If you’ve ever entered a car that was already warm on a freezing winter morning, you’ve likely experienced the magic of Webasto or another parking heater system. Popular in colder regions, these systems preheat your vehicle without starting the engine, offering both comfort and performance benefits.
But what exactly is Webasto? How does it work? And is it worth installing in your car?
What Is Webasto?
Webasto is a German company known for producing high-quality auxiliary heating systems for vehicles — both OEM-installed and aftermarket. Over time, the term “Webasto” has become a catch-all phrase for parking heaters, much like “Xerox” for copiers or “Velcro” for hook-and-loop fasteners.
There are two main types of Webasto systems:
-
Air heaters – warm the cabin directly
-
Water heaters – preheat the engine coolant, which then circulates and warms both the engine and the interior via the existing climate system
How Does a Parking Heater Work?
A parking heater is typically installed in the engine bay and connected to the car’s fuel system, coolant system, and electrical system. It operates independently from the engine and works like this:
-
Ignition via timer, remote, or app
-
Fuel is drawn from the car’s tank to the heater
-
Combustion begins inside the unit, generating heat
-
Heat is transferred to either air (in air heaters) or engine coolant (in water heaters)
-
In water systems, the car’s interior fan activates, warming the cabin
-
The engine is also preheated, reducing cold-start stress
These systems usually consume minimal fuel (around 0.2–0.5 liters per hour) and draw some battery power, which is why they’re typically set to run for a limited time (10–60 minutes).
Benefits of a Webasto or Parking Heater
-
Instant comfort – no more shivering while waiting for the car to warm up
-
Engine longevity – preheated oil flows better, reducing wear during cold starts
-
Reduced emissions – warm starts mean cleaner combustion
-
Defrosted windows – no more scraping ice from the windshield
-
More efficient warm-up – faster than relying solely on engine heat
Is It Only for Diesel Cars?
Not at all. While diesel vehicles benefit greatly from parking heaters (due to their slower warm-up times), Webasto systems are available for gasoline-powered cars too. They’re also widely used in RVs, trucks, boats, and even electric vehicles, with specialized electric heater versions.
Control Options
Modern Webasto systems can be controlled via:
-
Built-in timer
-
Remote key fob
-
Smartphone app with GPS/scheduling features (e.g., Webasto ThermoConnect)
Cost and Installation
Installing a Webasto system typically costs:
-
$1,000 to $2,500, depending on vehicle, model, and installer
-
Installation takes 4–8 hours and should be done by a certified technician
While the price may seem high, many users say it quickly pays off in saved time, reduced fuel usage (from not idling the engine), and increased engine life.
Is It Worth It?
If you live in an area with cold winters, commute daily, or want to protect your vehicle long-term, a parking heater is one of the most valuable comfort upgrades you can install. It transforms the winter driving experience from frustrating to seamless.
Final Thoughts
A Webasto heater is much more than a luxury — it’s a practical solution for winter discomfort and engine protection. Whether you’re trying to skip windshield scraping or reduce engine wear, this silent helper in your engine bay can make a big difference in how you experience cold weather driving.
Once you’ve tried it, you may never want to drive another winter without it.
