Hello Since it has been cold (15 - 25 at night and 25 - 30 in daytime) I am burning about a bag every 24 hours, I usually add a full bag each night. Hopper holds 115 lbs. Also, What Wood Pellets are you currently using? The Logic-E wood pellets I use from Canada have low ash so I clean out the ash Wed and Sun to keep it going good. Don't forget to say what stove you have if it is not in your signature.
