Since getting my HERMS going with Nevs coil, I have noticed that the reading for my wort return and the reading of my grain bed differ by about 4 degrees.
So when the returning wort is at 69, the grain bed is only at 65. (Both thermometers are calibrated and digital).
Should I amp the HERMS up by 4 degrees to get the grainbed to 69 and have the wort return running at 73 or should I rely on the temperature of the wort return.
What do you guys do?
