I'm gonna rework my heating system pretty soon - read this summer. I was pretty sold on another wood furnace down in the basement, but I'm trying to weigh all my options. Here's your shot at influencing my decisions, giving me ideas I haven't thought of yet, or just voting on a poll for the fun and giggles of it.
Here's the background. My house is a 16x70 trailer, sitting on a full basement with 7' floor to ceiling clearance, mostly unfinished. Water, gas, and furnace plumbing hang below the floor. I have an old Woodchuck wood furnace down there for my main heat, with a gas wall heater for emergency/vacation use, not normally in service. Upstairs is the factory LP forced air (have yet to light the pilot this year, but been close the last week of colder weather). Currently, I burn 8 cords a year on average. I have the house to myself and the dog and cat, but that's subject to change. The biggest problem with the current setup is even heat distribution. It's commonly close to 90 downstairs, and in the mid 60s in the furthest corners upstairs. I have 3 different fans running to minimize this right now.
Here's where it gets fun, fellow woodburners. I've got 3 options I've been thinking of:
Option 1: New wood furnace downstairs, possibly a combo wood/lp backup. I'd be installing a new chimney (SS, inside the house) for this, as well as having some low hanging ductwork near the stove to meet needed clearances. I THINK I could tie into the factory ductwork for upstairs, and run ducts to the ends of the basement for better heat distribution. Cost: $7000 give or take a grand probably.
Option 2: OWB, gasifier type. I've got lots of room for it, no restrictions here yet, and it'd keep wood mess outside along with not needing to get wood downstairs. Biggest drawback is cost, I'd be looking at a HX for the upstairs furnace, and a baseboard system downstairs. Probably north of $10K by the time it's all said and done.
Option 3: Big wood stove down in the basement for main heat (as above, new chimney. Had it beyond up to here with my current outside block and clay chimney), and a smaller wood stove upstairs. I'm guessing that the small stove would be real handy on those days when it's just a little chilly in spring and fall, but lighting the big stove takes too long to heat the upstairs, so you wind up cold or tempted to touch the dreaded slider in the hallway and hear that evil whoof sound. It'd also run when it's subzero outside and the bigger stove can't keep the whole place toasty. Downsides of this are 2 stoves and chimneys to maintain, and I'd probably wind up remodeling the downstairs to have the stove in the main area. Upside is it's probably the lowest cost option, especially with being able to do it in stages, instead of writing one big check.
Option 4: Your call. Let me know what you'd do differently than what I've already come up with.
