AIR 2D Heater and 9 L Water Heater

Enjoy comfort, autonomy, and versatility with this complete AUTOTERM Air 2D + PUNDMANN 9L kit. It combines a powerful diesel heater with a high-capacity water heater, perfect for converted vans, trucks, vans, motorhomes, or boats up to 10 meters.

The Autoterm Air 2D heater, known for its reliability, efficiently distributes warm air. Thanks to the included bypass, this flow can also heat your water via the Pundmann 9-liter water heater. The latter can also be used independently, with its 12V, 24V, or 230V electric resistance.

This kit is ideal for anyone looking for an integrated, compact heating + hot water solution compliant with VASP.
