Do we need a warm garage....

[RedNeckGeek]

Sometimes you guys scare me...

That remark about the pants came from real life experience. In college I worked part time in a truck body shop as a weldor. On one very cold winter day I was inside a chipper box (the kind they blow the chips into from a wood chipper) welding overhead. About half way through the job I felt something beating on my leg. When I looked down a coworker was trying to put out the flames billowing up from my pants cuff. I told him to knock it off 'cause I was just starting to get warm! :laughing:

You know those flannel shirts with the slick nylon or polyester or whatever lining in the sleeves??? That stuff is highly flammable!!!! Burned the crap out of my arm before I could get if off. Sortta melted to my skin...... Haven't worn long sleeves while cutting or welding since. I'll take the occasional small burn on a bare arm.

Wow, you took this thread about "warm garage" to a whole new level. This is one rare occasion that we can agree on "NO pictures please".

Gives a whole new meaning to nuts roasting on a open fire!:laughing:

I work mostly with metal. After ruining a couple hundred long sleeved shirts and twice catching myself on fire wearing lined flannel shirts, I go sleeveless.

I like working around 50-60 degrees with a shirt, I'd rather have the shirt take the abuse and get dirty. A little welding with a T shirt is ok for a while with small wire, but when doing serious welding, bare skin has to be covered, or arc burn will occur and that hurts pretty bad. When warring a shirt, should be all cotton or even better, something like a Revco shirt, you can look cool while working with heat.

Doesn't anyone wear leather when welding anymore?

Back in another life I was a certified welder and we all had a set of leathers with velcro for the turn up collars to keep from getting arc burn of the neck.

Proper attire was a requirement of the company with included steel toe and shank boots...

Finally remembered to get a battery for my infrared thermometer.

Temps of my stove
Top of barrel = 640F
vertical pipe between barrel and reclaimer = 370F
front face of reclaimer = 260F
vertical chimney pipe at elbow above stove = 220F
outside 10" chimney pipe just above T = 92F

What, where, how, and why does the pipe go out threw the wall instead of threw the roof, purpose of heat reclaimer, besides a 270F drop, which sounds impressive, where did you get it, how highs the shop ceiling? You must have better chimney pipe at 10", mine is only 8".

"Doesn't anyone wear leather when welding anymore?"<<<<<I wear leather bibs when welding overhead, then only if I cant get out of the way of the sparks, and always wear leather when carbon arc gouging on overhead. To reduce neck arc burn, I tape a small piece of leather on the welding hood, other then that full cotton shirts and at my work I also wear flame retarted coveralls, mandatory-ish.

pipe thru the wall = I've never understood why anyone would cut a hole in a perfectly good roof. I built a dual wall pipe thru the wall. My stove pipe goes thru that. No worry of too much heat at the wall.

purpose of heat reclaimer = the temp difference below the reclaimer and above the reclaimer is 150 degrees. Works pretty good huh. If you look at it there are round tubes that go thru the box. Behind the box is a squirrel cage fan blowing air thru those tubes. Thus reclaimer. I'm using that 150 degree heat rather than letting it escape up the chimney. I built it.

shop ceiling height = 10ft at the eave, 12ft in the center. Vaulted ceiling. All steel building.

chimney pipe size = I used what I had. 1/4" wall steel pipe.

The actual temp drop from the top of the stove to the chimney going out the wall is 420F degrees. Even with that I'm a bit disappointed that my outside chimney pipe is still at 92F degrees. But it doesn't soot up so I guess losing that heat is work it.

The through the wall vs through the roof argument will go on forever. It worried me to cut a hole in an almost new roof but the advantages of not needing double insulated elbows and not needing any pipe supports tilted it to the roof. A properly installed roof flashing will last a long time.

 

[ovrszd]

Yeah, no argument from me. Use what works for you. I don't have any double elbows or pipe supports. Very easy to disassemble and clean if needed. Minimal heat loss. Works for me.

My concern is snow accumulation taking out the chimney on the roof. My neighbor down the road had his taken off by snow last winter. He just installed a propane furnace and took the exhaust through the wall. Said he would never go through the roof again. He gave me his wood stove for my new pole barn so now I'm worried about a through the roof chimney. We do get an average of 3-4 foot of snow. Is this a valid concern?

Hopefully those with roof chimneys can chime in with suggestions. That would suck and could be catastrophic.

I don't know how you guys that get that much snow live like that!!!!

My wood burner stack is through the roof been there since 1978. We average over 60" of snow and in early 2000s had over 100" of snow.Most 90+ furnaces will go through the wall cause the cooler warm air does not have the rise. They do have a special stack that can through the roof.

Yeah my 90+ propane furnace in the shop is vented thru the wall with plastic pipe.

When we get temps below 20F and dry air I can shut my wood stove damper all the way and my stove will still draft. So I know my setup works well in that regard. If I was struggling with it I would move to roof exit if I thought it needed it. Otherwise, for me, I just prefer going thru the wall.

Whatever keeps the home fires burning!!! I see you guys getting rain and snow soon.

We are cold enough it'll all be snow. Been spitting off and on for a couple hours. Coming from the South. I just got back from the farm which is 6 miles South of here. Ground is mostly white there. Just dusting laying around here. 21 degrees SE wind 5 mph.

I'm scratching my head on this. We get an average snowfall of 6 to 7 feet per year and usually build up a maximum of about 3 feet on the ground. The pole barn roof gets less buildup because of more heating from the sun and it will slide off. My chimney sticks up about 5 feet above the roof surface. I never notice any snow piling up abnormally around it and I've never heard of a chimney affected by snow.
