Almost all motorists, not counting residents of hot countries, know firsthand how much effort it takes to prepare for a trip in winter, when a car parked on the street is shrouded in frozen snow. Warming up the engine before starting is a mandatory procedure for responsible drivers who care about the heart of their car. The process always takes different times depending on the air temperature and car model, and clearing snow from the windshield is certainly not an easy task. The problem is especially relevant for cold regions of Russia, characterized by a harsh climate, where air temperatures reach -25° C and below, or even drop to -60° C.
Using Webasto in a car.
The weather may be such that you literally have to dig out the car before starting it, and being in the cabin without warming up is the same as being outside. But even in not so harsh winter conditions, comfort in an unheated car is out of the question; the problem is especially acute when there are children. Every driver is familiar with the classic stove in a car, but the efficiency of the equipment is not as impressive as in the case of using modern Webasto heating systems, which allow for a comfortable start in any weather.
First meeting
The Webasto heater is used by both those who live in particularly cold areas and those whose territories are not characterized by constant frosty weather. But even there there are cold nights and days when the car gets very cold and requires quick warming up before setting off.
Start-up is carried out by a remote control; it can be stand-alone or built into a smartphone or other mobile device; the start time for warming up can be set using a timer, which will allow you to warm up the engine and the entire car without leaving home.

Webasto heaters have been produced in Germany since 1935, and the company was created 34 years before the start of production of the device.
The name encrypts the name of the owner of WilhEm BAier STOckdorf - Wilhelm Bayer Sr. Since then, the heaters bear the proud name of the company’s founder.
In addition to heaters, the Webasto company produces Webasto car air conditioners, Webasto lifting roofs, which are moved using an electric drive.
Kinds
There are two ways to heat a car - through antifreeze in the engine and directly through the air in the cabin. Webasto can do both, depending on which model you choose, how and where to install it.
Air autonomous interior heater
This is the simplest and cheapest installation, mounted directly in the cabin. It acts like a heat fan, or can be compared to a hair dryer, only the energy does not come from the network, but is supplied from a tank with liquid fuel.
Of course, only the air that has passed through the heat exchanger enters the cabin, and the exhaust gases are discharged outside. But due to high efficiency and optimization of operation, there are few of them, and they are well cleaned.
Liquid (pre-start)
A more complex device that cuts into the engine cooling line under the hood. It is equipped with its own coolant pump (pump), fuel equipment, and is powered from the car’s tank and from its own battery.
How Webasto works
The Webasto autonomous heater works by warming up the windshield, which is very useful if it is covered with frost. Advanced Webasto models are capable of warming up large interiors.
The Webasto device is small and can be easily placed under the hood, connected to the engine, on-board network, and to the fuel tank.
The payback of the Webasto device is achieved due to the fact that the engine resource increases and fuel consumption for warming up decreases.

Webasto preheaters differ in operating principles: some are based on air heating, others on liquid heating.
Air Webasto
Webasto Air Top is the name of the Webasto device that uses air for heating. It is very convenient in cases where transported goods require a certain temperature regime, which must be maintained during the entire transportation time.
The device resembles a hair dryer in its functioning; the design is simple, so the price is low. Gasoline consumption is about 200 g per hour. Air Top provides warmth in the car when you have to stop for a long time in cold weather or spend the night in the car. A comfortable temperature is created immediately after turning on the air Webasto.

