Heating solutions for
light commercial vehicles

Engine-independent heat for the front, cargo area, engine and traction batteries 

Our heating solutions for fuel and electrically powered vans provide temperatures that keep drivers and cargo warm even when stationary. They also ensure that the van starts reliably, even at very low outside temperatures. Another plus: this saves fuel and emissions, and the heaters extend the range in electric vehicles. Contact our installation partners in your area to clarify the options for retrofitting in your specific vehicle, which you can find using our dealer search.

Heating solutions for fuel-powered vans 

A Webasto water heater is recommended for heating the front area before driving off and defrosting the windows. It is integrated into the vehicle's coolant circuit. Once the heater has warmed the coolant, the heat is transferred to the air, which then flows into the interior via the vehicle fan. In addition, the heaters can preheat the vehicle engine so that it starts more easily, even at the lowest ambient temperatures, and requires less fuel. Webasto water heaters for vans are available with 3 to 9 kW heat output.

 

Webasto Air-Top models, on the other hand, heat the air directly and distribute it in the front area or in the load compartment. Where the warm air flows out can be flexibly selected during installation. Our appliances deliver between 2 and 5.5 kW of heating power. They can be used as parking heaters, but also heat while driving.

Webasto offers a wide range of applications and parts for individual original equipment and retrofit solutions for both air and water heaters.

 

They can be integrated into 12 and 24 V environments and also heat with alternative fuels such as HVO and GtL. There are variants with Arctic Start function for particularly cold environments down to -40 degrees Celsius and automatic altitude adjustment up to 5,500 m.

 

Integrated heat exchangers from webasto are suitable for using residual engine heat to heat the vehicle interior. Various models offer heating outputs from 3.3 to 13 kW.

Heating solutions for electrically powered vans

Webasto high-voltage heaters (HVH) with heating outputs between 5 and 12 kW are available with 400 and 800 V. Thanks to their highly efficient stratified heating technology, they convert direct current into heat with virtually no loss.

Uniformed courier at wheel of a delivery van showcasing Webasto vehicle solutions that enhance last-mile logistics, cargo security and efficiency.

All models are ISO 21434-compliant, but differ in terms of voltage, communication interfaces and service life. Thanks to their extremely compact design, the HVHs require very little installation space. They heat both the interior and the traction batteries, thereby extending their service life and range.

 

For electric vans that are in use for many hours, need to be available at all times or are used to transport people, our Range Plus retrofit solution provides reliable heat without limiting the range of the batteries. It consists of a fuel-powered air heater and a tank for diesel or HVO.
