Hi,

I have recently installed a modern panel radiator in my new bathroom. Like this one here https://images.app.goo.gl/SupNdVUfbBQrQkjW7

Problem is only two of the vertical elements are heating up (one at each end) the top and bottom tubes are also hot.

I've bled the radiator using the bleed screws at the top and only water comes out. I've tried fitting a hosepipe in place of the bleed screw, closed the return valve, and then swapped sides. Still no good.

Any more suggestions?

You may find that your nice new radiator needs to the flow and return to be at specific sides. A lot of these new types of tube rads are baffled internally and need the flow to run in a certain direction, when it doesn't it shortcuts the flow and then a typical symptom is it doesn't heat up in the middle properly.

It should have been marked as such though.
 
As Madrab says, those radiators are often sensitive to which way round they're installed. You might have it back to front, or even upside down (or both). If it's back to front, you have a problem, as you'll need to swap the pipes over underneath, which isn't going to look very pretty
 
On the feed end where the trv is fitted, there is a sticker saying "connection point" and an arrow pointing to the fitting.

If you know the manufacturer and have a contact point then I'd get in touch with them and confirm.
 
Looks like it is connected up backwards. I never knew there was a right or wrong way around for them. Clearly neither did the plumber or the builder.

There's no way of swapping the pipes around now. At least not in the bathroom, may be possible further along under the floor in a different room.

I'm guessing flipping it upside down will not work either. Also guessing it will be difficult to find one the same, but with the flow the opposite way around.
 
Also do you know which is flow? TRV side not necessarily the flow as a lot of valves are bi-directional.
