A mission aiming for optimal convenience: 

rely on the fuel you already have on board. 

Webasto has always prioritised the fuel of the vehicle as the main fuel used. This strategy does not work against 

LPG gas – it has been working properly for decades now – however Webasto believes in a more logical solution which 

also provides: 

More space inside 

n All Webasto heaters can be mounted outside the vehicle. This significantly increases the total storage space inside 

the motorhome. 

Less weight 

n In winter 88.33 % of the LPG gas carried with the RV is needed for heating. With Webasto products you can 

downsize your LPG stock to one single 5 kg bottle and gain up to 35 kg for additional load inside the vehicle. 

Perfect climate on board 

n Thanks to the stepless power regulation to within 1 W (unique feature on the market), Webasto heaters manage 

to maintain a stable cabin temperature with a hysteresis lower than 0.4 °C. This creates greater passenger comfort. 

Increased fuel autonomy 

n Diesel fuel is uniform worldwide and available 24 / 7 all year long with precise monitoring of fuel supplies via 

fuel-gauge. 

n No extensive procurement of LPG gas bottles in foreign countries necessary. 

n No adapter for foreign LPG gas bottle connectors necessary. 

n Heating whilst driving in any country without the need of purchasing additional security valves. 

This catalogue has been designed to help you in defining 

a complete solution for each motorhome.

Having absolutely satisfied customers in the long term, that is the objective of our RV scopes of delivery. Therefore we have 

significant differences between the heaters and applications in the RV market compared to other markets. These differences 

are illustrated below:

■ Combustion air intake silencers: to also reduce disturbing noises outside the vehicle 

Thermo 90 ST 

Use as main heater 

Use as additional heater alongside existing unit (e.g. LPG gas) 

Use as additional heater or water heater 

Differences to Webasto heaters designed for other markets 

Air heaters designed for other markets start to idle when the target temperature is reached: 

■ The side-effect: 

End users feel a cold air flow from the outlets, which makes them feel uncomfortable 

■ The solution: 

RV specific heaters are programmed differently. The idling effect is deactivated in all heaters 

inside the RV scopes of delivery to provide the best comfort for the end user 

External temperature sensor is obligatory for RV applications 

– it is standard in all RV scopes of delivery and provides following additional advantages: 

■ Target temperature inside is reached more accurately 

■ External sensor delivers application relevant data to the heater which acts according to the needs 

of RV customers by maintaining the temperature without disturbing air flow (air re-circulation) 

■ In addition, the power consumption is reduced significantly 

Automatic Altitude Adjustment on Air Top and Dual Top heaters 

■ Integrated altitude sensor guarantees optimum heat output at high altitudes 

■ Automatic adjustment of heater operation at high altitudes with low air 

pressure and lower oxygen content

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 spread the air evenly 

throughout the vehicle interior. A temperature sensor constantly 

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.

For the distribution of the hot air in your vehicle you 

need hoses, distributors and outlets. Please configure 

your air distribution system individually. 

Note: Always screw the hot air ducting to the 

outlets at the heater for a safe application! 

Water distribution 

Choose the right components for each vehicle. 

Note: Use adapters (e.g. John Guest/Whale/ASP) 

for all conenctions! 

See page 38 

See page 60 

Extracting heating air from an enclosure like a seat box can reduce the noise 

coming from the heating air ventilator. Especially in vehicles with several 

areas a number of air outlets positioned in different spots ensure an even 

distribution of heated air in the living spaces. 

Dual Top – Warm air 

and water 

The Webasto Dual Top is a multimode 

operation system to provide heating and 

hot water in all seasons. It can be installed 

outside the vehicle to free storage space.

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. If combustion does not occur 

immediately, the unit automatically repeats the start-up 

procedure. In the combustion chamber, a flame is lit which 

heats up the heat exchanger. The unit takes air in from the 

outside for combustion purposes and the combusted exhaust 

air is discharged to the outside. 

During heating, the integrated fan takes in the air to be heated 

through the inlet and feeds it through the unit. As the air flows 

through the heat exchanger, it heats up and is then distributed 

through the outlet. 

The connected hot air pipes now spread the air evenly throughout 

the vehicle interior. Due to the unit’s own separation of the 

combustion cycle from the heat cycle, there is no impairment 

of the quality of the hot air. 

A temperature sensor constantly measures the interior 

temperature and adapts the heating level by automatically 

adjusting the amount of air passing through the unit. In this 

way, the temperature selected by the user is rapidly reached 

and maintained at a constant level. 

After the unit has been switched off, the combustion process 

is terminated in a controlled manner. For this purpose, the unit 

briefly goes into re-run mode to cool itself down. 

It is then immediately ready for restarting.

The advantages of a 

Webasto Water Heater 

The advantages of a 

Webasto water heater: 

n Supply of warmth via the air outlets in the dash board 

(Thermo Top C Motorcaravan) 

n Cabin heating and optional pre-heating of the engine 

n Heating Power up to 5.2 kW or up to 9 kW 

n Less emissions due to engine pre-heating 


n Quiet-running, low noise operation 


The Thermo Top C Motorcaravan 

can also be integrated into the 

existing heating system. 

How Webasto water 

heaters work: 

When the unit is switched on, the dosing pump feeds fuel 

from the vehicle fuel tank to the heater. Here the fuel is

Air Flow Resistance Calculation 

Air Flow Resistance Calculation 

In order to ensure a correct application with correct air ducting system, a continuous main line with openings that cannot 

be closed must be ensured. When branches are used, the lines branching off the main line are not taken into account. 

As a result, the branches can also be designed in a way to be closed. The following table lists several air ducting parts. 

The sum of resistance points must not exceed the maximum number of resistance points for each air heating model.

n Key enabler of autonomous gas free camping 

n Robust, high quality CERAN ® cooking surface 

n Easy to use and to clean 

n Low current and fuel consumption

gas pipe 

Vehicle floor 

Exhaust is channelled outside 

Outside pipe,

Pipe passes through vehicle 

floor, sealed with silicon 

How the Diesel Cooker work: 

The heat generated by the fuel combustion process is transferred 

to the ceramic panel, and the exhaust gases directed out of 

the vehicle through an exhaust gas line inside the cooling air 

line. The vapour content of the exhaust gases therefore do not 

give rise to greater humidity in the vehicle. The diesel cooker’s 

heat output is continuously adjustable. In addition a cooling fan 

in the ventilation box ensures that the temperature does not 

reach a critical limit in the installation area. Hot air is drawn off 

through the cooling air line.

The connection of the cooker to the fuel system 

depends on the vehicle. A basic fuel extractor is part 

of the delivery scope. If you need any additional parts, 

please refer to the fuel section for more information. 

See page 56 

The cooker is operated via a diesel burner which is sourced with fuel out of the 

vehicle’s tank. Warm air, combustion and smells are fed directly outside. The robust, 

high quality Ceran cooking field provides two cooking plates: one for cooking and 

one for heating up food as well as maintaining warmth. Thanks to its compact 

dimensions and flat design, the Webasto Diesel Cooker fits even in the smallest 

kitchen. Another advantage of the Ceran cooking plate: it can be cleaned easily.
