Overview of Steam Boiler
A steam boiler is an apparatus designed to produce steam by heating water. It acts as a heat exchanger, transforming water into steam for a variety of external uses. The boiler typically contains a combustion chamber alongside a water reservoir. Steam boilers are available in different sizes, from compact units to sizable versions capable of undertaking more intensive operations.

Common types

Hot Water Boiler
These boilers are usually made of aluminum, stainless steel, steel, or iron because they are resistant to high temperatures and pressures. This type is further divided into water-based or fire-based tube systems.
Electric Boiler
This boiler uses electricity to generate heat, making it faster and more efficient at heating water. This type is highly durable and more environmentally friendly than fossil-fuel burning boilers.


Oil Boiler
This type uses oil as fuel in the combustion chamber. Oil boilers are considered more efficient than gas boilers because they are more durable.
Gas Boiler
Unlike oil boilers, gas boilers use natural gas or propane to operate. This type is suitable for industrial and low-pressure applications.
