This is exactly what we needed.  We primarily heat by wood stove, but early in the season or late in the season , the weather isnt as cold and the wood stove is too much heat.  This heater makes it easy for us to hold off on our wood supply by taking the chill off the house quickly .It also allows us to stay away from home for extended lengths of time when the weather is very cold without worrying if our pipes will freeze or our animals will be cold.  Just what i was hoping for :)
