Classification of Boilers: Learn About Each Type of Boilers

Boiler is a closed vessel where heat is generated by the combustion of fuel. The classification of boilers is based on several factors and is classified into six categories: According to the contents of the tubes, the number of tubes, the position of the furnace, the axis of the shell, methods of circulation of water and steam, and the use.

The term "kilowatt" is used by heating professionals to describe how much heat energy your boiler produces. According to the general kW rule, you will need a higher kW boiler the more heat and hot water you need for your home.
