Unless you want to switch the heater on specifically shortly before you

*keep* the seat heated.
True, but that's a little harder to work out without more experiments.
If you have enough heat to warm it from dead cold to butt-compatible in
a short interval, you're almost guaranteed to have enough heat to keep
it warm. As a nod to energy-saving, it might be useful to idle the
heaters at, say, 25% of full power, and switch to full power once motion
is detected in the bathroom.
It would be really neat if you had enough power to get the seat up to
temperature in the interval between dropping your pants and flesh
touching the seat. But you'd probably need a dedicated (PID?)
controller and lots of limit thermostats to make that even begin to
approach safe.
