Boilers, also known as water heaters, are plumbing materials that heat and store water through a coil or resistor inside. Boilers are classified into three categories based on their structures.
- Single Coil Boilers: Water heating is provided through a single coil.
- Double Coil Boilers: Heating is provided through a double coil.
- Electric Boilers: Water heating is provided through electric energy.

Boiler Selection and Usage Areas
Boilers are generally used in central hot water preparation systems in places where people live collectively. Coil rapid boiler types are used in mass housing areas and should not be confused with household boilers. Household boilers are individual usage oriented, so their volumes and water heating capacities are much lower.
The main areas where boilers are used for heating water are as follows.
- Hospitals
- Schools
- Shopping Malls
- Hotels
- Dormitories
- Construction Sites
- Apartments
- Residential Complexes
- Factories
How is Boiler Selection Made?
The most important criterion in selecting a boiler is the usage area. Boiler selection should be made by mechanical engineers based on certain criteria. Boiler selection is made according to the conditions of the Chamber of Mechanical Engineers based on the hot water needs of mass housing areas. The calculated data includes the amount of water needed per hour and all water usage sources (faucets) are calculated by considering them open for one hour. In short, boiler selection should be made based on the hourly production value and the simultaneous usage factor.
