A portable diesel heater puts the heater, fuel tank and controls in one carry case. Set it up next to a tent, ice fishing shelter, cabin or garage, run the warm-air duct inside and connect it to a 12V battery or power supply. Karlesk portable heaters deliver 5 to 8 kW of dry heat for camping, hunting, workshops and job sites.

Always route the exhaust outdoors and use a CO detector.
