Household thermostat?

[Desert]

I'm sure others have had this thought and most likely someone has tried it out already. Has anyone had any success using a household thermostat to control your rack heating? Not the room temps, but the flexwatt temps.

The only purpose that would be served by using a household thermostat is the unnecessary complication of a rather simple application. Household thermostats are low voltage controllers that control relays. They are not full load controllers and cannot work alone to control your rack heating without a relay circuit in place.
