Anyone has some experience and can recommend or don't a system like Ace Micro Brewery/Klarstein Mundshenk etc? I am planning to either buy one of those all in one or make my electric pot (27L) for traditional mashing with a stirer and a spring filtrator at the bottom. So during mashing I will stir and use a PID controller to keep a temperature and after mashing I will filter it down to basket, clean the pot and boil in it again. I heard efficiency with this all in one system is quite poor? Is that so? I know a guy with a similar system as my second option with the electric pot and stirrer and he is getting 80%+ and is able to mash 9.5kg easily while all those all in one have 8kg limit right? Also do you know what kind of temp sensor is in the Klarstein Mundshenk? Is it ntc thermistor or pt100 maybe?
