This is a table of heat conducting speeds for all the elements of Powder Toy.

Heat in powder toy uses this variable to see how often it should randomly calculate heat and apply it to nearby particles.

Heat conductivity ranges from 0 to 250, where 0 is no conduction at all and 250 is guaranteed conduction. Some elements have heat conductivity higher than 250, but this acts the same as 250.

Despite VENT/VACU having conductivity of 255 and HEAC having 251, VACU/VENT are worse heat conductors than HEAC. HEAC has special code that makes it a better heat conductor.
