Winter is almost here and soon it's time to scrape ice again and drive away. And maybe every morning. The fact is, it is not exactly a pleasure to get into an ice-cold car in winter with extremely low outside temperatures after the windows have been painstakingly scraped free. And running out quickly and letting the engine warm up isn't a good idea either. Here there is a fine of 80 euros! Either one helps here so-called Engine heater for connection to a socket on the Parking, The Carport or in the Garage, or alternatively the luxury variant in the form of a Stationary heating system. It ensures cozy warmth in the vehicle interior and, depending on the version, even preheats the engine. Modern systems can even be activated some time before the start of the journey using an app or a remote control.

This is how the installation works!

There are different systems on the market. One of the most common systems works similar to a normal home heating system powered by fuel oil. Fuel is burned from the tank of the vehicle, generating heat. It is a fully enclosed system in which the combustion of the fuel takes place. A heat exchanger heats the cooling water, as it does when the engine is running. However, the heat is generated in this case without running engine by the heater. The effect is the same as when the engine is warming up. By heating the cooling water and switching on the vehicle fan warm air passes through the heating nozzles in the interior of the vehicle. A pleasant side effect is that the engine is pre-heated with, which contributes not insignificantly to fuel saving and engine preservation. The exhaust gases produced during combustion are discharged to the outside like in an internal combustion engine. For this reason, a working according to this principle auxiliary heater should not be operated in the garage.

For installation and operation of a parking heater

The installation of a heater is anything but a breeze. He should necessarily take place in a specialist workshop. The technology of such a heater is connected to safety-related elements in the vehicle such as the fuel tank. Usually also adjustments to the vehicle electronics must be made to integrate the control of the heater in this. The operation is relatively easy. The auxiliary heater can be started for example via a timer or an app. Of course, the system takes some time to bring the cooling water and thus also the heating system to an appropriate temperature, especially at extremely low outside temperatures.

Which is especially important

An intact battery must be installed in the vehicle so that the auxiliary heating and the vehicle engine can start at any time. It is also important to charge them sufficiently over long journeys. If daily trips are too short, this can quickly become a problem. The battery may not be sufficiently charged here while driving. It is also very important that the fuel tank is not run empty, otherwise the heater's fuel system must be vented. An old wood stove as an alternative? You can do it, but shouldn't get a license and the operation is also quite cumbersome ^^. What do you have to pay attention to if the vehicle is to be made fit for the dark season? The most important information can be found in our winter check.

You can plan a full working day for proper installation. Sometimes even more. Parts of the paneling in the engine compartment have to be removed, new connections are required in the tank Battery and I baked the Fan Heaters connect. A special control unit is connected to the on-board electronics so that everything works. The manufacturers therefore choose to do the assembly themselves discouraged.

  1. Thank you for the contribution to the parking heater. My uncle had to change his parking heater and decided to use an electric parking heater. It's good to know that the car's battery is responsible for the simple start-up of the heating and you should therefore pay attention to a functioning battery.
