That's right, I use the RUN position because the AFR gauge doesn't work unless it's in the RUN position.

I just did a test. I set the key to the ACC position and I waited for a bit. Then I set it to the RUN position. If the heating element had been on, the gauge would have shown "L" for lean when I changed to the RUN position. This did not happen, so the heating element (at least on my car) will only heat up in the RUN position.
