Boiler tubes are broken into classifications. There are tubes used for water tube boilers which are highly thermally efficient but because they are harder to build, more expensive than fire tube boilers. With water tube boilers, only water flows through the boiler tubes. Then there are tubes used for fire tube boilers. Hot gasses pass through these tubes. These boilers are easy to operate and marginally inexpensive to purchase.
