In winter, running a small block heater for 1-2 hours before leaving is cost effective.

I was more looking at engine temps. Operating temp for my car is 192F, Low Fan Speed at 223F and High Fan Speed at 230F, people say that the coolant will boil at 260F. How hot should I let my engine get before taking action? And how does engine temp impact MPG?
I'm going to install an OEM Block heater before this winter so I'm all good on that front!
I currently have a Upper and Lower side grill block in place and the hottest my engine has been is 208F.
