Hey, I like this mod - it makes an alternative use for boilers which can broaden the game.
But you still have an efficiency of 1 on the boilers and it doesn't work. I can make a perpetual energy machine with a pump, a boiler, a steam engine, and an insert. You just need to jumpstart it.
Without an efficiency, I just feel like I'm cheating my way out of accumulators.
Please just give it a flat 50% or something. Or let us change in mod settings.
