This gasoline kit adds Bluetooth control and includes ducting and louvers. It is for gasoline vehicles, including many Ford Transit and Ram ProMaster models. Control the heater from your phone with the SmarTemp app.
The Air Top Pro 25 is Webasto's new air heater for trucks, vans, RVs, buses, and work vehicles. It replaces the Air Top 2000 STC. It gives you more heat and more control in a body that is about the same size.
This is the gasoline kit with the Webasto SmarTemp 3.0 digital controller. Connect it to your phone by Bluetooth and run the heater from the SmarTemp app. It is for gasoline-powered vehicles. Many Ford Transit and Ram ProMaster models run on gasoline and need this version.
It has the widest heat range in its class. In normal use it runs from 2,730 BTU/h (0.8 kW) up to 7,000 BTU/h (2.0 kW). Boost mode gives you 8,500 BTU/h (2.5 kW) and holds it for up to 6 hours. The heater changes its power in small steps to hold the temperature you set. A low minimum output means fewer restarts. That is easier on your battery and quieter at night.
