Hmmm...you are probably right, but it boils me with heat 1 second 
after I start the car.  I don't know how it could do that in cold 
weather without an electric element - I think it would take a moment 
for the heat to get going if it was from water cooling exchange.

Anyhow, my point was that none of my American or Japanese cars have 
had gasoline fired heaters like the Eberspacher.
