Fine tuning set up

[IMALOSERSCUMBAG]

I have a 26 gallon boiler, (4) 4" dia. sections into dephlegmator reduced to a 2 1/2" shotgun condenser out a parrot. I use a 5,000 w element to heat.

I have been trying different things to get better efficiency and think I may be making some errors. Any input would be appreciated. I'll explain my typical run.

Fill the boiler 20 or so gallons and turn on heat full until I get to about 90d C and crank down until the temp stabilizes just under 100d C. I try to stay under 100 because that's where water boils. The water to the dephlegmator and shotgun is on. I think my first issue is my water is actually to cold. I try to maintain it at (50-55F) 10-12d C.

I will dial the water to the dephlegmator until the internal vapor temp hits 80d C. And maintain 80d C as much as possible. Depending on what I'm running I get a fast drip or steady stream (pencil lead).

This process tends to take anywhere from 10-14 hours. From my reading that seems too long. Thoughts to what I'm doing wrong:

Should the water in the dephlegmator and shotgun be higher?
Should I allow the vapor coming out of the dephlegmator to go higher?
