This is a very good tool to use.
My input values come up pretty close to how long it takes mine to reach the desired temperature.

I have two suggestions:
1) Make a legend so people know to only put data into the yellow fields. (Even though it is protected)
2) Make it possible to change insulation thickness.

I think it should be a sticky for sure though. Thanks for putting the effort out to come up with this spreadsheet. Wish it was here a couple of days ago when I was started a thread on warm up temps.
