Calculation of a Potstill + Thumper Distillation Run

Calculator originally created by Haggy, who taught himself a programming language so he could extensively test and contribute these calculators to HomeDistiller.

An assumption made is that both the pot and thumper have about 13% heat losses. This is fairly common to all stills.

If you do not know your pot power input, adjust the heat-up watts until the “Time to Heat up Pot contents” is close to your observed data. Pot power watts can also be estimated by matching calculated thumper distillate mL/min or final pot volume.

Time-step minutes are calculated by the program when set to 0. You can input time-step minutes in the range of 3 to 25 minutes. If you see that a longer run time is needed, use the end conditions of the first run as the input to a new run case.

Passive internal reflux in both vessels is included in the calculations. The calculations are based on comparing the thumper vapor %ABV and amount made results with real run data as described in the thread “Hail the Mighty Thumper”.
