An interesting contraption

sedorestovewest.com

A wood gasification stove.  Burns clean, burns all sorts of stuff and you can drop an enormous log in it.

I agree that it is not as good as a rocket mass heater, but it is fascinating!

First, sorry for bumping a 9 year old post.

These stoves look like a great option, I have been considering having one installed. Has anyone had any experience with them, I have found quite positive comments about them on other forums but I was hoping someone in the permie community would have some knowledge regarding them.

Hi I bought a Sedore 2000 model last year and I love it.  I am gone 12 hours a day and this stove stays lit for 14. To me that makes it worth the price. No more coming home to a cold house EVERY DAMN NIGHT and getting the fire going. With the Seodre all I have to do is refill the large burn chamber and im good for 14 more hours.

The Sedore is more of a furnace than a stove  throws far more heat than my previous unit that was rated for 3000 sqr ft.  
Like a RMH the Sedore is a down draft stove which has 3 big benefits. Because the fire is always at the bottom not at the top in a conventional heater you can load the entire burn chamber with wood and it produces no more heat than if you had just one stick of wood in there, in a conventional stove the flame is on the top and that leaves  loads of unburnt charcoal but in the Sedore most charcoal is burnt to ash before the next piece drops down.  The third and most amazing feature is if you fill top half of burn chamber with wet or green wood and it will bake to bone dry before it gets to the flame and then it burns clean.  During normal operations its burn chamber fills with smoke before being sucked through the flames and reburnt. The cresote will form on the walls of the burn chamber and it can look 'bad' but its not.  Once all the wood has stopped off gassing the heat of the fire will bake the cresote and it will flake off harmlessly.  Burning off water in the wood takes energy so its always best to burn only dry wood.  But if you dont have enought like I did nt last year then why not!

Lighting the Sedore from cold takes some getting used to. I found the instructions that come with it to be no good.  I finally realized that the stove being an downdraft that the best way to light it is to flip the traditional starting fire on its head.  I put 3-4 medium pieces of dry wood on the bottom (instead of on top), a bunch of kindling in the middle , followed by cardboard and paper. Preheat your chimey then light paper. The draft draws flame down to light cardboard and kindling and then medium stuff.  Once thats burnt down to red embers add big stuff.

Ive kept my Sedore running not stop for a month with only once weekly cleanings using the built in ash grate. You dont have to put fire out before cleaning. Just push embers aside with the cleaning tools provided by the manufacturer.

I did have a scare though.   You are supposed to be able to fill gaps between logs with woodpellets to extend your burn time and last Christmas I decided to do just that.  Well the fire took off on me and even with draft shut down entirely (Sedores are NOT airtight) my chimney pipe glowed red and my chimney thermometer 's needle buried itself past 1900F.  I had to call fire department.  They said if I had waited another 30 minutes I would have lost my house!

Needless to say I called the Canadian manufacturer  to figure out what happened. Turns out my chimney draft is exceptionally good. Chimney is in the house, stove is in basement, house is built into a hill and chimney is at least 40 feet long, all vertical no horizontal sections.  The woodpellets are so dry and so small and draft is so strong it all burnt like a blow torch.  Before I burn pellets again I need to install a damper in chimney.  I dont plan on burning pellets  again until I get too old to cut my own firewood so at least then I will be able to burn  pellets safely.  You are supposed to be able to burn a wide variety of biomass sources but Ive not done so yet.

The other downside is you dont see the flame but oh well at least my house is warm!

I looked into RMHs and while they are interesting I could find no insurer willing to cover my house with an RMH.  So I settled on the Sedore and an insured home.

Wow Jeff,


Thanks a lot for that reply. Exactly the kind of experiential information I was looking for. I also would love to put in a RMH but until I find a way to insure it, it wont happen.

You bought a Sedore model 403 or 4000? Have you contacted sedore usa?

My sedore 2000 easily over heats my 1500sqft home.  If you have a 4000 omg i hope you have a big house!! Or lots of windows to open

I have a model 403 Sedore stove measures 25”x25”x 38” high. Not sure of the new model number but this even has an Alberta serial tag on it so it’s old! The fire box is 14”deep x 23” wide ( inside) by 38” high. I’ve built a hopper 10” deep  x 14” wide by 25” high. Got a good fire going let burn down and set hopper in and filled with dried wheat. Smothered the fire so unfortunately did not work? Any advise?
