Glad you found the usefulness of bridges in conveying heat.  They are pretty amazing.  

Try using all tempshift plates in the middle (instead of doors), with the same bridge setup as doors, but insert 20kg/tile water (which will rapidly swap to steam once you unpause).

By the time the room with steel doors hit 200C, the room below was at 300C.  I think less steam will do an even better job (as you don't want a large steam battery in the middle). I'm sure someone here could tell us the correct combination of thing to maximize the transfer. 

Trying to improve the speed of heat transfer is a fun problem in ONI. I enjoyed the video.

An interesting and un-intuitive quirk is that aluminum ore bridges can be superior to steel bridges. Multiple cell buildings have clamping based on temperature change. In some (many? few?) cases, this clamping is the limiting factor and not conductivity. In such situations, higher SHC allows more heat transfer before this temperature change clamping kicks in. Of course aluminum ore has a much lower melting point than steel and may not always be usable.

Taking this to an extreme, there are scenarios where shift plates made of dirt or even plastic move more heat than one made of diamond. To confuse the issue even further, some builds may transition back and forth from a conductivity limited regime to a heat capacity limited regime.

Definitely, under the right conditions you can have a plastic shiftplates conduct much better than any other material, with the second best being ceramic. For extremely large quantities of heat, SHC is king, TC is ignored basicly.

As FJ showed in his last video... and when you think about it, it is quite logical... the lower the SHC is, the faster it distributes heat... or at least temperature... cause it isn't able to hold that much by itself, so it has to distribute it faster further. So you have to balance low or high SHC for clamping effects, and distribution.

There's another test you can do to show this.  Build a coal power plant in a CO2 atmosphere.  If you build it out of iron, it will get hot, but the heat will distribute into the CO2 fast enough that it doesn't overheat.  However, if you build it out of copper, or gold amalgam, it will overheat -- even though gold amalgam has a higher overheat point.  (Also: In both cases, the coal plant was running continuously).

The iron one will eventually overheat if the room gets too hot, but the higher SHC allows it to distribute more of the heat into the CO2 than copper or gold can.  The copper or gold coal power plants would overheat while the CO2 barely changed temperature.
