The boiler is delivered to the consumer partially disassembled complete with mounting parts.

The boiler consists of:

corpus;
instrument panel;
level sensor;
smoke exhauster;
remote control;
chimney sections;
spark arrester.

Regardless of what fuel the system is running on, the principle of operation of a hot water boiler is the same: the fuel is burned in the firebox, and through its walls, heat is transferred to the water circulating through the heating pipes. The design of hot water boilers is created in such a way as to ensure the fullest possible combustion of fuel and optimal heat transfer.

Hot water boiler burners differ depending on the type of fuel used. They can be built-in atmospheric, or replaceable supercharged. Built-in burners require only a certain type of fuel to be used. Replaceable burners are more convenient because they allow you to switch from one type of fuel to another.
