No, With the amount of time, effort, and modification it would take to convert a house thermostat into one suitable for heat pads, you would be better off just getting one already made for it. I'm not a master electrician but the house thermostat you linked looks like it runs on 240v...
I'm going to say NO! Besides, how would you use a probe with that. If you are on a tight budget, you may want to look into Johnson's Controls or Ranco ETC-111000. If thats still to much then look at this. http://www.bigappleherp.com/BAH-1000-Thermostat
You really do not want to skimp on the thermostat, your snakes lives depend on it.
