hey guys nice to be here. My wife works for lowes and we are looking into maybe buying one of the summers heat pellet stoves to supplement our central heat and air unit in the winter. Is this unit worth looking at? If I do buy it do pellet stoves have to have a chimney that run all the way up above the roofline or can you just vent them out the wall. btw I can get a good deal on the stove, it is the one that is supposed to heat 1500 sq ft I think. Thanks guys.
