Less money that a ssbrewtech top of the range and it has more toys on it. THe water jacket is also awesome as its less bits in the drink, less cleaning and less change of infection.
I like the idea of above as i can fire the boiling wort straight into it then use my chiller to bring down to the rite temp. It has a water jacket!!!! Im really conscious and dont like the water wastage the counterflow chiller does down the drain. If it dosnt work id have to build a closed loop glycol chiller circuit.
I was going to build my own but, some body already tried the idea i was going for and suggested its not that great and will need a serious amount of work.
