The key to this difference is a series of design choices Miura has made to help increase the fuel-to-steam efficiency of their boilers. For instance, Miura boilers have roughly 10 percent of the water volume of fire tube boilers. This helps reduce the fuel needed to produce steam, boosting the boiler’s efficiency. Miura boilers are also designed to be turned on and off as needed. Conventional fire tube boilers typically run idle when not needed, which wastes fuel without producing steam. However, Miura boilers can start producing steam from a cold startup within five minutes, eliminating this waste and improving fuel-to-steam efficiency.
