How Webasto Dual Top ST Heaters Work

Webasto Dual Top ST is an integrated air- and water heating system that operates efficiently and cost-effectively.

When the unit is switched on, the dosing pump feeds fuel from the vehicle fuel tank to the heater. Here the fuel is automatically ignited by means of a glow plug. In the combustion chamber, the flame heats up the heat exchanger. The unit takes air in from the outside for combustion purposes and the combusted exhaust is discharged to the outside.

During heating, the integrated fan takes in the cold air from inside of the vehicle and routes it through the unit. As the air flows through the heat exchanger, it heats up and is then distributed through the outlets back into the vehicle. The connected hot air ducting now spreads the air evenly throughout the vehicle interior. A temperature sensor constantly measures the interior temperature and automatically adapts the heating power output by adjusting the amount and temperature of air passing through the unit. For heating the vehicle evenly, Dual Top ST has two outlets delivering the heated air.

The advantage here is that the vehicle can be heated from two directions, guaranteeing perfect warm air distribution.

All Dual Top ST heaters have a boiler where water is being heated up to 40 ° or 70 °C. The Dual Top ST also features a separate antifreeze mode that can be selected at the control panel and which ensures that the boiler and cabin temperatures remain above freezing point. If the water temperature falls below 6 °C, the automatic drain function ensures that water is emptied from the boiler – even if the heating system is switched off. In addition, the boiler can be drained manually directly at the control panel.

On a campsite with access to electricity, Dual Top ST versions with electrical coils can run either additionally or exclusively on 230 V electricity.
