The heater looks very nice cased in a nice wooden cabinet. I have it in the kitchen and it heats ok. There is no way this heater would heat 1000 sq. feet. I've had it on for a 2 hour period and only the kitchen gets warm. There is no wall to the great room attached to the kitchen and it does not get warm in there. I would say that this heater is only good to heat a single room or normal size.
