Both require battery power/shore power to operate. The forced air requires that the furnace be left on which means you need LP and 12volt power. Tank heaters keep the tanks warm, but won't do much if anything for pipes, the furnace does.

Many people prefer not to tow with the furnace on (I don't have a problem with it as long as it is shut off prior to refueling the TV) Nothing is nicer than to step into a warm dry trailer on a miserable near freezing day for a quick nap when on the road.

FWIW I am in the process of rebuilding my trailer and am considering adding the 12volt heaters to my tanks as a backup measure.

Airstream never install 12 volt heaters, for the holding tanks.

Hmmmm---we have a tank heater in our 06 Interstate-----it does run off the battery, I believe. Not so?

If you read the specs, some models have hot air tank heating and some have plain tank heaters, here is the quote for the 2009 flying cloud model: "Heated Tanks -12 Volt"
