4 good reasons to use electrical preheating in your car

The frozen side mirror of a car.

Getting into a warm car on a cold morning is heavenly thing, but increased comfort is not the only benefit you get with an electrical preheating system. Here are the four best reasons to get one now!

1. Increased comfort & safety

Any choice between an aggressively cold and a pleasantly preheated car is easy. Ducking out of the cold and into welcoming warmth provides a much improved start to the day. Not having to spend precious morning minutes furiously scraping stubborn ice of the windows is another welcome relief. With windows already free of ice and fog, you’re sure to become a safer and more relaxed driver.

2. Preheating reduces toxic emissions.

A cold start causes even new cars to release the same amount of toxic emissions in the first 30 seconds as a heated car emits in nearly 190 miles of driving. This alarming revelation comes from a study conducted by scientists at Berkeley, Carnegie Mellon and the University of California. Increased emissions from cold starts makes the air we breathe decidedly unhealthy, especially for those of us who live in densely populated areas. For anyone up to date on climate science, the unfortunate implications for the future should be clear.

By using an electrical preheating system, you can minimize your own negative impact on the local and global environment. Studies have show that electrical preheating can reduce emissions by up to 71%! (Read more)

3. A preheated car consumes less fuel

Who says environmentalism and the economy are at odds? Reducing fuel consumption is a double benefit. A preheated car uses less fuel to get the engine to its ideal temperature and you won’t have to use fuel consuming heating functions like seat heaters and defrosters.

4. Preheating reduces wear on the engine

Cold starting a car is a bit like forcing it straight from bed and into a 100 meter dash – you might not notice at once, but harm is likely to occur. A cold engine has cold oil and cold oil is thicker and less able to effectively lubricate the engine. That’s not ideal. Your engine as a whole also reacts to the cold and is much happier when it’s sufficiently warm.

How to avoid cold starts

With the negative effects of cold starts out in the open, the next question becomes how to avoid them. If you’re the lucky owner of a garage – just keep using it. If you’re between garages right now however, an electric preheating system is the way to go.

What is electrical preheating?

A complete electrical preheating system consists for for main components. All these components contribute to reducing toxic emissions, fuel consumption and wear on the engine, in addition to making each day a easier and more comfortable for the user.

Interior Heater

The interior heater warms the air in the driver and passenger compartment, making it more comfortable while reducing the need for seat heaters, defrosters and similar heating functions. When these aren’t used, the engine uses less fuel to drive the generator. A warm interior also melts ice on the windows and helps prevent fogging.



Engine Heater

The engine heater preheats the engine and motor oil, ensuring better lubrication and reduced friction. This reduces wear and fuel consumption. We create custom engine heaters for nearly all car models on the market. Hose heaters and contact heaters are equally efficient at heating the engine. Note! The engine heater must be order separately.



Battery Charger

The battery charger keeps your battery fully charged. This ensures that your car will have the power necessary to start, even in the coldest weather. It also prolongs battery life. Furthermore, preventing a complete discharge helps maintain settings in the car’s electrical and computer systems.


DEFA AppControl System

A user friendly app on your phone helps you control and automate heating according to your habits and preferences, as well as according the conditions where you live. The system automatically figures out when to start heating in order to have our car ready when you’re scheduled to leave. It also regulates heating down when the engine and interior is ready, so you won’t use more power than necessary.
