Greetings firewood friends! I’m back at it, actually I never stopped wood hoarding, but I’m back at wanting to install more fisher stoves. Currently, my ~3000sq ft well insulated 2 story house with basement has a primary forced air oil furnace that I supplement (only to conserve fuel and save money) with a 1st floor Buck non-cat model 74. My garage has a baby bear installed and I love it! The Buck 74 does really well as a supplementary source, but as usual, a 1st floor stove makes for a very uneven heat. What I’m thinking of doing, and the wife is not opposed (she buys the oil - and loves to split and burn wood), is disconnecting the oil furnace exhaust vent pipe from the central (newly lined) chimney and installing a basement stove. I would shut off the oil supply line, but leave the existing forced air furnace in place and online so I could use the fan to circulate the air. Ideally, I would like to install a Fisher momma or papa bear using double/triple wall (for clearance safety reasons) to the central lines chimney stack. I would continue to run the buck 74 as supplemental and for the ambiance of course. We aren’t planning any extended periods away from home so keeping the house up to temp would be no issue. Even if we did plan to leave, all I’d need to do is swap the stove and oil furnace chimney/exhaust connection pipes. 10-20 min task at best. Has anyone ever ran like this? I found a reallly nice looking Papa Bear somewhat local on Craigslist but the guy is at $400 firm. A bit steep if I recall? Then a few sections of Selkirk insulated chimney pile from Menards and we would be in business. What do you all think? Our house holds heat very well and we spend somewhere in the realm of $1500 per year on oil. Firewood is ENDLESS days and my 3 year supply , thanks to all of you, is in place. We would really like the warm floors in the morning!
hmm...sounds like it would work as long as you have the right chimney...I am sure Welder Dave and Coaly will be along with top notch advice soon
Had the masonry clay chimney lined which I plan to hook to relined 2 years ago with a 6” stainless liner in which the oil furnace is currently connected to. I was sure to install a liner that was rated for oil, wood, and coal. I’m rather confident that the standing chimney is sufficient. The remaining connection from the back of the stove to the thimble will be interesting though. It will need to run approx. 6-ft. Additionally, it needs to split the gap between the stairway and the primary cold air return duct on my furnace. At one time, many moons ago, there was an old wood burner in the same spot but they had asbestos board shielding on the stairs to protect from heat so I know it’s possible. Using single wall pipe seems unsafe though so I would plan on full triple wall (actually double wall as I understand). If I use Selkirk from Menards, the cost shouldn’t be too awfully bad. Feel as though that long of a “Horizontal” run would need a stand or jack of sort to support it. Still thinking. Meanwhile, another Massive cherry uprooted in the woods. Firewood is endless round here.
You don’t want 6’ of horizontal pipe. You also don’t need to use class A chimney, you need connector pipe, not chimney. Double wall stove pipe only requires 6” clearance to combustibles.
