5 hours isn't too bad for the first "big" burn. After a month of reading here, refurbishing my old Ashley and getting comfortable with it out in the barn, Moved it into the house yesterday. What a diference from the old logwood stove I've been using the past two years. I didn't even know what a CAT stove was a month ago, but I'm sure glad you guys educated me. Kept the house a cozy 80 degrees all night. Set my air handler at 80 to distribute the heat to the further areas of the house and every room stayed warm. Nice to hear that fan kick on knowing the electric heat strips were shut off. Looking forward to next months electric bill. I can finally turn off those nasty heat strips for good. Thanks for all the info and help I've found here.
