How To Flush Out Central Heating Systems
Step 1: Turn off all the electric controls of your heating system.
Step 2: Find protection for your floor
Secondly, place dust sheets or floor protection around the work area to prevent dirt, sludge, or water from damaging floors and surrounding surfaces.
Step 3: Remove one radiator from the system.
Do this move to create an access point for connecting the power flushing machine. Set the radiator aside safely, as it will need to be manually flushed and reconnected later.
Step 4: Connect an inlet hose.
By connecting the inlet hose you will allow water to enter the powerflush so that the system can be cleaned out.
Step 5: Open all radiator valves throughout the property and switch on the power flushing machine.
Allow the machine to circulate water through the system for at least 10 minutes.
Step 6: Drain dirty water from the system.
This allows dirty water to leave the system while clean water enters continuously. Continue flushing until the water flowing from the overflow hose becomes clear.
Step 7: Add the recommended manufacturer flushing chemicals and turn on the machine.
Make sure to have both of the dump and inlet water valves closed. Run the machine for around 15 minutes and change the water flow every few minutes for better cleaning performance.
Step 8: Flush each radiator individually
Close all radiator valves except for one radiator and allow the power flush machine to clean each radiator individually for around 5 minutes.
Step 9: Final fresh water flush
After cleaning all the radiators, pour fresh water and let it circulate through the entire heating system until the water is all clean.
Step 10: Disconnect the power flushing machine and Turn On The Radiator
Switch off the power flushing machine, carefully remove all the valves and turn back on the radiator. Make sure to flush the first radiator we removed before reinstalling it. After the process is finished your heating system should now have clean water running through it and ready to deliver top performance.
Is It A DIY Job?
People think chemical flush is an easy straightforward process, but when they check the mistakes they do and what it can lead to, they step back. And by saying that, we can say that, powerflushing as a more intense version of chemical flushing, requires more professional equipment and expertise on powerflushing, that only an experienced engineer can deliver.
This is why we can confidently confirm that powerflushing is definitely not a DIY job.
