Nuclear Energy Storage: Heat Pipes VS Steam Tanks :: Factorio General Discussions

1x full storage tank of 500deg steam = 2.425 GJ of energy. Heat Ex & Heat Pipes store up to 500MJ each. Each Reactor Core stores up to 5GJ. Realistically you would not want the HX, HP, & cores at max temp (probably = wasting fuel). However, as they do store a fair amount & you always need to build some anyway, it means you need less steam tanks ...
