Firetube Boilers vs Watertube Boilers: Which Is Right for You

In a watertube boiler, the heating element acts directly on tubes filled with water, which run through the furnace casing, to produce the needed steam or super-hot water. In a firetube boiler, the heating element produces hot water through a more indirect mechanism. The hot flue gases generated by the boiler’s combustion are channeled into tubes and routed through a water tank, and the heat transfer from these “firetubes” creates the needed hot water or steam.
