the mini boiler produces steam when attached to things like the inferno forge and hearth, however it is impossible to pipe out the steam since the ouput is on top covered by the multiblock structure, machine accessors do not work for the mini boilers and even though the hearth can have an machine core on the top part, it for some reasons also wont work with the boiler. this could be easily resolved by making the bottom of the boiler a output as well or simply making the machine accessors work with mini boilers
