central heating issue

[ShaunCorbs]

Was the trv / non balancing side boiling hot ??

 

[GrahamJ100]

yes the trv side was too hot to touch

 

[GrahamJ100]

and if you put your fingers under the rad u can feel the heat underneath a bit

 

[ShaunCorbs]

Was the other side full flowing ?

 

[GrahamJ100]

not sure what u mean the other side is opened up fully and is stone cold if I disconnect the other side (balancing side ) a load of water comes out of rad and eventually gets warm a little ,a small amount of water ejects from return pipe again cold then goes warm a little

 

[ShaunCorbs]

Yea that's fine so your getting good flow from both

I would say blockage in the rad or pump

 

[GrahamJ100]

the flow pipe and the return pipe from the offending rad comes down my bedroom cupboard the flow pipe is too hot to touch and the return pipe is cold there is what looks to be a gate vale where a pipe connects the flow with the return this is closed I'm assuming it should be closed ?

 

[Harvest Fields]

Have you tried opening it? To see?

 

[ShaunCorbs]

Any chance of a pic of said valve ?

 

[GrahamJ100]

yes have opened it but not sure what its there for ?

 

[ShaunCorbs]

Shut that valve does it heat up ?

 

[GrahamJ100]

valve was shut when all was working ,I have tried it with it open nothing I'm assuming its just there if some work needs to be done on the system above that line ?

 

[Harvest Fields]

Bypass maybe?? Are both pipe below that valve hot?

 

[GrahamJ100]

yes they are both hot left pipe very hot right pipe which I assume is return cold at top warm below

 

[Harvest Fields]

That valve sounds like it is passing mate and needs changing.

 

[GrahamJ100]

which valve do you think needs changing ?

 

[Harvest Fields]

The one with the red wheel head if the flow at return to and from it are red hot.

 

[GrahamJ100]

yes but the pipe on the left of the wheel which is the hot flow is hot all the way to the radiator the pipe on the left is the return which is cold ,the wheel valve is to open the left pipe up to connect to the right pipe I'm assuming if work needed to be done etc ..as I'm assuming this should be closed which it is if I open up the wheel then the hot from the left pipe enters the return pipe this doesn't solve the problem of the hot water going through the rad and exiting through the return pipe ?

 

[Harvest Fields]

Bypass maybe?? Are both pipe below that valve hot?

The question I was asking was are all pipes circled hot?

 

[GrahamJ100]

yes they are all on the left and warm below the valve on the right

 

[GrahamJ100]

if I open that valve up the heat starts to rise up the pipe on the right
but if I'm a guessing man the valve should be shut as the hot water should go up the left pipe through the rad and back down the right pipe ?

 

[GrahamJ100]

so quick update and hopefully someone will know how to fix my problem :: so today I thought id give getting my attic radiator another go if you have read my previous posts you will know that it aint getting warm its stone cold !!
so today I shut all valves down on all my radiators the thermostatic valve and the valve on the left apart from the radiator in the attic I added more water to the system and bled thee radiator till there was water coming out I then turned on the central heating and left for an hr went back to radiator stone cold (it was too hot to touch by the valve ion the right the left hand pipe stone cold so I though I would equalize the remaining radiators when turned on all came on except the one on the landing so now I have to radiators that wont get hot
I'm beginning to think theres an airlock either in the pipes or in the pump ?? was going to replace radiator in attic but now another radiator has stopped I'm thinking its not that the pressure is good and all the other radiators are too hot to touch anyone have any ideas please I'm banging my head on this one

 

[GrahamJ100]

I must add when remaining rads where turned all the attic one was still cold and now the landing one !!

 

[ShaunCorbs]

Best and easiest option would be to try and get a heating engy to have a look at your system

 

[GrahamJ100]

boilers covered but not rads and pipes but yes your right will probably get an engineer in next week many thanks
