duane, i dont know anything about the yukon furnace. but the woodchuck is good, so is the brunco, i have friends that have these. and alot of others are good that i am not aware of. i have a jennings. put the big direct drive blower, and a 3-speed switch in case it was too much blowing air. i leave it on high all the time. it has a stainless coil for domestic hot water, but i never got around to installing that option. the fuel bill is almost nothing now. the wood furnace is used pretty much no-stop all winter long except on those unseasonally warm spells. what ever brand you get, i am sure you will be very happy withit. /forums/images/graemlins/grin.gif
