Woodstove Chimney prices...ouch

I see these concrete block deals for sale at the country hardware store. Are they more expensive?

I was thinking of setting mine right beside the building under the ridge.

Every now and again I see other people have built them.

Sure wish I had a instruction book on building one.

TIA

Sorry, it's your deal, do as you see fit, but my $.02 says "there's a time and place to save money... and this ain't it".

And forget the thru-wall deal. They get cold and draw poorly. Run the correct pipe straight up thru the roof. Yeah, it's more work, but you only have to do it once instead of live with a stove that won't draw for the rest of your life. Be sure to follow the setbacks for your particular stove. Often they are 36" and that makes them unfit for smaller garages.

Me, I'd tell him to keep it, install a $200 electric heater near the ceiling, run the proper 220v service to it, and then turn it on/off as you need it. Unless you spend a lot of time in the garage, this might be the cheapest long-term solution. It also gives you instant heat.

"common sense " and there lies the problem! You can't just have anyone at any time do some tasks without being a danger to themselfs muchless being a danger to there family.

Another consideration is when you insure a structure the insuree wants that install to be too code or when all fails the insuree doesn't want to pay. If you are your own insurrance company then this does not matter.

Example: When I was a apprentice, I built a sheep herders stove for camp. I also made all my own pipe and roof thimble. I had a break down on one of the vechiles and my garage was unheated so I got the bright idea to install the wood stove in the garage as it was cold and the snow was flying.

I cut a hole in my flat roof and made a roof jack for a 12" hole as the single wall stove pipe was 4" diameter so 4" air clearance all around should be enough. I set the roof jack in roofing mastic and shot a few screws to hold it down then installed the 4" stack thru on a china cap (rain cap) and stoked the fire box and lit'er up.

Geezs it looked good with the fire in something I had made with my own hands warming my cold garage so I headed into the house for a cup of coffee with the wife, well maybe brag a tad bit too.

I got to playing with the kids and forgot about my wood stove for about 45mins. I walk into the attached garage and observed roofing mastic running down the stove pipe dripping tar on top of my new wood stove. OOOP's

I was very lucky that the roofing mastic didn't catch fire but it was close as you could hardly breath the air for all the tar smoke.

Lessons learned that day:
Why we need roof thimbles
Why we need double/triple wall pipe
Why I needed to ask a few quesions before starting my next project.

Thoughts 35yrs latter; Why we need building codes was answered 35yrs before.

This was 35yrs ago when there wasn't no stink'n internet :) But I worked for a 250 man sheetmetal shop that had the experts to asnswer the questions I should have asked before starting my project.

And don't forget code calls for the stack to be 2ft above anything 10ft horzontial away from the stack. This keeps the stack drawing as well as keeps back drafts out.

Most people who cheat this part of the code will complain that the stove is smokey and is hard to light duing windy conditions. Depending on just how much the stack is short or near another roof slope will also cause the stack to cerosote the walls easy.

Have you priced triple wall roof thimbles? Shocker No2 coming if you haven't.

Good idea to read up on the fireplace code intall requirments as they keep your family safe. These would be in the NFPC (National Fire Protection Code) book. Your local fire dept. would have a copy.
