Is 8 kW enough for a van or truck cab?

Yes. 8 kW is high for this class; most van and cab heaters run 2 to 5 kW. Expect fast warm-up, and plan to run it on a lower setting once the space is warm.

Will it work in a 24V truck?

Yes. It accepts 12-24V systems, so it suits both 12V cars and vans and 24V trucks and equipment.

How much diesel does it use overnight?

The maker says about 1 gallon covers a full night and that at least 90% of the fuel is used. Real use depends on the setting and outside temperature.

Does it need venting?

Yes. Diesel air heaters burn fuel and must exhaust outside through the supplied pipe. Route the exhaust away from windows, doors and intake air.

What comes in the box?

The listing describes the heater, remote control and LCD display. Check the package contents for the exhaust pipe, fuel line, pump and mounting parts before installing.

Can I use it indoors?

Only with proper exhaust venting to the outside. Never run it in a closed space without routing the exhaust out.

Our take on the KFFKFF 8 kW Diesel Air Heater

The KFFKFF 8 kW is a diesel air heater for cars, trucks, RVs, boats and work spaces. It runs on 12-24V power, so it suits both light vehicles and heavier 24V rigs. The maker claims at least 90% fuel use and a full night of warmth from about a gallon of diesel. A remote with a 98 ft range and an LCD panel handle settings. Against the common 2 kW to 5 kW Chinese diesel heaters, the 8 kW rating is high for the class, and buyers of this type usually report strong heat but noisy pumps and uneven build quality.

About the KFFKFF 8 kW Diesel Air Heater

This is an 8 kW diesel air heater for cars, trucks, boats, RVs, excavators and indoor spaces. It runs on a 12-24V DC power system and produces a steady flow of warm air. The heater uses at least 90% of the diesel it consumes, and 1 gallon of diesel can provide heat through a whole night.

A remote control with a range of 98 ft adjusts the settings, and an LCD screen shows the controls. Temperature has 6 adjustable levels. Operating noise is 75 dB or less.

The exhaust pipe must point outward so carbon monoxide stays out of the interior. Install the intake pipe and muffler horizontally with minimal bending, and keep them separate from the exhaust pipe.
