The Jotul Oslo continues to be one of the most popular and most asked-about stoves on these forums. With that in mind, I thought I would give new and prospective owners a mid-January report of actual operation.
Today's high was 18 deg. f. It has been slowly dropping all day and is forcast to be on its way to 0 deg. overnight. The house temperature is a very comfortable 70 deg. back at the bedrooms, and 71 deg. upstairs. I have no idea what it is in the family room where the stove is - pretty warm, though! At 6:00 pm I loaded for the fourth time. I happened to notice that the stove top temp had dropped to 350 deg. f. before loading.
At roughly five hours between loads, I am not quite pushing it to the max, but it is getting close. At these temperatures I need to open the air control after about four hours (about mid-way) to keep the stove temps up and to prevent an excessive build up of coals.
The fastest way to get the stove up to maximum temperatures on a reload is to open the air up to 3/4 open or so, put in just three or four sticks for about 10 minutes, then finish the load. If I do that on a good solid bed of coals I can have secondaries in five to 10 more minutes. I then close it down to 1/4 open, or a bit less.
If it does drop to 0 deg. tonight I can (a) turn the furnace back on, (b) get up about 2:30 am and reload, or (c) just deal with a house that is 64 or 65 deg. come 6:30 am. The last is not a good option as it would take all day to get the house back up to 70 again if it stays that cold outside. Should it warm into the mid to upper 20's a single good load will warm the house back up.
People often ask about cleaning the glass. I clean mine regularly. Got it the last time in March, sometime. It's about due again.![[Hearth.com] Jotul Oslo F500 Mid-January Report [Hearth.com] Jotul Oslo F500 Mid-January Report](https://www.hearth.com/talk/data/attachments/172/172293-5a7d77b83491375e9ce1cf0e83c77e27.jpg?hash=54OJA2OY9k)
Stipulations: The stove is slightly undersized for the size of my house; I chose to be a bit undersized for the rare extreme cold events so that I could comfortably use it more often during the long shoulder seasons we have here. The well-insulated house is over 2500 sq. feet on two levels, plus another 1200 sq. ft. in the unfinished basement. I burn seasoned oak and hickory - cut, split, and stacked for three years. The stove is centrally placed in a semi-open floor plan. The 6" flue is straight up for 30'.
