Beer carboy heater what temperature does it operate at
by Rotten Rodon January 11, 2019
It is best to use a carboy heater with a thermostat controller. That way you set the temp, and the unit will heat unit that exact temp you desire, then cut power and stop the heating process. Once the temp falls too low, the power kicks back on and it begins to send heat to the carboy to get it back to your set temp.
