Overtime your radiator may become clogged up and not perform as well as it used to, this is because of the all the rust particles that build up mainly at the bottom of the radiator and pipes. This keeps your system from working properly and ultimately makes you spend more money because the heating system is working harder and you are seeing no results because of the build-up of debris.so how to flush a radiator
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.
First you should isolate all of the power for the boiler. This is normally located on the boiler itself or you can turn off the power at the central circuit so that you are in no danger of mixing electricity and any water that may leak.
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.
Then you should locate the radiator that is furthest away from the boiler. It won’t necessarily be the radiator that is in need of flushing, it should be however the highest in the system. If you don’t know what this means an example could be if you live in a two story house with the boiler at the back the radiator you should go to first is the one on the second story toward the front of the house.
Then open the radiator bleed screw with a radiator key or an adjustable wrench. Then you should allow the water in the boiler approximately two hours to cool, after this has happened attach a drain hose to the drain on the boiler. Run the other end to a sink or a drain so that the mess is minimal.
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.
If you still seem to be having trouble with getting your radiator working then you can have a look online for some ideas. The internet is a great thing to look at for something like this because there are forums other than this article that feature peoples stories just like yours so you can send and receive messages from someone else who has experienced the same problem as you have.
This way it can also be faster to get on with and find your answer so that you can proceed with fitting the radiator back to the wall, of course use this only if the above steps haven’t worked.
