Since there are a lot of questions concerning "Will a pellet stove heat my house", I thought I would throw together a quick diagram showing the heat distribution in my house. I figured if a few people could post their heat distribution, it may help others determine their pellet stove needs. Obviously this is dependent on several factors (stove, pellets burned, age/insulation of house, etc.) My house is a tri-level home built in '78. The house's insulation is adequate but not great. We installed newer windows on the main level, and in the master, but still have older windows in the back bedrooms and lower levels. Additionally, our front door is really drafty and causes some heat loss with the heat traveling from the lower level up through the main and upper levels. The below diagrams are with my stove set at stove temp medium/low - however I can raise all of those temps by 2-4 degrees if I crank the stove. Additionally, the lower level thermostat is out of the airflow of the stove blower, so the actual temperature in the center of the room is very warm. If the temps get down to zero or below, I have to crank the stove at medium/high to maintain those temps. The stove heat about 1800 sq ft (for my setup) we have a 4th level of about 400 sq ft(a finished attic) that is not well insulated, and we keep the door closed and use boiler heat up there when we use that space. Hope this was helpful and for anyone that wants to create their own: http://www.smallblueprinter.com/floorplan/floorplan.html It would be great if others with differing style homes, could post some simple diagrams outlining their heat distribution for others looking for advice.
