We live in a lower level and the temp is often 57-60 degrees when we get up in the morning. We turn on the heater in our kitchen and within minutes can feel the chill coming out of the room. It's very quiet and we find that it works just fine on the most cost-effective setting. My only complaint is the cord - it is too stiff, and doesn't lie flat on the floo, a possible tripping hazard. I'm just hoping it softens over time.
