As the weather got cooler, running the basement Summit stove has been interesting. In a good way. When we built, we insulated the house very well, including the basement.
So far, our coldest night this heating season was -18C. Overall, it has been above seasonal. My lake is still open water in the middle, it is a deep lake (325ft) but usually it has froze by now.
As for the convection flow... there is a significant latency, where I can heat up the basement with the woodstove running all night, go to work in the AM and let the stove run down to coals while I am away. The heat from the basement continues to rise into the upstairs via the stairwell, and by the time I get home from work, the upstairs is still at 21C and the basement has cooled down to 17C. So the furnace never even kicked in, as the thermostat is on the main floor.
I stir the coals, load the stove, and repeat the cycle. I had budgeted for 3 days per week burning wood, but it has been 7/7 instead. The oil truck showed up this week, I intercepted him in the driveway and informed him our tank is still full, skip the refill. His previous customer was 575 liters of oil, and the total bill (taxes inc) was $1380 CAD. Ouch.
Sorry not sorry Oil company, but my stove and chimney are going to payback much sooner than I had planned.
