Here's a post with more information on the iStill 100. What it is? Basically an iStill 50 column and management system, with a bigger boiler added underneath. For longer, more efficient runs of 8 to 9 hours instead of 4 to 5 hours.
The iStill 100 boiler has a gross capacity of 120 liters and can easily hold 100 liters of net boiler charge. The boiler weights 18 kilo's and is 85 centimeters high.
If you want an upgraded, 100 liter boiler to go with your iStill 50 system, this will add EUR 1.500,- to the bill. That's with shipping included!
