I assume you are currently using extracts exclusively? If so, and you have no plans to beginning all grain brewing, the false bottom wouldn’t buy you much of anything. The thermometer and ball valve are simply convenience items. Instead of worrying with a thermometer dropping in the pot or on the ground and needing cleaned and sanitized during chilling, it’s simply always there. No muss no fuss. Same thing for the ball valve, in that you don’t need the siphon to transfer to the fermenter. Of course I’ll warn you up front that a ball valve also means a pump for whirlpooling is not far off. Of course since you now have a pump, you might as well get a false bottom and a bag for BIAB all grain batches........... list continues until your family either think you’ve lost your mind or you should open a brewery out of your garage. All because you got tired of sanitizing an auto siphon and a thermometer. Ok, may that’s just me, but now you can’t say you haven’t been warned.
