This is a pot still so it would be good for flavoured/brown spirits. It wouldn't be much good for neutral/vodka. The t500 reflux still that sat on that boiler would be better for that. I couldn't tell you how long a run would take sorry, someone else will be able to help there but the spirit run would take a fair bit longer. There's no need for temp monitoring on a pot still, an alcometer will serve you better.
Just for your reference here is a link describing the different still types
