Webasto heaters use fuel directly from the vehicle's main tank
Webasto heaters are highly fuel-efficient and cost-effective. They are known for being long-lasting and low-maintenance, with fuel consumption depending on the temperature setting. The fuel pump supplies more or less fuel based on the temperature setting selected.
The Webasto Air Top 2000 STC 12V air heater is a community favourite among vanlifers. Available in both petrol and diesel variants, this 2KW heater is ideal for any mid-sized RV or van. The Air Top 2000 STC is fuel-efficient, heating your cabin at altitudes of up to 7,200 feet (2,200 m).
The Webasto Air Top EVO 40 is another popular option, known for its low fuel consumption, versatility, durability, and quiet operation. It is the most popular 4KW Webasto heater and has a range of features that make it ideal for vanlife. With an upgraded control system and optimized combustion, the Air Top EVO 40 works silently and efficiently.
In terms of fuel consumption, the Webasto Air Top EVO 40 has a fuel consumption of 0.04-0.09 gal/h (0.18-0.43 l/h). The Webasto Air Top 2000 STC, on the other hand, has a fuel consumption of 0.026-0.05 gal/h (0.12-0.24 l/h).
Overall, Webasto heaters are a great choice for those looking for a fuel-efficient and cost-effective heating solution for their vehicles.

They can also be powered by a separate fuel tank
Webasto heaters are highly fuel-efficient and can run up to 22 hours on a single gallon of fuel. They can be powered by gasoline, diesel, biodiesel, kerosene, or blends of these fuels. Compared to propane, gasoline, and diesel, propane is a lower energy density fuel that requires a lot of effort and space to install. Propane heaters can also be a fire hazard and cause condensation in the vehicle interior.
Webasto heaters can be powered by a separate fuel tank, which is useful if your vehicle's engine is fuelled by gasoline. A 10L tank can last about 100 hours on low heat settings or 24 hours on maximum heat settings. This can be enough to maintain an internal temperature of 70-75°F when it's 50°F outside, and 60-65°F when it's 30-40°F outside.
The Webasto Air Top 2000 STC 12V air heater is a popular choice among vanlifers. It is a 2KW heater that is ideal for mid-sized RVs or vans, such as the Sprinter or ProMaster. This heater is fuel-efficient, quiet, and can reliably heat your cabin at altitudes up to 7,200 feet (2,200 m).
The Webasto Air Top EVO 40 is another popular option, known for its low fuel consumption, versatility, durability, and quiet operation. It has a heating power of 13,640 BTU (4,000 W) and a fuel consumption rate of 0.04 - 0.09 gal/h (0.18 - 0.43 l/h). This heater also features an integrated altitude sensor that allows it to function reliably at higher altitudes.

They are highly fuel-efficient, running up to 22 hours on a single gallon of fuel
Webasto heaters are highly fuel-efficient, running up to 22 hours on a single gallon of fuel. This is a significant advantage over idling engines, which consume approximately 0.8 gallons per hour. The fuel efficiency of Webasto heaters is due in part to their use of diesel or gasoline, which are more energy-dense than propane. This means that less fuel is required to generate the same amount of heat.
The specific fuel consumption of a Webasto heater will depend on the model and the heat setting. For example, the Webasto Air Top 2000 STC 12V air heater, a popular choice among vanlifers, has a fuel consumption rate of 0.044 gallons/hour on low and 0.3 gallons/hour during initial heat-up. On the other hand, the Webasto Air Top EVO 40, a more powerful 4KW heater, consumes 0.04-0.09 gallons/hour.
The fuel efficiency of Webasto heaters is further enhanced by their ability to regulate temperature. The Webasto Smart Temp Control 3.0BT digital controller allows users to program heat start times and adapt the heating level based on the interior temperature. This ensures that the heater is not using more fuel than necessary to maintain the desired temperature.
In addition to fuel efficiency, Webasto heaters offer several other advantages. They are known for being long-lasting, low-maintenance, and quiet. The compact design of the heaters saves space, and the availability of spare parts makes maintenance and repairs straightforward.
While the fuel efficiency of Webasto heaters is a significant benefit, it is important to consider other factors as well. For example, the use of diesel or gasoline can result in carbon buildup over time, requiring disassembly and cleaning. Additionally, the cost of running a Webasto heater will depend on fuel prices, which can vary by region.

The amount of fuel used depends on the temperature setting
The amount of fuel a Webasto diesel heater uses depends on several factors, including the temperature setting, the size of the vehicle, and the level of insulation. The temperature setting regulates the amount of fuel supplied to the heater, with higher temperatures requiring more fuel.
The Webasto Air Top EVO 40, for example, has a fuel consumption rate of 0.04-0.09 gallons per hour (0.18-0.43 liters per hour). This means that, depending on the temperature setting and other factors, the heater can run for approximately 25-56 hours on a single gallon of fuel.
Another model, the Webasto Air Top 2000 STC, has a fuel consumption rate of 0.026-0.05 gallons per hour (0.12-0.24 liters per hour). This equates to approximately 40-100 hours of operation on a single gallon of fuel, depending on the temperature setting and other factors.
It is worth noting that the Webasto diesel heaters are known for their fuel efficiency. They are designed to optimize combustion and regulate temperature through intelligent controls, ensuring that fuel is used efficiently. Additionally, the heaters can run on diesel, biodiesel, or kerosene, providing flexibility in fuel choice.
When using a Webasto diesel heater, it is important to consider the temperature setting and adjust it according to your needs. By selecting the appropriate temperature, you can optimize fuel efficiency and ensure that your heater runs for an extended period while maintaining a comfortable environment.
