-Chimney draft, chimney sensor function test is performed in chimney devices.
– Pre-combustion setting, gas settings under partial power and full power are checked.
– Burner and combustion control is performed.
-Heating and hot water production functions are checked.
– First heat exchanger is checked.
– Electronic parts are checked.
-The dirt traps in the heating and hot water line are cleaned.
– Water switch filter is checked
– Filter cleaning is performed.
– Water flow rate settings are checked.

Boiler Cleaning in Chimney Boilers

-The chimney limit sensor is checked.
– The traction status of the chimney is checked.
– In Condensing Combi Boilers
– The condensation water reservoir is cleaned.
– The sludge separator filter in the direction of the heating flow line is cleaned.

How do we do radiator cleaning ourselves?

Is it possible to clean at home without a radiator cleaning machine? Does radiator cleaning work without the use of medication? We will clarify the questions of boiler cleaning at home.

– Use the nearest faucet in the bathroom to supply water to the installation
– After connecting the mains hose to the machine, fill the machine with water

After carrying out these operations, you can discharge the dirty water that has accumulated in the installation pipes through the drain.

After the dirty water in the installation pipe is cleaned, the cleaning chemical is put into the machine and transferred to the installation.

You can ensure that the chemical substance circulates in the system by adjusting the pressure of the boiler and running it for about 1 hour by bleeding the radiators.
Radiator cleaning chemical substance should be removed from the installation after circulating in the radiators for about 1 hour.
