Low resistance heating elements are bad because you end up with a lot of resistance in everything before the heating element. Studies have shown for direct connect that and element of twice what you think is ideal gives higher total daily output. Power point heater control is the way to go to maximize output. It takes twice to three times the panels to get the same performance. The science is out there, no need to just waste money experimenting with disproven ideas.
