So I've had my ZHP for 2 months now. I've noticed that it takes much longer to warm up to full operating temp than my 325 as well as my dad's normal 330.

For example, I have a ~15 mile freeway commute from class (at night). By the time I get home the temperature is just barely on the little icon in the middle of the temperature gauge, but I can tell it's not fully centered, and therefore, not fully warmed up.

Any thoughts on this?
