    How a Water Tube Boiler Works | Miura America

    As the walls of the tubes are heated by the gas, the heat transfers into the water, eventually converting the hot water to steam. While this design is quite common, it is also fairly inefficient for a couple of reasons. First, water is a slow heat conductor, and the more water in the tank, the longer it takes to heat.
