4 F at 1:45PM here in NE PA. The winds are blowing. Tonight, I think at least -5. The house is a toasty 70F with the Oslo just idling along at 350F. It's real easy for this stove to keep this house at any temperature you want.
Update -18 at 8am. The wind was howling all day yesterday. Much calmer now, but still moving the trees around. The stove alone keep the house perfect last night. The cold doesn't bother the birds on my feeders, dozens of them out there now.
