The best time to flush your home radiator is when it is warm and just dying out into the cold weather when you will need your heating the most. So here are some instructions in which you can sort this all out ready for the cold weather creeping in.

Then close off the water supply valve for the boiler so that you don’t have any water gushing out at high pressure plus you won’t want the contents of your boiler on the floor. This is usually located on the valve leading to the boiler and may look like a yellow or red handle, it could also be a knob that you turn. Rotate it clockwise to turn off the supply and make sure it is tight.

Once everything is secure open the drain valve on the radiator and allow the water to run out, after this has happened then you can close the drain valve.

Go back and close the bleed screw that you opened previously and open up the water supply for your boiler, allow it to fill and restore the power for the boiler. Then once you have done all of this turn on the boiler and check for proper operation, it is usual for pipes to knock in the restarting of the boiler.

Everything should now be sorted and your heating system should now be working to the correct order, if this is the case well done, if not then consult a professional.
