Query: Very Disappointed

After having read the majority of the reviews for this heater I really had fairly high expectations for it. I wanted to replace the Lasco 75800 Cyclonic heater we use to heat the bedroom because of the length of time it took for the heater to warm the room. The room is about 11' X 15'with an 8 foot ceiling. Unfortunately the heater doesn't work as well as the Lasco which I will continue to use. We'll use this heater in a smaller room. I was very surprised that it didn't work better since it puts out warm air on both sides and through the top of the heater. In any event I don't recommend it.
