Apologies for the delay...Computer problems!
Thank you Derek.... I am writing down all your kind comments and will speak to the plumber on Thursday.. Apparently he's been told by Vaillant that the boiler isn't powerful enough! ;((

I don't believe a word of it, how has he and them worked that one out, unless all the 15 rads are 3kws each, I doubt it

This saound like
- unbalanced system or
- air lock or
- not correct pipe size

but I am sure by re balancing the system it should work !

I think you are right, plumber from hell, maybe??? :bandana: bandeedo

Once you've shut down all the old rads that will indicate your problem. But I would put my money on the fact your extension has been piped from too small of a pipe to meet the heat demands.

Hi again
Thank you everyone...I have an update. I turned off all the radiators apart from the troublesome ones..One radiator is warm, not hot whereas the other isn't but the pipes going to it are warm! Sadly not the radiator itself..

 

[SimonG]

Pipeworks too small. Needs repiping back to larger diameter pipework.

 

[lucolivia]

Money outstanding! 😉

 

[SimonG]

You need to give the guy a chance to sort it himself. But def sounds like it's piped incorrectly. If he refuses then you have grounds to inform him that you will get somebody else in to sort the issue and use the outstanding funds to pay for the works. Also that if the works cost more than the what's left he'll have to pay.

 

[SafeGasInstall]

Are thevalves fully open ? Also is te top of the getting worm Orr the bottom ?

 

[lucolivia]

Hi
Just the pipes that come up out of the wall and go into the radiator are warm...The radiator itself is cold ;((

 

[lucolivia]

I think that the valve is open...

 

[SafeGasInstall]

What about the valve on the other side ? It does not matter how bad the system is paiped , rads WILL get hot if all the others are turned off !!!
You need to check the other valve an also let air out + I am sure you have not turn all the others off , pls double check all rads are cold + please check boiler thermostat that is set at min 65 ! If not sure pls stop playing with it and get a plumber in to sort it should be easy to fault find it

 

[lucolivia]

My response was "I think" because the plumber said that the lockshield valve was open. All other rads are cold..We've checked for air.Thanks for your help. I will speak to the plumber

 

[lucolivia]

Finally the radiator is luke warm. The heating has been on for four hours and all other rads were turned off for the duration

 

[SafeGasInstall]

What is temperature set at boiler ? It could be problem with boiler tbh if temperature is set at 60 and rad is not getting hot or there is a blockage or the rev is faulty ! Please remove head of trv valve
