I am very much missing a finer degree of heat management than "match the correct heat pipe with the respective building" based on max temperature.
I would be really excited if each building had it's "minimal" (20), "ideal" (60) and "maximum" (120) temperature, where getting close to the ideal gave it a bonus (e.g. crafting speed / productivity).
If there was some heat pipe shutoff, controllable by circuit network, and a way to read heat using circuits (possibly on the same shutoff structure?), it would make controlling the heat way more fun.
