You warm your stove to 200 degrees and shut it off. Put your pan of dough in there to rise with a damp cloth.
You still have to check it to make sure its not getting to hot or to cold.
On mine I set my bread on top of the stove and open the oven door a bit. I also heat the cloth in the microwave.
(I live in Idaho and keep my thermostat set to 65 I kinda know about the cool house thing)
Hope this helps
