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.

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.
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.
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.
This catalogue has been designed to help you in defining
a complete solution for each motor home and caravan.
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:

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.
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.
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

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
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:
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.

Integrated heaters
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.

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.

Advantages

The advantages of a Webasto water heater
■■ Supply of warmth via the air outlets in the dash board
(Thermo Top C Motorcaravan)
■■ Cabin heating and optional pre-heating of the engine
■■ Heating power up to 5.2 kW or up to 9 kW
■■ Less emissions due to engine pre-heating
■■ Quiet-running, low noise operation
■■ Diesel-fueled, directly fed from the tank
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.

Thermo Top C Motorcaravan
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.
■■ 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 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.
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.

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.
