Which auxiliary heater is suitable for your car? How economical is the equipment? How to control the device? What to pay attention to while working? We will give answers to these and many other questions - so that you understand everything when choosing the right Eberspächer heater!

Answers on the topic Cost-effectiveness

How much fuel does an auxiliary heater consume?
Eberspächer heaters have high efficiency thanks to optimized flow. For example, Hydronic 4 consumes at full power heating is only about 0.5 liters per hour. Often, only half an hour is enough to heat up the interior and engine. Depending on the external temperature and operating time, the device regulates the heating power and thus reduces consumption. Therefore, our brochures indicate the consumption for 15 minutes at the “High” heating level and for 15 minutes at the “Low” heating stage. In addition, a warm engine reduces fuel consumption during the starting phase.

What is the load of the auxiliary heater on the battery?
Low consumption current A simple rule applies here: heating time = driving time to recharge the battery.

Is it possible to move an auxiliary heater from one car to another?
I guess, yes. For the service station, this is the same as the installation, no problems - provided that the same fuel is used.

The auxiliary heater requires a special service maintenance?
No, no maintenance is required after installation. But the system - like the air conditioner - must be turned on for a short time every month. 10 minutes will be enough.

What is the service life of an autonomous heater?
Autonomous heaters Eberspächer are designed for an average of 3000 hours of operation. This is confirmed by the operation of a large number of trucks, in which our auxiliary heaters are installed as standard and are used daily by drivers during the cold season.

How long is the warranty for new auxiliary heaters?
By law, the end-user period is two years, with the second year for workshop service provided voluntarily by Eberspächer.

Designed for heating car interiors, working equipment cabins and trucks with diesel fuel.

The device connects to on-board network And fuel tank car (it is also possible to work from additional tank). After startup, the system enters cold air from the street, heats it to the desired temperature and delivers it to the salon. Air vent connection can be configured to supply air both from outside and from internal space car. In the latter case, heating will occur faster and with less fuel consumption.

Heaters Eberspacher Airtronic D2 are produced German company Eberspächer, created 150 years ago. At that time, this company was a small family business and was mainly engaged in the production of metal structures. Subsequently, having begun to specialize in equipment for cars, the small company turned into a huge concern. They were the first in the world to create .

Principle of operation

Principle of operation air heater Eberspacher Airtronic D2 (Eberspacher) based on air combustion fuel mixture in the combustion chamber. Wherein hot air enters the cabin using a fan. Thus, it requires the vehicle's electrical system and diesel fuel to operate. All these processes are controlled by a computer built into the heater ().

Eberspacher Airtronic D2 is controlled using a remote control. There is a rotating regulator on it, which sets the required temperature. The position of the regulator is achieved experimentally and depends on the outside temperature, the volume of the heated room and personal preferences. You can also start the heater using a timer ( additional option, is not included in the package and must be purchased separately).
When the Eberspacher Airtronic D2 auxiliary heater is turned on, the control light on the control panel lights up. After 1 minute the fuel supply starts and after a few more minutes the heater reaches maximum number speed and fuel supply.
The Eberspacher Airtronic D2 heater constantly measures the room temperature - if it is higher than the required one, it begins to regulate it. If the temperature in the cabin is higher than the set temperature even at the lowest heating mode, the heater will go into cooling mode for a few minutes, and then either switch to fresh air supply mode or will operate at minimum speed until the next start. If the heater overheats, an emergency shutdown will occur.
