Of course you'd need a heater, herefishy my friend. The cable heater is by nature low wattage. Its gentle heat rises, pulling the bulk water into the substrate like a conveyor belt. You can argue the necessity and effect of a sub-surface cable heater until the Cowfish come home, but they do one handy thing; they keep the substrate fresh - no festering dead spots.
Just FYI, the cable heaters are in all eight freshwater planted. And yes, I can tell the difference with and without, just like with and without pressurized Co2.
