Assume you would want to counterflow at both heat exchangers. Your column condenser was plumbed backwards. Flow down and then out.

The counter flow at both condensers is definitely an upgrade you can do to make the recirculation better. The current way will work, though.
It’s not plumbed backwards. Pump water in from the bottom, daisy chain and out from the top into the bucket.

For maximum efficiency the cooling water always needs to flow opposite direction of the steam.

1 KW of boiler power will raise the temperature of cooling water flowing at rate of 1 Liter per minute by 14F. You can then easily calculate how large of a water reservoir you will need to complete your batch. Remember a plastic tank will insulate the water against losing any of that heat so a metal tank is a better option to reduce heat buildup in your cooling water. Don’t forget to add in the Wattage of your pump if is of the submersible style as that will also add heat to your cooling water over time.
So a 2 KW heating element will raise 1 liter of water temperature by 28F every minute. A batch taking 2 hours to complete would raise the temperature of 100 Liters of water by 33.6F or 50 Liters cooling water by 67.2F.
Since you are likely starting with 55F water right out of the tap you add that heat to it & come up with 88.6F for the 100 Liters or 122.2F for the 50 liter tank.
Yet another reason not to use a plastic tank.
Oh & don’t forget if it is exposed to outside temperatures of say a 90F day that will also add to the heat load.
So be sure to use too big of a water reservoir!
Hint.. a 55 gallon steel drum holds around 200 Liters of water but be warned it is darn heavy!

Awesome notes, man! Great input!
