One of the problems with the "Cantenna" is that the oil stays in place
and forms strata when you put in the power.
No need for any "Fancy" heat Exchanger....
To give me some more "leeway" I install a small dc powered lab pump using
some fishtank air fittings and then  some plastic tubing  I connected the
"Cantenna"  with a second 1 gallon can of oil next to it I have tested
this setup up to 3KW for up to 5 min cont, Yes the Oil gets hot but it
take it...
