The RIMS section of my brewery has changed very little in the first year of use. It has performed well and produced over 20 batches of excellent beer.
The details on each part of the RIMS system may be accessed using the links at the top of the page.
I'm planning to change the current direct wort heater to a heat exchanger in the near future. The direct heater works great but must be disassembled and cleaned after every batch.
