Herpstat or rheostat?

[tttaylorrr]

Touché on environmental factors. You also need to take those into account and based on the quoted post, you probably want a thermostat.

yup! i used a CHE + rheostat for well over a year when i still used glass enclosures. it worked perfectly for me because the room never fluctuated more than 3°. OP's previous thread made me believe a thermostat would be safer.

@OP: you know your environment better than anyone on the forum, and if you believe a rheostat will work then go for it! i just want you to be informed on their use and how they work.
