Lukewarm radiators

ukmanimal100 · 24 Jun 2007

I have added 2 new radiators to my CH system and they are both lukewarm at best. One is downstairs (using 15mm plastic pipe), the other upstairs (on 10mm copper)

Both have new valves, are free of air, and run clear when you drain them so I don't think there is any sediment in them.

The "in" pipes to both rads are piping hot, but beyond the valve, it is lukewarm, and the "out" pipe is often cold to the touch.

Anyone got any ideas why this is happening, all other rads on system are burning nicely so I am at a loss. Have I overloaded the boiler ? The manual says I am well within the btu's allowed, could the pump be dodgy ? I am running at a working pressure of 2.5mb at present.

All advice gratefully received

a working pressure of 2.5mb????????????????????????

HOLY EFFFFFF thats unbelivably low

i take it you dont know your harris from your elbow with gas? If i am right leave it the heck alone!!!!!!!

as for your problem try running the boiler in CH only and turn off all the rads other than your new oness

PS how did you check the test nipple for gas tightness???

1. Turn off all rads except ONE of the cold ones.
2. Do the same with the other.
3. Stand back in amazement.

CM I spect ee means 2.5 bar..

In which case, OP, bleed a rad to get it down to 1.5 bar.
Then look in faq for Balancing.

Air lock in the return from the new rads.

I'm sorry to be the bringer of bad news but your problem is caused by faulty installation. The only remedy is to remove the new rads and associated pipework, and make contact with a Corgi registered heating engineer who will arrange to reinstall the rads at reasonable cost. I can pop round and give you a quote if youre local to the Bristol area.

Hope this helps!

Really? Which part of the installation is faulty?
