We are currently going thru the financing part right now, for a new modular/sectional home this spring. But I want to get some thoughts from you guys, on a good back-up heating to pellets. We need a back-up thru winter because we do take weekend trips thru winter & I would not feel comfortable leaving pellets bur, while gone. Plus a 40 lb hopper won't burn more than 20 hours. I could get a hopper extension, to make it a total of 100 lb., but still wouldn't feel right leaving over night. What would be the best to get, not using propane ( bad situation), to use for what I call back-up heat because to me, when I am home, pellets are my primary heat. After getting financing, we will order, & I want to be prepared for ordering the system that works, when ordering home. Any help, would be nice. Thanks, Jeff
