Air Heaters for the RV Market 

Diesel powered air heaters: 

Webasto air heaters provide continuous heating power output via 

stepless modulation, ensuring constant temperatures. The heater 

operates quietly and consumes very little electrical power and fuel. 

The air heater can be used as a stand-alone heating solution or as 

a add-on system to existing heating solutions. Therefore Webasto 

offers heaters with different power, ranging from 2 kW up to 5.5 kW 

heating capacity. 

All Webasto Air Top heaters can be either mounted outside, in the 

double-floor or inside the vehicle. For outside mounting Webasto 

offers an additional cover to protect the heater.

Webasto enables RV enthusiasts to enjoy a new way of motor home holidays. 

Most of today’s RV engines are diesel powered. So why burden oneself with 

the dependence on an additional fuel source? With a diesel powered heater 

users can easily enjoy several days of autonomy. Refilling diesel is worldwide 

assured, as t is a standard everywhere and available around the clock.

High-output, compact and quiet, the heateris ideally suited for the most rigorous 

requirements. It can be upgraded with the new multi mode control panel to offer 

additional operation modes depending on individual heating requirements. 

Depicted here is an underfloor heater operating in recirculated air mode 

with four outlets. The entrance area is heated indirectly by the intake line. 

In top-bankvehicles the upper sleeping area should be heated with a 

separate outlet. The same is recommended for the garage. 

In vehicles consisting of several separate areas a sufficient number of 

outlets must be installed for a uniform distribution of heat. The air intake 

is at a central location in the vehicle.

Our mission 

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 

■■ 

All Webasto heaters can be mounted outside the vehicle. 

This significantly increases the total storage space inside the 

motorhome. 

Less weight 

■■ 

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. 

Increased fuel autonomy 

■■ 

Diesel fuel is uniform worldwide and available 24/7 all year 

long with precise monitoring of fuel supplies via fuel-gauge. 

■■ 

No extensive procurement of LPG gas bottles in foreign 

countries necessary. 

■■ 

No adapter for foreign LPG gas bottle connectors necessary. 

■■ 

Heating whilst driving in any country without the need of 

purchasing additional security valves. 

Perfect climate on board 

■■ 

Thanks to the stepless power regulation 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. 

This catalogue has been designed to help you in defining 

a complete solution for each motor home and caravan.

Introduction to autonomous camping 

Innovative technology for more freedom – 

heating with diesel 

Live in total autonomy – heat and drive with diesel. Besides the 

fact that you can gain more space inside the vehicle or increase 

your payload when heating with diesel, it provides you with 

more freedom and autonomy. Exactly what you need when you 

are on holiday and want to relax rather than wonder where to 

get new gas. 

By heating with diesel you can benefit from: 

■■ 

24/7 availability at different fuel stations throughout the world 

■■ 

Carrying less LPG gas bottles leads to an increase of payload 

■■ 

Less hassle to find supplies in foreign countries 

■■ 

Reduced physical handling of heavy LPG gas bottles 

■■ 

Heating whilst driving without any further expenses 

Diesel heating is not that new anymore to the motor home 

market as Webasto has been providing sophisticated solutions 

for years. Heating with the fuel provided by the vehicle fuel tank 

is the smartest way to make use of the existing fuel on board. 

This enables to reduce the overall gas consumption e.g. in winter 

by more than 80%. You can get diesel fuel anywhere nearly 

24/7 whereas finding proper LPG gas supplies might end up in 

some annoying hassle also due to the different gas bottles and 

adaptors used throughout Europe. 

10


Webasto – market leader when it comes 

to diesel heating 

Every year, Webasto produces more than 1 million fuel 

fired heaters for all kinds of markets. Quality, reliability and 

performance have always been our top priorities. We test 

our systems regularly in our own climate testing chamber, 

exposing them to varied and extreme temperatures and 

weather conditions. This enables us to adapt them perfectly 

to your motor home needs.

The advantages of a RV-specific heater 

scope of delivery 

Why should I choose a RV-specific scope of delivery? 

