Take the advice given and don't try to do too much all at once. You will end up messing up some part of it and my odds are on burning your pan. It's too easy to get distracted and poof you have a mess. I do a lot of small draws through the day and I put all my finished syrup together and that makes a nice blend. I have even used an insulated water cooler rated for hot liquids. My syrup is usually still around 100 degrees in it at the end of the day. I can then check density while the temperature is stable and it takes very little heat to bring it back to 186 (what I bottle at) and we have time to set everything up for just bottling. If it's too late we just wait another day, but being small I can usually do it that evening after shutdown. It really does not take long to do a few gallons when your all set up and just bottling. I draw at near syrup and finish on propane and filter off the finisher. That I can do as I boil or as I go through cool-down at the end of the day.
