The Espar AS3-D2L diesel heater is the classic way to heat the interior of your van using fuel from your main diesel tank. This kit includes everything you need to install the Espar in a standard RV or campervan and will operate effectively up to ~ 13,000 ft. in elevation with the included altitude sensor.

Not all Espar kits are built the same. Cheap knock-off versions are known to have issues with the wiring harness and don't always include all of the parts you need. These units are genuine Eberspacher heaters with high-quality wiring harnesses from our US Supplier. They come with a complete one-year warranty and technical support, unlike other versions.

Upgrades From S2-B2L: 

• Now works at higher elevations, up to 13,000ft. 
• New flame tube, burns fuel more efficiently. 
• Glow pin screen has been removed, less maintenance. 
• New graphics to identify which unit you have. 

Product Specs:

• Fuel type: Gasoline (Diesel units available)
