I have a fawcett wf200 wood furnace from 1979. The automatic damper is long been broken and we adjust it manually now. We usually get about 4-5 hour burns out of it and go through about 5-6 cords a winter with some oil use. I wanted to get something that might save me from burning as much wood and give me longer burn times. I bought an Englander 28-3500 from Home Depot. I don't have many details about the old stove, it looks kind of like the one here but with no autodamper http://www.enterprise-fawcett.com/wf_series.php . Could someone tell me if the new Englander 28-3500 furnace I bought will be an improvement or just be the same as the old? Thank you for any opinions shared.
