5013913A – Webasto Air Top 2000 STC 12V Diesel Air Heater Kit with Smartemp 3.0 Bluetooth

The Webasto Air Top 2000 STC is one of the most widely used diesel air heaters in North America. Designed for engine-off heating, it provides clean, dry heat directly to the cabin, sleeper, or cargo area without relying on engine operation.

This 12-volt diesel air heater delivers a heating output range from 3,070 BTU to 7,000 BTU (0.9–2.0 kW). Because it heats air directly, warm air is available quickly after startup. In addition, its fuel-efficient design allows for extended runtime—up to approximately 22 hours on one gallon of diesel fuel under moderate load conditions.

The included Smartemp 3.0 Bluetooth controller provides programmable temperature control, diagnostic access, and wireless operation from a mobile device. As a result, users can precisely manage comfort while minimizing fuel and electrical consumption.

Webasto air heaters are extensively used in commercial truck, van, and fleet applications and are recognized as a certified idle-reduction solution, helping reduce fuel usage, engine wear, and emissions.
