![]() ![]() I am in agreement with previous posters the OPs chimney pipe arrangement is suboptimal. My local finding is the higher the difference between indoor and outdoor temps, the higher degree loss per hour I see. At -35dF the bottom falls out, I have crossed the exponential knee, and my degrees lost per hour increases rapidly with small changes to colder outdoor temperatures. ![]() I find my house "degree loss per hour" is more or less zero around +40dF, and more or less linear down to about -20dF where I am losing about 2 degrees (F) per hour. I change my burn schedule through all the variations down to overnight lows around -50dF with daytime highs around -42dF when my stove is swallowing three full loads daily. I typically light up in late August when overnight lows are dropping into the low 40s burning a small load on high to take the chill off the house before bed. I go through this every year, my answer is it depends on the weather. I’ll certainly be thinking about some of your thoughts to try to come to some conclusions… So, in that regard, it seems like running it a bit hotter may pay off, for reasons I can’t yet quite explain. So… I’ve been letting this thing run much hotter for the last 24 hours, or so, and it is still inconclusive… It doesn’t feel like I’ve been using any more wood, but my house seems definitely more consistently warm. Conversely, I just open it up a bit, and it burns way faster than I would like it to… Most of the time, After I get the fire burning satisfactorily, I run the thing mostly off… but it’s a very low burn, sometimes smoldering… And I can’t easily get my house temperature into a satisfactory range. If I don’t turn the damper all the way off, the thing will burn like crazy… But if I just put in the tiniest bit of air by moving the damper to the left, it starts burning hotter than I would like it to. The stove seems to run with two levels of damper… Either off or on. Most of the time, I have to leave the door open when I first load the thing, particularly after long burns, just to get the thing going. I have a PE Summit (which one would think would blast you out of a small house, which mine is), but it’s very inefficiently set up… It has multiple twists in the roughly 6 foot pipe that leads horizontally out to a T that runs outside of my house and up about 15 feet. Here’s where this question came from: I have a very inefficient system in my house. ![]()
