Translations:High Pressure Coal Boiler (GregTech 5)/14/en

Water can be added to the boiler by right clicking on the machine with water buckets, or by placing any sort of cell with water in the water input slot in the GUI. Like all GregTech machines, it will give the empty cell back. If the temperature is above 100 and the boiler runs out of water, adding water will cause an explosion, so wait for it to cool off first.
