nice write up,

Quick question, if I'm using a CHE and a UTh to power the hot side to 92 on a thermostat. You wrote to put the probe directly on the UTH, if both are on a thermostat how will the probe take into effect the CHE since its under the tank? As of right now I put it on top of the substrate ontop of the UTh and under the CHE. wil this suffice? cause ppl say that substrate and stuff kills off some of the heat as it reaches the top layer.

Any truth to this?
