cheers mass, I think I have gone a little overboard with the insulation, but I love the look of it.
I hear mixed opinions about scorching the wort but if you ask me I see many people using the keg king straight elements which are not low density, and non, of them complain about scorching. As long as you keep circulating then you should be fine. Personally I think that you will need two elements when ramping and boiling and you will only need one for holding temperature.
Fellas my +1 is that there is a formular for this sort of thing. Density of the liquid to the surface area of the element.
The Co that supplied my element worked it out from the density of molases.
The companies called Cynebar, they where very helpful.
