RIMS uses either heat from a burner to heat the mash tun or uses an electric
heating element in the flow line of the recirculating wort when temperatures
need to be adjusted up.
HERMS is not different except that instead of an electric heating element in
the recirculation line, the wort is pumped through a copper coil in the
liquor tank. HERMS is reported to not scortch the wort as is possible with
the RIMS setups.
I'm putting together a HERMS system mostly because I want a RIMS system
without all the hassle of an electric heat element and I prefer the Gott
cooler as a mash tun (using a burner on a Gott is not recommended).
PBS will claim trademark on the HERMS acronym (sp?). So be carefull how you

RIMS uses a heating element in a loop of recirculating mash liquid. The
element is in direct contact with the heater surface, hence the chance of
scorching the mash if the heater element is too high of a watt-denesity. I
find it hard to get a heater big enough to heat 60 quarts of mash.
HERMS has the heater contacting a heat transfer medium which through which
the wort runs in a coil (which could be considered a closed loop). No
direct contact between the heater and the wort. The set-up is otherwise
pretty much the same idea (pumps, false bottoms, heater controllers,
Help at all?
Thank you again.
