Hey everybody. Been lurking around for about a year but this is my first post. After two seasons of heating with my LT90 I'm wondering if I'm using too much wood. I live in SE Michigan. We have a 2500 sf Cape Cod with 1900 sf on the 1st floor & 600sf on the 2nd floor. The house was built in 1990 with a propane boiler and hot water heater. I installed the OWB myself using heat exchangers for the indoor boiler and the water heater. We usually fire up the OWB in late Oct. and let the fire go out in late April. So far in the first two heating seasons we have used approx. 40 facecords of wood (4x8x18 deep) per season. The only good thing is that the first year I bartered 20 facecords and paid $65 dollars a facecord for the other 20 ( All Ash). The second season, (last winter) I found a neighbor who is a tree cutter who sold me 40 facecords @ $40 apiece delievered. Just trying to figure out if this seems like a lot of wood that I am burning?