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: 

Easier to handle RV scopes of delivery 

1 4

■■ 

Plug & Play System: Ready to install 

■■ 

One order number for a complete kit 

■■ 

Reduction of purchasing and logistics efforts 

■■ 

New organization of kits for faster and easier 

installation 

Very low noise applications 

■■ 

Specific RV dosing pumps: Operate at a very low 

noise level 

■■ 

Exhaust and combustion air silencers reduce 

significantly outside noise emissions, ensuring 

peaceful nights for customers and their neighbours 

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 inside 

the vehicle 

■■ 

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 

5 

External temperature sensor is obligatory 

for RV applications 

It is standard in all RV scopes of delivery and provides 

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 


on Air Top Evo and Dual Top Evo heaters 

■■ 

Integrated altitude sensor guarantees optimum heat 

output at high altitudes 

■■ 

Automatic measurement and adjustment of heater 

operation at high altitudes with low air pressure and 

lower oxygen content

How Webasto Dual Top Evo heaters work 

Webasto Dual Top Evo 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 spread the air evenly 

throughout the vehicle interior. A temperature sensor constantly 

measures the interior temperature and adapts the heating 

level by automatically adjusting the amount and temperature of 

air passing through the unit. For heating the vehicle evenly, 

Dual Top Evo 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 Evo heaters have an 11-litre-capacity boiler where 

water is being heated up to 40 °or 70 °C. The Dual Top Evo 

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 Evo versions 

with electrical coils can run either additionally or exclusively on 

electricity. 

17


Dual Top Evo 

Dual Top Evo – Warm air and water 

The Webasto Dual Top Evo 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. 

What‘s new on the 

Webasto Dual Top Evo: 

■■ 

Higher efficiency thanks to 

improved motors 

■■ 

Already certified according 

to ECE norm 

■■ 

Modern, digital product 

documentation 

■■ 

Extended, three-year warranty 

The Dual Top Evo as well as the air intake can be positioned in the back. 

The heated air can be distributed directly through several outlets inside the 

compartment. 

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. 

Mounting the air intake in a central area will provide an even air 

circulation throughout the interior. In addition both heater outlets are 

used in a similar way to distribute the heated air flow evenly in the cabin.

How Webasto air 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 

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.

Available as a complete installation 


A simple air distribution system is recommended in small recreational 

vehicles. Heated air outlets and intake positioned as far as possible from 

each other ensure that the air is distributed uniformly. 

The air intake system also heats the garage it operates in. An aperture 

returning air to the living space is then obligatory. 

In large vehicles the Air Top 2000 ST is used as an additional heater for the 

front section for generating pleasant temperatures in this inadequately 

insulated area as well.

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 

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, an internal circulation pump feeds the water 

glycol mixture through the unit. As the water glycol mixture 

flows through the heat exchanger, it heats up. In the connected 

water circulation system, heat exchangers then transfer the 

energy to the interior and the engine. 


Once the vehicle interior or engine has warmed up, the heat 

requirement is reduced and the water temperature continues to 

rise. At a pre-set temperature threshold, the unit reduces output 

at this moment or goes into standby mode. 

The heating procedure automatically restarts when the water 

temperature drops below a certain level. The unit thus adapts the 

heat output automatically to the heat requirement. 

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 Thermo Top C Motorcaravan is the combination of the popular Webasto parking 

heater adapted to the specific needs of RV enthusiasts. It allows unlimited heating and 

offers the double function of heating the cabin and preheating the engine. 

The switch is turned to the symbol for preheating the engine 

(and the cabin): The water circuit is heated up to a state which 

opens the thermostat valve. The engine is heated up by the hot 

water. The effect can even be increased by reducing the air outlets 

to a minimum. 



■■ 

Heating power up to 5.2 kW 

■■ 

More comfort in the front of 

the vehicle thanks to warmth 

supplied via the air outlets in 

the dash board 

■■ 

Cabin heating and optional 

pre-heating of the engine 

■■ 


■■ 


The switch is turned to the symbol cabin heating only: The hot water 

circulates in the vehicle’s water circuit, thus heating up the cabin. 

The circuit only heats up to a point that the valve is not opened. 

All available heat is transferred via the dashboard to the driver’s cabin.

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.

How the diesel cooker works 

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.

Diesel Cooker X 100 

Diesel Cooker X 100 – freedom and autonomy 

The Webasto Diesel Cooker X 100 is the perfect solution for independent travellers and 

individuals who intend to have only one fuel on board. 

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 andone 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.
