I'm going through too much wood already in this shoulder season. My Tarm has a big firebox and with 500 gallons of storage, the heat doesn't last too long. Last night with the temp around 40*, I started a small fire in my Lopi endeavor. Just a small fire. Normally I would have fired up the wood boiler. The wood stove kept us toasty warm in the living room, the wood boiler, from the previous morning start, kept the far bedroom heating zones @68*. Hot water was still available in the morning. What I'm saying is I think I can sometimes save on firewood by burning the woodboiler less frequently, by starting a small fire in the wood stove. Anyone else burn both?
