped is usually between 0,020 ml and 0,023 ml, and this information can be found on the pump or in the manual. To calculate the consumption for each power mode, multiply the volume of the pump by 60 for consumption per minute or 360 for consumption per hour.

The consumption of a standard 2kW Chinese diesel heater per minute and per hour for each mode is shown in this table.

How long will a diesel heater run on a gallon or a liter of fuel?

You can quickly calculate how long you can operate your heater on a full tank or how long you can keep fuel in the tank by using the consumption table above, and adjust accordingly. Most diesel heaters come with 10L or 2.64-gallon tanks, which last a long time due to their low usage. It’s simple to figure out how long a gallon of petrol will last in any power mode.

In Low power mode, a 2kW diesel heater will run for 26,25 hours on a gallon of gasoline and around 7 hours on a liter of fuel. Here’s a table that compares the consumption of a 2kW Chinese diesel heater in all power modes.

How long will a diesel heater run on a gallon of fuel?

Heat is one of the hot topics of all van builds (pun intended) (pun intended). Whether you’re chasing snow or not, you will likely find yourself in some pretty chilly overnight temperatures. That’s exactly where the Espar Airtronic D2 Heater comes in taking you from shivery nights of sleep to comfortable home-like warmth.

While Espar makes several diesel heaters, the Espar Airtronic D2 Heater is most popular for van conversions. I have experience installing and living with the Espar D2 as my main heat source (in conjunction with excellent insulation), which I talk about in detail inside my van build guide.

While there are many different heat source options for your van, let’s dive into what we love about this one.

Single Fuel Source

One of the most important criteria in determining whether or not to use a Diesel Heater in your van is the desire to have a single fuel source. The Espar D2 Heater is a wonderful option if you don’t want to carry around extra gas to power a heater.

You won’t run out of fuel

When using your van’s single fuel source to also heat it, one of your biggest concerns is running out of fuel.

Thankfully, the Espar Heater is built to prevent this from happening. The Espar Heater pickup will no longer pull diesel out once the fuel tank is a bit less than a quarter tank.

Dry fuel source

This diesel heater, unlike other heat sources, is a dry fuel source, which means it won’t allow moisture to build up within the van.

Because propane is a damp heat source, condensation in the van is a possibility.


This heater has an automatic temperature control system and comes with a hand-held controller that you can plug into your control panel. It’s as simple as pressing a button to turn the heat on or off and regulate the temperature.

Service Availability

Because the Espar Heater is so ubiquitous, it can easily be serviced by any truck mechanic or repair facility. When you’re on the road and want some extra peace of mind, this is a plus.

It’s a DIY Project

While the components and instructions within the box may seem overwhelming, installing the Espar Heater is a simple task. You can easily save $1000-$2000 and use that money for other elements of the project with a little effort, patience, and study.

Check out our Van Build Guide if you need some more assistance with the installation process.

It doesn’t take up any usable space

The heater is usually situated beneath the van’s driver or passenger seat. It doesn’t take up any usable inside room, unlike other propane and portable heaters, which is always a high requirement for van occupants.

Takes less fuel to heat your van

Because diesel has a higher energy density than propane, it will need less fuel to heat your vehicle. This heater can run for 24 hours on a single gallon of diesel, which is extremely efficient.


The Espar’s instructions are clearly intended for professionals. We believe the Espar installation can be a terrific DIY effort based on our experience. It is, however, more time consuming to install than some other heat source options.

Annual Cleaning and Maintenance

Due to carbon accumulation, diesel heaters need to be cleaned once a year. Also, if you don’t use the heater for a long time (for example, a complete summer), it will start up dirty, so clean it out before using it for the first time.

Espar D2 vs D4

You might be asking why the Espar D2 is preferred over the Espar D4. In short, the Espar D4 is overpowered for the vehicle, and it won’t be used at high boost levels very often. This implies that the extra gasoline that goes into the heater is not burned. That extra fuel will collect inside the heater, clogging it up with soot and unburned fuel, causing a slew of problems and requiring a lot of maintenance.

The D2 runs at high output on a regular basis, keeping the heater nice and toasty and ready to burn the fuel cleanly.

Looking to camp at high altitudes?

Upgrade to the high altitude kit if you plan on doing any camping at altitudes of 5,000 feet or higher. As you gain altitude, the concentration of oxygen decreases, resulting in a fuel-to-oxygen ratio that is overly high in fuel, producing problems with your Espar D2.

Final word of advice

Because the Espar is a combustion heater, we strongly advise you to install a Carbon Monoxide detector to alert you to any pollutants that may enter the vehicle.

A diesel heater consumes how many amp hours?

It consumes about 10 amps of power when it first starts up. The burner takes around 3 minutes to heat up. Our diesel air heaters draw between 0.55 and 0.85 amps when the flame is established, making them extremely energy efficient. The initial starter time will be longer as the system primes if there is no diesel in the fuel line for a new start up or if the fuel tank has been run dry.
