I am pleased with the stove. It can produce enough heat for the entire house 2300 sq. ft
I also have a Whitfield, but I find the Harman produces much more heat using less pellets and much much less ash. The only drawback, I've been having trouble with noise when the auger stops feeding pellets. It only happens when I use a certain brand of pellets. The pellets are premium pellets and are from a Harman dealer.
