So I took on this huge stair job, super ornamental, and out of town, so I figured to make it easier on the lady of the house, I would buy some sawdust logs. They heat swell, and are easy to handle and get lit etc. but they sure do burn fast. Some days she has burned 3 bags ($6.60 per) by the time I get home. I am thinking it would have been cheaper(much) to get an oil delivery. Any thoughts? I originated this thread in the ash can because I didn't want to denigrate somebodys product on a public forum.
