This 8kW diesel air heater's vertical, upright design makes it easy to tuck into a corner of the garage or store standing up in an RV, and it runs on DC12-24V with two wiring options - an adapter or a direct DC12V connection - for use with vehicle batteries, wall outlets, or portable power stations. A built-in CO alarm continuously monitors carbon monoxide, sounding an alert at 300 ppm and shutting the heater down automatically at 500 ppm, backed up by a leak-proof fuel cap, fuel level indicator, and overheat protection. The cast aluminum body and ceramic igniter heat quickly with combustion efficiency of 90% or higher, burning about 1 gallon of diesel to keep a space warm through the night. A premium muffler and fuel pump keep operating noise at 75 dB or below, and you can run the whole system from the Bluetooth app, the included remote, or the built-in display panel. At 18.7 pounds with a large carrying handle, it moves easily between the garage, cabin, and vehicle.
