I wanted to thank everyone for the incredible responses and discussion, I would like to discuss the topic a little further and gather additional thoughts from you.
For those of you who are running the 14 ga wire how are your routing the wire?
I have not actually measured the total length of the wire run but I estimate if you ran the wire down the spar tube and back to the pitot probe you would have at least 18 ft and that doesnt count running the wire through the cabin to the power source. P. 75 of the G3x install manual calls for 10 g wire for distances of 20 to 30 ft.
I purchased the unregulated pitot so unfortunately I do not have anything which would decrease the demand of the heater. Perhaps Stein would work with me on this and I could trade up.
