Due to our long steep driveway, we can't count on getting oil delivered in the winter. We have our two 275 gal tanks filled in August and then use a combination of burning oil and pellets plus running two heat pumps. After installing the heat pumps our pellet use dropped from 4 ton to about 1.5 ton a year. The pellet stove now just heats the LR, about 40% of the 1st floor. Prior to heat pumps it heated all of the 1st floor plus helping with the 2nd floor.
