We had this stove installed on January 8th. Just tallied my usage to date. We have used 9.5 bags from Jan. 8th-Jan. 21st during that time. Not to shabby at all....and approx. a third of those days/nights were below 20. Last night was 0 outside...brrr. lol Have not run the furnace one bit except for hot water. I have ordered that middle finger paper cut out to paste on the oil tank filler pipe when I do need to order oil for hot water. lol lol kiddin. Feels very good though to heat my home for a very reasonable amount of dollars.
We like it a lil warm but mostly in the living areas....we tend to like it a lil cool(not cold) in the sleeping areas....We have had some mild(what I consider mild...25-30 days/nights etc....) I notice the stove cranking more when it dips below 20. We have had some near zero days and nights so I crank the crap out of it lol....then back it off for bedtime.
