I received the Velocity 3 Whole Room Heater just in the nick of time our weather is in the 1 digits so my home office which is a 12x14 room and stays cold. The heater is small but powerful and warmed our room to where i did not have to wear a jacket. It warms  up the room fast when it reaches the temp it is to be it shuts off and back on when it gets under that temp. It is very nice addition to have when weather is
 very cold outside.
