cold rads down stairs

[cristoforo]

Hi everyone need your expert help again, my rads down stairs are just getting warm and some stone cold, the flow valve on them is really hot but the rads aren't, upstairs they are all hot, could it be the pump on its way out ? (i thought if it was the pump it would be the upstairs rads that would be cool ) i've tried bleeding them but nothing thanks in advance everyone

are they trv's on the rads ?
you thought upstairs would be cold - heat rises.

 

[cristoforo]

no there are no trvs on rads, i thought the pump would struggle to pump it up stairs?
pumps spinning but thought mabye it was wearing out

try checking if the valves are fully open on the cold rads
try the pump on a faster speed, maybe loosing the will to live.

thanks seco ,opened all the vales and pump on fastest speed but when i put it on a slower speed i notice the boiler pressure goes up a little is this normal ?

what is the gauge reading.

 

[cristoforo]

2.0 goes to about 2.3 when i turn pump down

only really needs to be about 1.5.
