Which part number for a Van Heater??

[CMH22]

Eberspacher Espar Airtronic S2 D2 L 12V 2.2kW 7500BTU Looking to get one of these for my build. Is there one kit that is better than the other? I noticed there is quite a price difference. Altitude switch is also something it needs to have. Thanks

Hi, some like Heatso as they simplify the wiring harness:

Eberspacher / Espar Airtronic S2 D2L 12V Diesel Sprinter kit

The Espar S2 D2L heater sprinter kit provides perfect performance and durability at a great price, together with everything you need for a quick installation.

There's also a newer version, but it's much more expensive:

Espar Airtronic AS3 D2L 12v 7500BTU Diesel Heater Kit with Pro controller

The Eberspacher D2L S23 diesel heater kit is the most recommended kit for vans on the market. Fuel-efficient and powerful can reliably function in high altitudes

Both have the integrated altitude/elevation sensor, but the newer one works to 18000'.
