Fundamentals of water for Boilers - Yamatho Supply LLC

Oct 25 2016 · Water â an ideal medium for carrying heat energy. It takes one BTu (British Thermal Unit) to raise temperature of one pound of water 1oF. It takes an additional 970 Btu to change one pound of water at boiling point to steam. This heat energy is stored in the steam and when it condenses the energy is given off.
