The whole point of using the cables is so you do NOT get an even heat across
the entire substrate. Dupla (supposedly) established a given distance
between the parallel cables so that it would result in a convection current
that includes the entire substrate. Heat the whole thing, and the currents
do not develop. Instead, the heat rizes out of the gravel into the water
column without taking the warm water with it.
