Every machine you build generates heat. Left unmanaged, it builds up — and once a machine crosses its threshold, it shuts itself down. That's the debt.

Two tools keep the debt in check:

Heat sinks — place them near your hot machines and they'll draw the excess away. They read the network they're connected to, not just what's directly under them.
Heat-dissipating boilers — turn that same waste heat into steam instead of just dumping it. Standard vanilla output... at low temperatures.

Works on base 2.0 on its own. With Space Age installed, there's more to find — the boilers in particular behave very differently once you start feeding them serious heat, and the water they use doesn't have to be a one-way cost anymore.

We're not going to spell out the exact numbers here — half the fun is finding out what happens when you push this further than it looks like it should go. Cluster your heat sinks. Feed a boiler more heat than the tooltip suggests it needs. See what the power numbers do.

Compatible with base 2.0. Space Age optional but recommended — it's where this mod was really designed to shine.
