How To Bleed A Radiator

James the plumber explains in this handy and informative video from Trade Radiators, how to bleed a radiator, as well as the reasons for it and ways to hopefully prevent it happening again.
➜ The Complete Guide to Bleeding a Radiator:
www.traderadiators.com/blog/t...
You can tell if you need to bleed a radiator by feeling the heat of the radiator; if it is warm at the bottom but cold at the top, then it means that air is trapped at the top.
There are various reasons for this air accumulating, the most common being that Inhibitor fluid hasn’t been added to the system
water causing it to react to the components inside the radiator and producing hydrogen.
Other reasons for the trapped air is that the pump speed could be set too high so the water is caveating (the molecules are splitting) which produces air, or that work has been recently been undertaken on
the system letting air get in.
Having ensured that the heating system is completely switched off, check that your radiator valve key actually fits the valve.
If it doesn’t then a flathead screwdriver should fit. Open both of the valves at the bottom of the radiator, then slacken off the top valve slightly and let the air escape.
Once water starts to come out of this valve, then you can tighten it back up.
James shows you how simple it is to bleed your radiator yourself, although he does caution to keep a cloth handy just in case you
need to mop up any water that leaks out.
Once you have bled your radiator, don’t forget to close the bottom valves too.
Having shown you how to do this, James also goes through reasons and solutions for if no air and no water come out.
One of the first things that you can check is the pressure vessel for the system as this could have dropped.
To resolve this, you will need to find the filling loop inside your boiler or airing cupboard and open it up until the pressure reads as 1 bar again.
If you have a gravity fed system, then this issue could be caused by a blockage in the pipe from the loft or the ball valve being stuck.
If it is a blockage, you are best to get a professional in.
If you find that you are having to frequently bleed a radiator (or radiators) and it’s a chronic problem with your heating system, then the best thing to do is to call in the plumber who originally fitted it
who should be able to solve the problem for you.

What do i do for creeking, noisy pipes?

[@daveboy1247]

i have a problem with a radiator in my hall.
i got new radiators installed and a central heating temperture dial as well put in which is on my wall.
now the council removed my gas fire and put in a electric fire and gas radiators.
the radiaor in the hall does not have a dial on the bottom of it that allows you to turn it off at the radiator or turn it down.
the gas men told me i had to have this one and you can not turn it off , so if i only have my bedroom radiator on, the radiator in the hall will be on as well.
the radiator in the hall is cool to the touch except for the bottom.
why is it cool to the touch as if i can make it more warm, will this cost me more money.
i was told that this is a by pass radiator and if i can make it more warm, will it cost more money to run.

What would happen if i did this while the radiator is running?
