DEFU 12V 5KW Liquid Diesel Heater For Camper

Fundamentally, a diesel heater, often termed a parking heater, is a self-sufficient fuel-powered heating system. Unlike relying on engine heat, it operates entirely independently with its own dedicated fuel delivery system, combustion chamber, electrical circuits, and sophisticated control unit. This autonomy allows its primary function: preheating both a vehicle's engine block and its cabin interior while the engine remains off. This capability is crucial in cold climates, effectively eliminating the damaging mechanical wear caused by cold starts and providing immediate warmth and comfort for occupants before the journey begins. Parking heaters are categorized by the heating medium (liquid/water circulating coolant or air) and fuel type (diesel or gasoline), each suited to specific applications.

Engineered specifically for the demanding needs of campers, caravans, and motorhomes, this liquid diesel heater represents the pinnacle of efficient and reliable auxiliary heating technology. As a liquid-type system, it integrates seamlessly with your vehicle's coolant circuit. Heated coolant efficiently warms the engine block directly, significantly reducing cold-start stress, while simultaneously providing heat to the vehicle's cabin via its existing heater core and blower system. This dual-action preheating ensures optimal engine protection and passenger comfort from the moment you start your day.

​​Performance Engineered for Extremes:This robust heater delivers a substantial maximum heating output of 5 kilowatts (adjustable down to 2.8KW as needed), providing ample warmth for most recreational vehicles. Engineered for unwavering reliability, it boasts an exceptional operating temperature range from a bone-chilling -40°Cup to +80°C. Its efficiency is a major highlight: fuel consumption is remarkably low at only 0.3-0.6 liters per hour, and electrical draw is minimal . The compact dimensions and lightweight design facilitate flexible installation within the vehicle chassis.
