upstairs radiator furthest away is only warm ?

[hamster88]

Hi can someone give me some advice, all the radiator in my house get very hot except one, which is only warm.
I have tried bleeding the air out, and it is still only warm. It is the furthest one away from the pump.
thanks

Hi try balancing system

As above. Is it fitted with a TRV and if so is it on the correct way round?

Try turning the rads nearer the boiler down abit and the further one should get hotter

 

[tackleberry]

easiest thing to try first is to shut down all good rads and that will force heat to poor rads then open rads bk up

its an old central heating system. when balancing do i turn the valve going in or out ? Do i leave the hot water in valve fully open but adjust using the cold water valve going out.
