outdoor wood stove air heating - what material to make pipe out of?

Hi, I wanted to use some steel sheeting to make a small frame around my wood heater stove in the garage for the purpose of piping hot air into the house.

In the attached photos you can see the intake and out, but I want to make this pipe go and zig zag right around the top / around the wood fire stove. Thus these pipes will get VERY HOT.
My main concern is them emitting some sort of toxic fumes. As this air will be taken in outside, circles around the the wood stove and taken into the house.

Does anyone have any recommendations on the best pipe to use for this? I was looking into ceramic tubes.. or just steel pipes. I just want to make sure the air flow will be safe under very high temperatures.

Thanks, any advice would be appreciated.

I'm no expert but I'm thinking about doing this same thing and if I did it I would look into using insulated chimney pipes. But I'd research the whole of gassing thing first of course.

Gassing thing?

Id imagine cast iron pipes should work too as they are used in the heaters themselves right? If the heater gets that hot then you would be breathing the air around it that would be bad otherwise.

Well, the air in the pipes shouldn't get very hot, so basic zinc coated hvac ductwork should work.
The surface of a wood stove might be 600° while Zinc coating melts around 900 ˚F and vaporizes at about 1650˚F.
If it were my build, I would burn  the zinc off in a bonfire before installation.

This has been done before.
They make heavy mass outdoor burners that pipe the hot air indoors, some heat water, and pipe it indoors for heat.
These are notoriously smoky creosote-producing stoves.
You will see them smoking/choking all over the upper Midwest.

To get the air indoors you need large diameter insulated buried pipes and fans to move the air.  Heat loss on exposed pipes would be excessive.
Trying to push through small pipes might not work very well.
Electricity is required to move that air.

Is your garage wood stove built with heavy metal?  It may get too hot inside its sheet metal box and start to warp...
How far is it from this stove to your home?

I suggest learning about and building a Rocket mass heater and having no fire at night at all.
