1. Control panel: It is the electronic box that blows the boiler. It controls when the gearbox, motor, fan, pump
stop and when to run. The temperature values read while controlling are effective.
2. Geared motor: It is used to increase the power by decreasing the speed of the motor. The movement of the
auger gives the gearmotor. The safety device in the pellet feed line also gets its movement from this
gearmotor.
3. Fan: It is the fan that provides the combustion air. It can be adjusted to operate at the desired speed from
the control panel.
4. Hot water flow line: It is the flow pipe to the radiators or heating system. The water heated in the boiler is
sent to the radiators or heating installation from this pipe.
5. Return line: It is the pipe through which the water returned from the radiators or heating installation returns
to the boiler. It can also be called return pipe or return line.
6. Safety flow line: It can also be called expansion line. It is the line where the expanded water is sent as a
safety due to heating in the boiler.
7. Safety return line: It is the line where the water sent from the boiler to the expansion tank is taken back.
8. Hopper: It is the place where the fuel is stored. The power it can take depends on the fuel size.
9. Water jackets: These are specially designed water chambers to circulate the water and circulate the smoke.
As the smoke passes between them, it releases its energy and heats the water inside.
10. Grid: These are the pipes used for burning wood. Water passes through the pipes. In this way, both the
water inside is warmed and the life of the grid is extended.
11. Pellet burner: It consists of two nested chambers. Pellet fuel is driven from the inside by the helix and the
air coming from the outside is blown by the fan. Fan air and fuel meet at the front of the burner.
