The 2.0 (and presumably 2.5) Roadsters have a 3.5-4kW heater. I bet that the S will have higher power still, because it's got a much larger cabin volume to heat.
What if you are in Arizona in the summer but want the car hotter then outside temp? Then the battery would overheat if it was setup like that. :tongue:
