radiators

[lewis1979]

Hi, i have 2 radiators in my system not working!

Thought it might have been a faulty TRV so changed the TRV but still the radiators are still not warming up!!

When i bleed the radiators in question water does escape so water does get to them!!

Have also tried adjusting the pump speed

Id be grateful if anyone might have any sugestions

Thanks Lewis

 

[cross thread]

are the lockshild valves open?,failling that sounds like a blockage .are they on plastic pipe

 

[lewis1979]

lock shields are open, dont know if the pipework under the floor is plastic but the pipes connecting to the radiators are copper

if it was a blockage would that not prevent the water getting to the radiators? they are filling up as it was a brand new radiator i also installed so know it was completely empty

if it is a blockage how would i clear that?

turn all other raditators off
and then see what happends
and if ur boiler is on sealed system put the pressure up

turned all other rads down, but one of them doesnt have a TRV or a plastic c ap on to indicate which is flow or return, how do i find out what one is flow?

If you can't tell, it doesn't matter!

CLOSE ALL of the rads which DO get any heat in them. If that makes the cold ones heat up, it's aquestion of Balancing - look it up. If not, it's SLUDGE, have a beer before you look that one up.
