Hello!
Sorry for late reply.
Again, thanks for your feedback.
Your concerns are clear and well described. If you are a satisfied user of eHERMs system, it will be difficult for us to convince you otherwise, especially when our price is higher.
I will only comment on two points.
1. Efficiency - there are of course many ways to calculate the percentage. When looking to Kunze, you`ll be surprised finding that the mos efficient industrial brewhouses are far below 90%...). We do not give percentage. We say, what we can do same wort with less malt. We occasionally figured that out, while brewing the recipe of one of the recirc system user.
2. Time for mashing: It is of course depends on the mashing profile. If you have only one pause at 62C or 65C, than you can probably do it quick. You can also do it with our system. On top of this our system offers an opportunity to have multiple steps (52C, 62C, 75C, 78C, for example).
