We’ve been using pellets for 15+ years. We live in central NH. Our home is a 1760 sq ft two story cape with propane forced air heating and cooling. Last year we replaced our old “Enviro” with a “St. Croix.” Although St Croix is not a top shelf stove we love it. We use it as our primary heat source. With a little help from a fan we keep both floors comfortable through even the coldest of most winter days. We burn “Vermont” pellets. They are a premium soft wood pellet that runs about $40-$60 more a ton. We got three tons last April and paid $300 per with a $100 delivery. We average about a bag (40 lbs) a day. One thing to keep in mind is that pellet stoves are not wood stoves. Soft wood pellets for the most part burn much more efficiently and at a higher temp. They produce less fly ash which means less cleaning. The new stoves are much more environmentally friendly. The pellets we burn come from a farmed and sustainable source and are carbon neutral.
