Heat cooler steam to 500°C in this modded Heat-Exchanger.

Major Features:

• Unlocked with Nuclear Energy, placement and usage is similar to regular Heat-Exchangers.
• Sourcing cooler steam can be from waste-wood in burner-boilers, or solar-powered Electric Boilers.

Credits go primarily to Faltease for creating the original mod.

Please see the FAQ, particularly about the [149/s of 103/s] consumption rate in the tooltip. TL;DR, it isn't a bug, nor fixable, nor a cheat.
