i examined them and others when i was looking at heaters.  the idea  
of a coolant heater with a separate heater coil and coolant reservoir  
is what i was looking at.  i have seen other do it with the coolant  
heaters.
two minuses for me
first was the heavy money outlay
second was the heavy current draw of both fan and water pump for  
extended use.

for the air heater model it had advantages but the cost was out of my  
budget.  battery draw was much less.  those little fuel pumps draw  
next to nothing.  basically the same fuel pump on the vanagon aux  
heater.

even in their brochure they mention that you should not run it for  
more than a certain time or you will drain the battery.  they also  
mention to run the engine for at least as long as you ran the heater.
