Building A Garage

[Forzfed]

Then we can argue if it's better to blow the cold air out or blow the hot air down or both:045:

I guess you've never heard of the chimney effect?  It is one of the laws of thermodynamics .

LOLOLOLOLOL

No, it is not one of the laws of thermodynamics!!!!!!!!!

Also, it is properly referred to as the Stack Effect, but, it's still not one of the Laws of Thermodynamics .

Ron, you have me thinking.  If you dig a 40 ft hole in the floor under a radiant heater that is 40 ft above the floor, when you open the cover to the hole, does the air in the building all pour into the hole while the hot air around the heater rises up and goes to the top of the building?  Subsequently, does this result in a vacuum at floor level so all the workers die of oxygen deprivation?

The air across the top of the chimney creates a vacuum[draw] so if you put a pipe to recycle the heat being drawn out and pipe it back into the building at floor level then it would heat the floor space.

IDK Steve ,seems like the air in the ground is warmer than the air above and the air near the roof is warmer than both of those so probably create a sideways tornado

But on a serious note nothing beats the heat from a wood stove.
maybe a pellet stove would work.

[Steve Wood]

Polar vortex!    Pellet stove work very well for sure. I think the radiant heater will work as well unless the interior volume is too great. Insulation will be everything

[bullnerd]

"Insulation will be everything"

I ran my heater a bit over one winter before I had insulation blown in the ceiling. I was really shocked at the difference after insulating. I knew it would be better, but I didn't know how much. 

I think he said no wood or oil? 

[Steve Wood]

Yep

Think of the band CCR and you have conduction, convection and radiation.  Convection is where the chimney effect falls in.  If it makes you feel better you can call it stack effect.

WTF drugs are you on this week? Call in sick until you are clean!

No drugs!  And I got an +A in thermo.  The Engineer that taught me it took all the ASME course's in the States as well.  Most people forget about the zeroth law.

[bullnerd]

Sorry Scoobum...wasn't trying to derail your thread. 

[Scoobum]

No worries dude. I'll post the measurements tomorrow. I'd go wider...but I need some room between the deck and garage. I'm up here in the Great White North eh! It'll be insulated...an d then some. Even gonna grab a garage door blanket.

[Steve Wood]

Bullnerd, you did not sidetrack the convo.  That was Forzfed going off on a tangent about 40 ft ceilings, etc.  He did not seem to get the hints we tossed at him.  SMH.

The radiant heaters that you mentioned are built up in Ontario and I am pretty sure they know what will work and what will not.  Sounds like Brad's shop should be ideal unless he has 40' ceilings.

[Scoobum]

It's gonna be 15x25 to 15x27 with an 8 foot ceiling. Gonna talk to the son-in-law about the length. I'm leaving myself 4 feet between the deck and the garage. My motorcycles are in the shed in the back...and I need room to get them between the deck and garage.
