Input: Consider Input: This is a fantastic seemingly small heater. But it is a mighty one!!!This heater comfortably warms my main basement room which is approx. 25 feet x 25 feet. I leave it on the medium setting and the thermostat works excellent: the heater does not stay on constantly. The heat temp rises to a nice warm, toasty level; shuts off and when it gets a little chilled, goes right back on. The best heater I have bought! I went thru 4 heaters last winter till I finally found this one that is still functioning!!!


Output: Positive
