New Energy Defa Universal Emergency Fast Charger Warmup Heater 12A 20A 35A Wireless Lead Acid Electric Vehicle EV Charger Battery for Car Multicharger System

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.
