I hope that the A/C in Model 3 is the reverse-cycle type so that heating is far more energy efficient. I have a Gen 1 Leaf with resistive heating and I can tell you it sucks (the battery) big time, whereas even intense cooling barely moves the needle.
Gen 2 Leafs onwards have reverse-cycle A/C. Tesla would not want to bring a new car to market in 2017 and be outdone on something so basic.
A resistive heater could be part of the Cold Weather package, should people need it for that reason.
