Which vehicles can be equipped with a Parking Heater?

A Parking Heater can be installed in just about any vehicle. Request your no-obligation offer from a dealer near you. 


How long does it take a Parking Heater to warm up the engine and the vehicle interior?

That depends large on the ambient air temperature and the size of the vehicle. A heating period of between 20 and 30 minutes is however normally sufficient to turn uncomfortable minus temperatures into comfortable interior warmth.


How is the Parking Heater activated?

Activation of the Parking Heater is achieved either by a radio remote control (Telestart T91 and Telestart T100 HTM), by a mobile telephone (Thermo Call) or by using the programmable digital timer, which installed in the car. Test our innovative control elements.


Why does a Parking Heater increase safety?

According to the statistics most accidents in winter occur within the first 15 minutes of driving off. The reason for this is the limited vision and the increased reaction times brought about by the low temperatures. A parking heater offers greater safety and comfort on cold and wet days and in winter. Added advantages: Both the engine and the environment are placed under less strain.


How much fuel does a Parking Heater consume?

Modern Webasto Parking Heaters are optimised for low fuel consumption. They only require an average of 0.6 l / h at full power – that’s just 0.3 l over 30 minutes. But because there is no cold start his increase in fuel consumption is balanced out.


What do you have to pay attention to when a vehicle is operated with biodiesel?

Up to 20 % biodiesel is mixed with conventional Diesel. This mixture is suitable for Parking Heaters. The Parking Heater also functions with E10 biofuel (fuel containing 10 % ethanol). Vegetable oil is unsuitable.


What does the parking ventilation function do? What advantages does this offer?

Thermo Top Parking Heaters are beneficial in the summer months due to the parking ventilation function. The parking ventilation function can be switched on 20-30 minutes before your departure. Fresh air from outside is blown into the car’s interior, thereby avoiding the build-up of heat. To utilise this function your Parking Heater model must be equipped with the appropriate function.


Parking Heaters also need electricity. What are the implications for the vehicle’s electrical system?

Thermo Top parking heaters also exhibit an optimum electricity consumption / performance ratio. However, the rule of thumb still applies: heating time should not exceed driving time.


Does fitting a Parking Heater affect the vehicles’ exhaust emission classification?

No. Exhaust emissions are significantly reduced when the engine is pre-warmed.


Can Parking Heaters also be removed and refitted in other vehicles?

Yes. But for technical and economic reasons this does not normally make sense because a parking heater increases the resale value of a car. In addition, the parts that are removed are not usually sufficient to fit the same parking heater into another car. Vehicle-specific components or a complete installation kit are required. The possibility of a conversion should be checked by a Technician.


Do Parking Heaters require maintenance?

No. However we do recommend that the heater unit be checked by a technician before the cold weather period sets in. The Parking Heater should also be switched on once a year for 10 minutes, with cold engine and lowest heat. For more maintenance instructions please look in your Parking Heater user manual.


Must a Parking Heater be tested and certified?

Each new model is tested and certified. Webasto Parking Heaters are now supplied with an ”EC type-approval certificate“. Following professional installation and the fixing of the type-approval mark onto the vehicle’s type plate this certificate must be stamped and signed. The completed EC type-approval certificate must be filled out by your Webasto Dealer and has to be kept in the vehicle.


Does the Parking Heater react automatically to a specific coolant temperature?

Yes! Once the maximum temperature is reached the unit operates in fuel-saving partial load mode or it goes into standby.


What is an auxiliary heater?

Modern direct injection Diesel engines are so efficient that they do not produce enough excess heat to run the vehicle’s heating system. Diesel vehicles are therefore frequently fitted with an auxiliary heater to ensure a comfortable temperature is reached in the passenger compartment during the journey.


If a car already has an auxiliary heater fitted, is it possible to upgrade it to a Parking Heater? If so, how?

With the aid of an upgrade kit, you can turn this auxiliary heater into a fully fledged Parking Heater. This solution costs far less than a completely new Parking Heater.


My car already has air conditioning. Can I still have a Parking Heater installed?

In most vehicles there is no problem with this installation. Depending on the heating and air-conditioning system installed in the vehicle ex factory, adjustments must be made to the climate control operating component before leaving the vehicle . You can obtain more detailed information from the on-board literature or the user notifications in the installation documentation. 


What is the difference between the Thermo Top Evo 5 and the Thermo Top Evo 5+?

Both models heat with 5.0 kW power but the heat is released faster with the Thermo Top Evo 5+. The Thermo Top Evo 5+ optimises the coolant circulation and therefore the air flow inside the cabin is increased of up to 30%.
