Compact, efficient heating for vehicles and small spaces — the KFFKFF 5-8KW diesel air heater delivers dependable warmth with flexible wiring and user-friendly controls. It includes two wiring choices (a 110V Adapter and a DC12V T-shaped plug external wiring) so you can use US standard sockets, DV12/24V vehicle batteries or outdoor storage batteries. The plug-and-play setup makes it easy to swap wiring depending on the vehicle or location — ideal for cars, RVs, trucks, tractors, garages, cabins and camping. Heating performance and economy: Power range 5-8kw with a heating efficiency of ≥90%. Low fuel consumption means the unit uses only 1 GAL of diesel per night to continuously heat a large area of 215ft²/20㎡. Controls and comfort: Two control methods are provided — a long-distance remote control (98ft/30m) for one-click preheating and a high-definition LCD display for on-unit adjustments. Built-in intelligent thermostat control enables temperature settings between 46.4~96.8℉/8~36℃ to prevent interior cold, exterior frost and window fogging. Cold-start capability and quiet operation: The heater and oil pump operate reliably from -40℉ to 104℉/-40℃ to 40℃, ensuring stable startups in low-temperature environments. A high-quality muffler and sound-optimized design keep noise at or below ≤75dB for restful sleep in RVs or quiet camping. Safety and installation: The unit has passed rigorous safety checks and includes built-in protections for overheating (≥536℉/280℃), short circuit, overcurrent, overvoltage and reverse connection. Professional installation is recommended and the exhaust must be routed to the exterior.
