Is it possible to bleed these rads?

[stratplus]

There’s a finned element along the bottom.

 

[ShaunCorbs]

yes its an lst rad one of the panels should come off

Probably inside the casing at the top of the finned element. Just need to work out how to get in.

There was a screw at the top left (and top right I think) which I couldn’t gain access to due to the wall.
So if I can remove the top there should be a bleed nipple on the element/valve somewhere.

Never seen LST’s like this one. Any idea of the make so I can look them up Shaun?

It might be a jaga but I will have a sift through my books

I can't see close up on photo but if it's what I think it is there are two screws at the top on each side just beneath the top of the plastic strip. Take those out and the top will come off. then the front sections/panels are slotted together.

Only take as many out as necessary because it can be a pig to reassemble. There should be an air tap on the top right front of the finned rad inside.

Are you sure it needs bleeding?
Done many Jaga and the like elements.
Due to the low water content and the design of the flow through element, they very rarely need bleeding.

What's the problem with the heater in your view?

They weren’t getting very warm. Someone has repaired leak on boiler and probably haven’t vented when topping up. Flow and return piles to and from rads were fairly hot. Return probably not so much.
I cleaned the fins with a brush, not sure that helped.

Yes, screw either side but right hand screw unable to access as too tight to wall.

Could be Sean, I have downloaded some info on Jaga rads and looks about right or very similar.

Or not tried hard enough!
Now I know a bit more about them I can sort them out.

I though these were really old rads but looking at the info it seems not.

I'd guess less than ten

I would be surprised if they were older than 5 years tbh

They are natural convectors, the surface of the casing doesn't get hot like a traditional radiator.
The casing doesn't do much besides covering the element and creating a chimney effect- the higher the casing over the element the greater the convection & heat output.