You can place the device directly in the cabin under the seat, but if you need to warm up the engine, its power will no longer be enough. Additional device required.
Liquid Webasto
Liquid Webasto is a liquid-based device that is placed under the hood. Warms up the engine and transfers heat to the cabin. Gasoline consumption - 0.5 liters per hour. A more complex design also leads to a higher cost of the device.
Differences between Webasto and autostart
Nowadays it is absolutely easy to install a security system with an auto-start engine function on any car. The effect will be approximately the same; before the driver and passengers appear, the engine will work for the required time according to the program or command, heat up itself and warm the interior.
It would seem, why then install a relatively expensive autonomous system if there is such a simple solution. Each method has its pros and cons.
Advantages of an alarm system with auto start:
- low price, we can say that there are no additional costs, because the alarm system is still needed to perform security functions;
- no additional hardware complications are required in the already cramped engine compartment, the interior is also not modified, the standard engine and standard heater work;
- the driver does not need to study the operating rules of a rather complex additional device.
But Webasto also has its advantages:
- silent operation, when parking in the yard there is less cause for concern for neighbors;
- significant savings in the vehicle’s engine life; it is known that cold starting of an internal combustion engine is one of the most unpleasant modes of its operation in this regard, and in order to maintain heat it will have to be started often;
- potential savings on fines; strictly speaking, parking with the engine running in residential areas is prohibited;
- due to more efficient fuel consumption, the overall installation is more economical;
- If the engine fails in winter and there is a long wait for help, only the autonomous system will prevent people from freezing in the car.
Somewhat paradoxical, but practical, it would be simultaneous installation of both systems on the car. Then all the advantages will add up, and the disadvantages will disappear, and the costs in terms of long months of winter operation will become very small, this is a very small price to pay for daily comfort and saved health.
Internal structure and purpose of Webasto
The Webasto autonomous heater has the following structure:
The combustion chamber produces thermal energy.
The pump drives the heated liquid along the motor circuit, which in normal situations is cooling.
The heat exchanger is connected to the cooling system.
The entire complex is controlled by an electronic starter.
t-olimp.ru
Webasto operating principle:
- The remote control turns on the “autonomous” system at a distance of up to 1 km, and the timer can start.
- The air entering the combustion chamber forms a fuel-air mixture. The power of the device is from 3 to 5 kW.
- The glow plug ignites it. Energy is released.
- There is heat in the heat exchanger, transferred by antifreeze.
- The pump pumps the mixture through the cooling system circuit: the device’s heat exchanger transfers it to the car’s radiator and to the engine. It turns on the car's heater - this ensures the interior is warmed, and fans are connected to supply air to the car's windows.
- After half an hour, the optimum temperature of the motor is reached - it turns on without difficulty even at - 40 degrees C.
Price
Each driver can look up the cost of equipment including installation on the Internet. However, in practice the price will differ. The same heater on different cars can differ in price significantly.
For example, all liquid heaters are sold without a control unit. That is why the buyer must first select a control. The cheapest is a timer, the remote control is even more expensive, and the most expensive is the GSM module.
The final cost includes the installation price. However, some Webasto models are very simple, so you can install them yourself. To do this, the driver will need instructions.
How to use Webasto
Webasto operates in accordance with the principle that it is turned on when the engine is turned off.
The system starts working from the car battery, so you should monitor its charging. If necessary, the battery is recharged.
It is necessary to monitor the “stove” mode - it should always be in a warm setting, this allows you to warm up the interior.

