How much area does an 8KW diesel heater heat?

8KW is the largest common size in this class and suits a large van, garage or cabin. Real output depends on insulation and outside temperature, so treat the rating as a ceiling, not a guarantee.

Can it run from a portable power station?

Yes. It accepts DC 12-24V, so a 12V power station or vehicle battery works. Check that the station's DC output can supply the heater's startup draw, which is higher than its running draw.

Is it safe to sleep near it?

It has a CO alarm that alerts at 300 ppm and shuts down at 500 ppm, plus overheat protection. Still route the exhaust outside and keep a vent open, as with any diesel heater.

How much diesel does it use?

About 0.18-0.35 L/h depending on the heat setting. A small tank lasts a night or more at low output.

What controls does it have?

A Bluetooth app, a remote control and a display panel. All three let you change heat settings without reaching the unit.

Does it come with a fuel tank and ducting?

The all-in-one design includes the fuel tank, fuel level indicator and handle. Check the box contents for ducting and mounting parts before installing.

Our take on the 8KW Diesel Air Heater

The AsterOutdoor 8KW is a self-contained diesel air heater for vehicles, garages, cabins and campsites. It runs on DC 12-24V from a battery, outlet or power station and burns 0.18-0.35 L/h of diesel, so it heats a large space without a mains hookup. Its cast aluminum body, ceramic igniter, Bluetooth app, remote and display panel put it ahead of bare-bones Chinese diesel heaters on control and safety. The built-in CO alarm, overheat protection and leak-proof fuel cap are the features budget rivals usually lack.
