This is my first year be a house owner. This is my first year need to take care of the winter heating. This is also my first year using a pellet stove. Started from thanksgiving, we have used 3 tons of pellet for my 1600 sqft ranch. Our Quadra 1200i did a good job but the result was not as we expected regarding the room tempertures( living room where the stove installed was about 70F, bedroom about 60F). The result might be caused by the following reasons: 1. house insulation is not good enough. we have two big (8'x4') windows and two normal double hang windows in our living room and they are old. The wall insulation is not good, I think. Our cast iron radiators were inserted into the wall, so there is only one drywall there. 2. don't know how to use the stove efficiently. many times we used lower setting (lower blower speed) with higher feeding opening. We should use higher blower speed and lower feeding opening to get more heat out of the stove and minimize the pellet comsumption. 3. air circulating was not good. we should have some sort of fans to force air circulating around those rooms. 4. stove blower stop freqently sometimes (as I reported on this thread: https://www.hearth.com/econtent/index.php/forums/viewthread/11761/), during that period, there was no heat flowes out from the stove. When we start the stove from room temperature, it almost always takes about 20mintues or more before the blower start. Even today, the blower still stop, go, stop and go (far below the expected temperture and the stove still in heat calling state). I am not sure it is caused by a bad snap disc or it is caused by the stove is not hot enough. Anyway, the spring is here and we are planning to do something in order to improve our situation next winter. We like summer because we have a solar panel hot water system and our house is good for summer. Last summer we did not turn on the central air system.
