The heating furnace went out in our hunting camp and we needed a new heat source.  Since we will only be there a few months out of the year, we got the VMH600 Whole Room Stainless Steel Heater with Auto Climate.  This unit is amazing!  It heats out 40x40 area with no problems. It has the auto function that controls the temp in the room to keep it constant. Vornado made a smart move with manufacturing this product.
