There are two main ways boilers heat water: fire-tube or water-tube. Fire-tube boilers direct the heat produced from burning fuel through heat exchanging tubes that are immersed in water. Heat moves from high to low temperatures so the water around the tubes becomes hot. Water-tube boilers are different in that there is water inside the tubes that circulates as the tubes are heated from the outside.
Aug 22, 2018 · A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler.

Oct 12, 2016 · Both steam boilers and hot water boilers (also called hydronic boilers) involve the heating of water and creation of steam through the burning of fuel. The heated water is transmitted through boiler tubes, while the steam created is circulated throughout the facility with the assistance of radiators.
The majority of the boilers in the late 1800s and early 1900s were fire tube boilers which operated like water tube boilers except that the hot combustion gases used to heat the water were passed through tubes submerged in water within the boiler. The boilers exploded because they could not be safely pressurized with the existing technology.
Jan 23, 2018 · Boilers are commonly made from steel or cast-iron, and use “fire tubes” which carry hot combustion gases. The burner uses fuel (usually gas or oil) to send hot gases into the tubes. The heat from the tubes get transferred to the water, which is then pumped into the radiators. A flue pipe will vent the exhaust gases out of the home.
The water for a hot water boiler does not need to be potable, but it can still be used as part of a home’s radiant heating system and run through the pipes located in a home’s walls. A boiler will also have an exhaust, much like a hot water heater, that serves as an escape route for fumes created by the gas burner in the boiler.

In fire tube boilers, hot combustion gases pass through tubes submerged in water. In water-tube boilers, the water is contained in tubes located inside a furnace and hot flue gases pass over the tubes, heating the water, and then exit out the stack. While both steam boiler designs offer comparable efficiencies, they are not interchangeable.
