Facing an incoming Northern Winter (Sandpoint Idaho) and the 20's have already arrived this fall. Went out and bought this at a local Home Depot as I was curious to its performance. Brought it home, plugged it in, turned the ceiling fan on low, and successfully heated the dining room, Living room, and kitchen area of the Apartment in no time. Will be buying another for the main bedroom. This will save costs on using Central Heating, and two, Maybe three oil heaters should be enough to warm our apartment of a 1,000 Sqf comfortably.
