Radiant Pipe best material?

[Denisetwin]

I thought I saw a post re: best materials to build radiant pipes, but can't find it now and not sure if it was before the recent updates to radiant pipes anyway.  My questions is, what is the best material to build radiant pipes in two different scenarios:

1.  I want the room that the pipe is going through to change temp, ie I want to cool down a room using radiant pipes

2.  I want the element in the radiant pipe to change temp, ie I want to either cool down or heat up the element that is IN the pipe

Maybe the answer is same for both?  I know before radiant pipes it was granite for one and wolframite for the other, trying to find the "new" answer.

Actually before it was wolframite and now it is wolframite too but with two improvments. The radiant pipes themselves and the fact that heat exchange uses an average conductivity between two materials now. So you get more out of using conductive materials.

But gold liquid pipes should be better than tungsten for most heat exchange cases

Right, in terms of liquid pipes gold is the fastest exchanger because it has the same conductivity but a slightly lower capacity. I was mixing it up with gas pipes, where you want wolframite.

So tungsten is useless for heat exchange now?

Tungsten has a very high melting point. It is needed around volcanoes and magma where gold may melt. Iron is more common and has a higher melting point than gold but slightly worse conductivity. Each has its places.

Because devs only said they change how the thermal conductivity influence heat exchange, I still hold my old view.

 

 

When liquid in pipes are colder than surroundings, the heat transfer ability depends on the thermal conductivity of the pipe.
 

When liquid in pipes are hotter than surroundings, the heat transfer ability main depends on the thermal conductivity, and then depends heat capacity of the pipe.

Tungsten and gold have almost the exact same properties, Gold is just slightly faster because it stores a bit less heat. They are actually interchangeable in almost all contexts.

Hmm, that's pretty lame. No point in using tungsten at all. So gold is better for shift plates too @clickrush

Not necessairily. If you want a bit more stability then you rather want a higher capacity. Allthough in this case diamond/iron would be even better. But again, the properties for most cases are almost identical with tungsten and gold. I personally prefer to save wolframite in its raw form to build machines/doors where I need higher conductivity though, because wolframite is more precious than gold amalgam.
