Our take on the KFFKFF 12V Diesel Air Heater

The KFFKFF 12V Diesel Air Heater is a parking heater for cars, RVs, trucks and boats, rated to warm roughly 215 to 269 square feet. Its selling points are three ways to control it (Bluetooth app up to 98 ft, a 32 ft remote and an LCD panel) and automatic altitude adjustment up to 18,045 ft, which most budget diesel heaters lack. It is a 12V unit, so it suits vehicles and off-grid cabins with a 12V supply rather than home mains wiring. Against cheaper Chinese diesel heaters it stands out on altitude compensation and control range; the trade-offs are the installation work and the usual diesel-heater concerns of pump noise and exhaust routing.

Questions and answers

Will it work at high altitude?
Yes. It has automatic altitude adjustment that compensates up to 18,045 ft (5,500 m), so the fuel-air mix stays consistent on mountain trips.
How do I control it?
Three ways: a Bluetooth app from up to 98 ft (30 m), a 32 ft (10 m) remote control, and the LCD panel on the unit.
What size space can it heat?
The manufacturer rates it for about 215 to 269 square feet (20 to 25 square meters), which covers most campervan, truck cab and small boat cabins.
Does it run on 12V or 24V?
This is the 12V version. Check your vehicle or battery system is 12V before installing; 24V setups need a different unit or a converter.
Can I preheat the vehicle before I get in?
Yes. The app and remote let you start it remotely, so the cab or cabin is warm before you arrive.
What is included?
The kit ships with the heater unit, LCD panel, remote control and installation instructions; you supply the fuel tank, ducting and mounting for your vehicle.
