Soon to be owner - tank setup / heating setup questions

[snakesRkewl]

Based on everyones feedback, I'm planning to put the thermostat probes on the UTH and bury the thermometer probes under the substrate against the glass and just check that they haven't been displaced every once a while.

Good choice, thermostat probes should NEVER go inside the tank it's just too risky no matter how you hold it down.

With on/off thermostats I set the low point around 92 and when the t-stat kicks on it will go up to 95-97 for a few moments then drop back down to 92 before it kicks on and repeats the process.
I have never had a burn or any issue with these temperatures, just happy well eating snakes that love their hot spots.
