Keystoker Koker Furnace

A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

Please help! My husband and I just bought a Keystoker Koker Furnace and had all the duct work ran through the house. Before we could havei t tied into the chimney we had to have it swept, thats when we got the news that it has 2 cracked flues. We have been calling around trying to get some answeres on the best way to go, and we have been told so many stories and they are all conflicting. My husband has been trying to reach the actual manufacturer but has only been able to get as far as leaving messages and fax tones. Can some one please tell me the best way, the safest way, and the most cost efficent way to vent this unit? It is installed in our basement. Thanks.

I moved this topic to Coal Stokers: Boilers, Furnaces and Stoves you will probably get more answers there .

You know when people say it was "better back in my day"?

They were right.

Sorry to hear this.

I have a koker and am using it with a 5" 316 SS liner up my chimney as my flue was cracked also.

Seems you either need to fix the chimney, put in a liner or get a direct vent system out the basement for the koker.

You will love the koker once you get her up and running!

Anyway, any questions let me know. I have had mine now for 3 years and it is awesome.

Check this link out. Locate a chimney sweep in your area who has worked with this. May save you a bunch!

Can you be more specific than "cracked flu"? Are the terra cota tiles actually broken, or is the mortar missing between some of them?

Something you may want to do is run stove pipe out the thimble and see if you can get draft. And like Markvii asked is is just a little morter out, or whole pieces of terra cotta gone?

You definitely need to find out exactly what is wrong with the chimney, if it can be repaired I would go that route. A masonry chimney is the way to go if you have one. Just be careful, "Chimney Specialists" are a dime-a-dozen and there are those individuals that operate on the basis that the homeowner is clueless and scared of CO poisoning and fire. Get a few different companies to look it over, ask for references. With today's technology a small camera can be lowered down the flue and you will be able to see exactly what's going on in there.

Also, is it an Interior or exterior Chimney? If it's an exterior chimney, a couple cracks may not be a problem.
