I searched for this in other threads but wasn't able to find a thread on this. I have a general question about the mashing technique for RIMS. Please forgive me if some of the questions seem idiotic
The reason I am asking this is because used my new "semi-automated" rims (I manually switched the heater element) system this weekend and my efficiency came in really really low - around 55% based on my Beersmith calculations. With my usual cooler and infusion technique I regularly come in at 75% or so. I don't understand this because my temperature only once exceeded 155 degrees F or below 148 degrees F.
1) I assume that you generally leave the pump running all the time. I am using a false bottom and it seems to have worked very well. Do you in fact leave the pump running all the time?
2) In order to complete a mash-out I batch drained my mashtun and added 170 degree water, which I then recirculated while starting to boil the wort.
Am I way off here?
