i have a register in which i had a small computer fan last year and the heat was coming up from the basement (with pellet stove) at 80 plus degrees to the upper level of my bilevel. this year i am going to try an extra fan i have left from my gas fireplace that i sold. it had a snapdisc for turning on at a pre determined temp. i was wondering if there is either a snapdisc or another type of thermostat i can use inline to turn the blower in the floor on at a pre determined temp or variable would work.....then all i have to do is adjust the speed. thanks......
