I have a couple of questions I hope you folks can help me with. I have a cape with a downstairs floorplan of 1000 sf, the house has a center chimney with two flues. One flu is used for the oil burner and the other for a Jotul F3 that I installed in the first floor fireplace. The oil burner is in the basement. My wife and I plan to turn our cape into a Colonial this fall by tearing the exiting roof and walls off the house and putting 8 foot walls and a full roof system with attic above the second floor. The Jotul keeps the first floor at a decent temp if monitored closesly (filled every couple of hours). It gets chilly here in Maine and my thought are as we start a family and expand our home I'll need more heat and I'll have less time. I'm trying to determine how I can put a large woodstove in my basement that will have good burn times without having to invest in a chimney that goes up three floors and requires tearing apart my house. Anyone have any experience with direct vent oil burners? I want to keep the exisiting hot water system as its nice to have a reliable backup and be able to go on vacation, etc. Any ideas on how I can get a big motha wood stove in my basement with my current setup? If I can get my oil burner venting via another method I can use the flu for a new wood stove. Thanks everyone.
