Diesel heaters

Diesel heaters (also called parking heaters or air heaters) burn a small amount of diesel in a sealed chamber and blow the warm air into your living space, while the exhaust goes outside. They use very little fuel, usually about 0.03–0.13 gal (0.1–0.5 L) per hour, and very little electricity once running. They do need a short burst of extra power at startup to heat the glow plug. All-in-one models have the fuel tank and controls built in and sit outside or in a toolbox, while split models are installed permanently. Budget models are often advertised as "8kW", but their real output is usually much lower, so don't rely on the rated number. If you camp at high altitude, look for altitude adjustment. Webasto, Eberspächer (Espar) and Autoterm (Planar) make the premium heaters; budget brands like Vevor, Hcalory and Sunster cost far less, but quality varies more. The exhaust must always be sealed and routed outside, and you should always use a carbon monoxide detector with one.
