I was able to pick up a used wood burning stove for $100 at a garage sale; the venting for it came to around $250 because we are in a windy area and needed a flu top that would be safe. I’ve seen wood burning stoves in our hardware store ranging from about $200 for the smallest to over $500 for larger models, but that’s all I know about them.
Installing the venting is VERY EASY: Measure the distance from the top of your stove to exit point (wall or ceiling) and add an additional foot plus the height of your roof eve. Add footage and elbows for horizontal piping (if you plan to go through a side wall instead of straight up). We went this route to avoid making a hole in the roof. Seal the cracks w/ an appropriate compound (we used “Great Stuff” since the wall vent was insulated). If you go through the roof, make sure you use appropriate flashing and roofing sealer. You will also need an appropriate size flashing to make the inside and outside holes pretty and help keep the piping in place. Make sure the vent is for wood stoves (as apposed to gas or furnace exhaust) and the piece that goes through your wall or ceiling is designed for that (I think it’s called “double-wall” but check w/ whomever you purchase it from). We learned the hard way that you can’t use a gas vent top for a wood burning stove, so don’t try it if for some stupid reason the store you’re buying the venting from doesn’t have the right vent top. Make sure to pick up a collar (ring that joins vent to stove) for the stove to the vent and a few straps to attach the vent to the walls on the inside and outside.
Some other tips: Wood stove outlets and hardware store have venting sealers for leaks in the venting. These leaks are generally avoidable if your venting is installed flush. Minor leaks will tend to seal themselves with use if you can stand it.
It sounds like a lot, but my husband and I got our installed by ourselves in about half a day, once we got all the right parts. If you are purchasing yours new, I would recommend having the store deliver and set it if possible. THEY ARE VERY HEAVY. Otherwise, we pulled our stove on a piece of plywood into our cabin. You may want to use plyers or some other type of gripping tool to help (he does flooring, so we had carpet pullers to grip the plywood with and pull the little beast up two steps and into our cabin). I’m pretty small, and he’s larger than average, but it can be done.
Our stove heats our small cabin, and we also use it to cook and heat water for evening showers. It is about 2 1/2 feet tall and 2 feet wide with two flat surfaces on top, by HomeWorks, I think (I’ll double check that when I get home). Our cabin is approx. 400 square/feet and as of yet, uninsulated (I know, my bad!). It takes about 20 minutes to heat up the entire area, and it keeps us warm for several hours after we go to sleep (it gets in the 20’s here).
We absolutely love our wood burning stove and highly recommend one for off-grid living…especially when there’s dead wood laying around just waiting to be cleared. Best of luck to you!
Good to know about the neutral CO2 emissions! Thank you!
