Radiators Cold in Back Half of Bungalow

[Matwek]

Hi, I'm looking for some advice on my heating.

We live in a 3 bedroom bungalow with the main two bedrooms at the back of the house.
All the radiators in the rooms at the front of the house seem to work fine but as you travel back into the house they get colder and colder, until you reach the back room where they're barely on at all.

Having done my own bit of research it seemed like the problem could be solved by taking a look at the Lock Shield and attempting to rebalance the system.
But after taking a closer look at my radiators I couldn't find anything resembling a Lock Shield.
I've attached an image of both ends of the radiator...

Side Note: I did take a look under to temp control to see if that had got stuck but that was working fine.

Any advice would be greatly appreciated.

2nd photo is lockshield. Look for croppies balancing thread.

Brilliant, thanks.
I did think it might have been but it looked different to every other one I came across online.

If this has just happened i.e . It was ok last year, its got nothing to do with balancing, I would look more at the pump or a blockage

We moved in a couple of months ago and its been an issue since day one. Only just got round to sorting the issue.

The house had been left vacant for a good few months before we purchased the property though.

You could also take off the trv heads and let the heat in properly...trv are rubbish intermediate tech. Fail,often
Are expensive and only sold by installers and merchants to make more profit . A properly
Balanced heating system will be way better and more efficient

So you have inherited the problem , great , not !!
Try turning off the rads that work and see if the other rads that dont , warm up .
As for the comment above about TRV’s please just ignore it .

Ok we will agree to,differ my friend ...it’s a technical and commercial,matter and I like this engineer ..trv are rubbish !

Thanks. I'll try that.
By turning them off do you mean with the TRVs or via the lockshield?
If I need to shut the lockshield off I assume I need to turn this part at the top?

No just trvs don't touch lockshields , also take off the trvs ( for the moment) in the rooms that dont heat . Carefully push the pins under the trys to check they arent seized.