Control of the device is simple; the operating principle allows the choice of turning on Webasto to be left to the driver:
- The control panel allows you to start operating Webasto at any time. 2 types of remote controls: Webasto Telestart T91 and Webasto Telestart T100 NTM. The second regulates operation based on the temperature in the cabin.
- A timer is the simplest option. We set the time and fixed it in the memory settings. The car will warm up when needed.
- New GSM module (ThermoCall). Installed in modern Webasto device models. Allows you to work via a smartphone anywhere in the world, starts the device regardless of time and distance.
When to start Webasto
- When the temperature dropped to negative values.
- The battery is in a charged state.
- Antifreeze is heated to less than 140 degrees C.
- The alarm is on and the doors are locked.
- The fuel in the tank is more than 25% of the volume.
Operating rules
motorist.guru
For proper operation of Webasto, you should adhere to simple operating rules.
It is necessary to periodically check the operation of the device; such a check should be carried out approximately once every 3 months.
Monitoring fuel quality is also a necessary requirement. Fuel thickening leads to Webasto not turning on.
During winter operation, it is worth turning on the device daily.
In case of problems with startup, Webasto automatically switches off. To check the operation of the device, you need to restart it. If it does not turn on, you need to check other components - the battery or the air duct. It is also worth checking the antifreeze temperature.
Tips for use
Despite the thoughtfulness of the system and high quality, we must remember that the device burns fuel and releases energy in the same way as a car engine:
- the exhaust is toxic, you cannot use autonomous heaters in confined spaces;
- Only the type of fuel specified in the documentation should be used;
- installation of a fire hazardous device must be carried out by a qualified specialist; these are still changes in the design of the car;
- Long periods of downtime should not be allowed, the heater must be started at least once a month, in this it is similar to a car air conditioner;
- We can recommend installing a separate fuel tank for Webasto, this will prevent possible problems with the compatibility of the fuel preferences of the battery and the engine.
With proper use, Webasto lasts a long time and trouble-free, you can expect an approximate service life of 10 years.
Error codes and diagnostics
Diagnostics of a complex electronic device, such as modern Webasto equipment, must be performed by a specialist. However, the nature of the malfunction can be determined by some of the diagnostic codes read.
Codes are obtained either from the control panel display or through the standard K-line diagnostic interface. In the latter case, you can understand the problem much more deeply using the proprietary Webasto diagnostic program taken online.
It will more accurately reveal these and other faults:
- F02 – the flame goes out;
- F03 – supply voltage is outside the permitted range;
- F04 – fuel pump does not work;
- F07 – fan malfunction;
- F09 – spark plug (pin) failure;
- F10 – overheating;
- F14 – temperature sensor failure.
If the control electronics fail, the diagnostics will also not work; you will have to contact a service center. Although formally there is such an error code.
What is Webasto in a car?

The Webasto autonomous heating system provides
- Starting the engine at very low temperatures, including abnormal ones
- Increasing the temperature in the cabin and removing frost from the windows, and this is a safety factor. A driver needs a good view.
- Increased engine wear resistance.
- Reduced emissions, which can be useful especially in the case of diesel.
- The light weight of the device - up to 7 kg - does not make the car more massive and heavy, which can affect its driving performance.
- Safety and long service life of the device.
- Low fuel consumption during warm-up.
- Autonomy of operation, no interference in the design of the machine.
- Ability to turn on while the engine is running.
System advantages
An engine preheater has a number of advantages. Among them are:
- The diesel engine can be started in any frost. But here it is important to use high-quality fuel. Sometimes the causes of malfunctions lie precisely in low-quality fuel.
- There is no need to waste your time warming up the vehicle yourself. The principle of Webasto is that it will do everything on its own.
- For cars, a cold start is very undesirable, which is why many drivers prefer to use Webasto. So, the engine will start much smoother and will last longer for its owner.
Webasto heaters work with different types of engines

Please note!
Models for different engine types vary
Modifications of Webasto equipment function differently, this is due to the fact that the operating principle and methods of fuel supply are different in different engines.
- Gasoline modifications have a lower starting limit than diesel ones. This is due to the structural features of the fuel used
- Accordingly, diesel modifications consume more diesel fuel than gasoline engines. But this is compensated by two factors: the maximum performance of a diesel engine is higher, and the cost of diesel fuel is lower.
Prices with installation (new and used)
The vehicle class and expected operating conditions determine the choice of the appropriate model:
- Thermo Top Evo 4;
- Evo5;
- Evo 5+;
- Thermo 90;
The installation of each of them has its own prices, which can be found by viewing the price list. But for an accurate calculation, it is recommended to contact the sales consultant of the relevant store.
The minimum cost with the installation of a new unit for diesel fuel is from 40 thousand rubles. For gasoline - from 50 thousand rubles. The upper limit is 90 thousand rubles. In other words: from 600 to one and a half thousand dollars. Used earphones are approximately 10-15 thousand cheaper than their new counterpart from each category.
