I was just saying that that's what heating cable proponents claim. I think 
the biggest advantages to the cables is an efficient way to heat the tank, 
although a regular submersible heater is a whole lot easier.

George did warn:
"Heating coil infidels like Scott and Tom scoff."

They must put some interesting stuff in the water supplies out in Colorado! ;-)

A real lab-style comparison would be nice here, but I don't think anyone 
has ever done it. Multi-year experiments probably aren't something too many 
hobbyists want to try.
