Evaluation of engine heater efficiency based on Euro 6 diesel engine testing:

• A contact heater is most efficient for preheating the engine block and oil.
• Contact heaters increase engine oil temperature approximately 30-35°C more than coolant element heaters.
• Contact heaters increase engine block temperature approximately 20-25°C more than coolant heaters.
• A coolant heater increases cylinder head temperature approximately 30°C more than a contact heater.
• Using a coolant heater results in cabin temperatures 3-5°C higher during the first 16 minutes of driving.
• Both contact and coolant heaters reduce regulated emissions and fuel consumption at similar levels (less than 2% variation).
• A contact heater (300W) uses 42% less energy compared to a coolant heater (550W).
• With WarmUp installed, you start the drive with 22°C in the cabin compared to a standard cold start.
• Contact heaters ensure the evaporation of diesel in the system for reliable work in cold conditions.
