Heat Pipe

The Heat Pipe/$ is an insulated core of compressed iron which can transmit heat between blocks, without any thermal connection to adjacent air or fluid blocks. It's a more compact (and cheaper) alternative to using Compressed Iron Blocks/$ to transmit heat. You can conceal Heat Pipes with the Camouflage Applicator/$.
