How Watertube Boilers Outperform Firetube -

Water tube boilers blow fire tube boilers away in regards to efficiency. Water tube boilers require far less water to function, and at the same time, they also have a higher rate of steam generation than fire tube boilers. This helps to reduce the amount of water and fuel necessary to make a water tube boiler run compared to the alternative option.
