We've been running a 35-40 year old Kuuma wood furnace, but the time has definitely come for an upgrade. We've researched and seen a lot of different models of wood furnace, but we looked first-hand today at the Kuuma Model 100 and Model 200 wood furnaces at Lamppa Mfg. in Tower, Minn, where our original old Kuuma was manufactured. It's just down the road from our home in Ely (well, ok, about 25 miles down the road.)
Phenomenal performance, from what we can tell. They are also pricy ($3,800 for the 200 and $4,350 for the 100), but because they blow the 75% EPA efficiency requirement out of the water (they are up to 98 percent efficient, and flat-out stunned the lab folks who measure efficiency ratings), they qualify for the $1,500 federal tax credit, and since my wife and I both work from home offices, we also can write off about 20 percent of the cost of the furnace itself.
Has anyone used either of these models? If so, what are your assessments? Thanks!
