What cheap thermostat do you recommend?

Ummm im confused. Am i reading this right? Put the probe directlly in the heat tape? Heat tape warms up to 115 degrees plus when it cycles on so it would never keep tubs at temps and constantly cutting on and off

I had that question myself. I thought the probe went in the tub, but was secured to the outside of the tub. I have holes in my tubs right at the bottom where I put the probe through to rest right inside the tub, and then secure it to the outside of the tub with tape.
