Famous Brand Defa Universal Emergency Fast Charger Warmup Heater 12A 20A 35A Wireless Lead Acid Electric Vehicle EV Charger Battery with CE

In order to evaluate which engine heater concept is most efficient, comprehensive tests were conducted on Euro 6 diesel engines.

Key Conclusions:

• 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 heaters.
• Contact heaters increase engine block temperature approximately 20-25°C more than coolant heaters.
• Coolant heaters increase cylinder head temperature by approximately 30°C more than contact heaters.
• Energy Efficiency: A 300W contact heater typically uses 42% less energy compared to a 550W coolant heater.
• Cold Start: WarmUp systems allow you to start driving with 22°C in the cabin, whereas a standard cold start takes 18 minutes to reach 20°C.
