The Eberspacher Airtronic S3 D2L diesel powered blown air heater is the ideal solution for fast, efficient and quiet heating of the inside of your Volkswagen T5/ or T6, ensuring it's toasty warm, whatever the weather. No more needing to turn the vehicle's engine on and waiting for it to warm up; you can now have instant hot air at the touch of a button using this standalone heating system, perfect for recovering after outdoor activities and water sports, and providing year-round comfort in your van.

The Airtronic S3 heater is brand new for 2024 and features improved performance compared with the S2 model:

  • 10% better heating performance
  • 17% improved fuel efficiency
  • 12% improved air flow rate
  • 4% weight reduction

The unit is plumbed into the vehicle's fuel tank and uses a metering pump to draw up the fuel, requiring only a low current 12V supply to power the pump, controller and electronics. The system is very efficient, consuming a maximum of 0.27L of diesel per hour and 2.6A from your 12V leisure battery and has under-voltage protection to prevent excessive battery discharge. It can operate in temperatures as low as -40°C and at altitudes up to 3000m, thanks to automatic altitude adjustment, enabling it to work in a very wide range of environments.

This kit contains everything you need to install the S3 D2L heater to the underside of a VW T5 / T6 including Eberspacher's new, programmable Easystart Pro controller that enables you to set heater start and stop times for automatic operation - perfect for waking up to a warm van!
