WEBASTO HELP & ADVICE
Choose a heater, identify a controller or find the correct manual.
Start with your model and the details of your installation.
CHOOSING A HEATER
Air heaters warm the living space through ducting. Water heaters heat a coolant circuit that can supply compatible radiators, heat exchangers or a calorifier. Compare the system around your vehicle or boat, rather than choosing by output alone.
Compare air heaters →DOCUMENTS & IDENTIFICATION
Read the exact model, voltage and fuel type from the identification plate. Similar Air Top and Thermo Top names can refer to different heater generations. Check the application and document version before using an installation or workshop guide.
Find your Webasto manual →CONTROLLERS & TIMERS
A controller must match the heater version, communication protocol and wiring. Compare rotary controls, MultiControl, UniControl and ThermoConnect, then check the relevant controller documents. Butler Technik can help identify the required controller and adapter.
Explore controller compatibility →FAULTS & SERVICE
Note the heater model, controller display and any fault code before making an enquiry. Use the model library to find the relevant fault-code or workshop document, and speak to Butler Technik about troubleshooting, parts or servicing.
