"Firstly did it used to work but has now stopped ?
Does the rad you're bleeding have a thermostatic rad valve ?"
Yes its got a valve with numbers 1-5, and yes it just stopped working about 3 days ago |

Make sure that the thermo isn't stuck ,they some times get stuck .Try giving the metal part of the valve a light tap ,this may be enough to loosen the pin |

Can this light tap lead to flooded house, we always leave the valves on 5 never touch them, so could this happen? and thanks for trying t help me |

first check to see the valve on other end is open the amount of people that dont open them you would be surprised at
heres a way to run it
shut all the other radiators down including your circulator bathroom
leaving the cold one running this forces the water down this radiator only do it for 5 mins though if it dosnt flush through with red hot water into it then its the valves or a bad air lock in it
as the flush through should shift it if it has done reopen the other radiator valves again as they might be some air in the system
sticking valves open to full on give them a spanner knock at valve point where it enters the radiator then screw it down again and repeat a few times this normally losens them
radiator staying cold always in one room becareful of this one if near the bathroom / circulator radiator as if its fully open it will rob from the other radiators as its an open valve
most radiators are set around 3 - 3.5 in each room and its up to them how much more heat they want in a room |

Turn off the valves to all of the other radiators.......... except the one which is cold.
then turn your room thermostat to a high setting, and the thermostat on your central heating boiler also. Turn your contoller to hot water off / central heating on, and this will blast the hot water straight through the cold radiator to expel any air- or sludge which is there.
Once the bad radiator has been working again for a good few minutes, open up the other radiator valves gradually one by one, till the whole system is nicely hot.
If there is a room such a bathroom where a radiator is highest, be prepared to bleed a lot of air out after the purge.
Good luck and happy swinging!   |
