Chimneys

[Leo]

My goal for this summer is get as close as I can to winterizing.,The metal chimney is over priced,lb per dollar.What do they use as i insulator between tubes?going to the center with stove a 20' vertical run.while familiar and owning a tig welder and 20'is a standard length in tube,i trust my self better than x industries.i would weld small spacers to inner pipe how thick? what insulating( no asbestos needed).I heard fiberglass?I can see the advantages of additional heat shields through  the second floor?

Just a couple of air spaces in the triple wall pipe - at least in the ones I've seen.  Stainless steel inside liner.  They just had punched flow through spacers on the end of each section that snapped together.

Thats what i wanted to hear. intesting only the middle is stianless ?Cost?a good metal salvage yard is in order.properly placed venting hole in the outer most tube seems would aid in cooling the tube and would recapture some heat?been surfing the net trying to find that info..thanks

The only good thing about buying the chimney, is you don't have to use up all your round tuits.

I never seem to have enough.

[glenn kangiser]

Seems the commercial ones let air flow through from bottom to top for cooling - It has been years since I did a code chimney.  Mostly mud and rock thimbles now. :-/

That triple wall will seem cheap when your rebuilding and forget insurance , if you want or need it with a home made metal chimney. Just my .02 cents .

PEG's right about that -- make your own and your insurance policy won't cover it.  The triple wall meets codes etc.  And probably a lot of the cost is to meet the $100's of thousands of dollars the testing companies charge to approve a coded product.  Gotta make money to pay the liars I mean lawyers.

PEG's right about that --

Again , I might add    Thank you very much , thankyou ,....  now hold the applause please




Edited to add:

Making rockstars outta carpenters , ah now thats the ticket.

I'll second or third, that on the insurance. That's dangerous ground to be treading on, unless there's no insurance anyway. I'm no fan of the insurance industry, but I wouldn't try making a chimney myself. Are there any inspectors likely to be nosing around? Don't like them much either.

Back home I used a double wall, insulated chimney made by Selkirk. It was all stainless steel. Yes it was pricey. But compared to what?   :-/  Probably going to use the same/similar again.

...just like the price of a ladder.

[glenn kangiser]

The stoves I used to build got a hard won Warnock-Hershey approval as I recall -- very expensive even back in the 70's.  I wonder if testing prices have come down since then. :-?

Note to self--- Send PEG a bigger hat. :-?

Oh come on it's funny , don't ya think  :-/ At least a lil

[glenn kangiser]

I didn't say it wasn't funny.

Good points made,The insurance company's don't like wood stoves.?Time for some competitive pricing both ways..Im not a fan of premium hand man.(insurance),electric and plumbing inspections are all I have to deal with.,the idea 1 piece 20 long heavy inner wall seems it would flow well and be easy to clean..

[builderboy]

My insurance company would totally freak over a home made chimney. Not that you couldn't make a good one, but they don't know and don't want to know if you could. Policy cancelled.

i plan on having four bills monthly .car insurance,electric,water,phone/ Internet.Ive been tig welding in wood structures for decades, not one fire.safety first smoke detectors already in place. My shop in the design stage will be a short walk away probably would give a insurance man a permanent stutter.
