Radiator is heating up only to 1/3 of high

[rafal_22]

Hi to all,

I have bought a new radiator as replacement for old one.


After installation by plumber, the new radiator is heating up only to 1/3 of high. The rest remain cold.
Also, radiator is making quite loud noise when heating up.

The system/radiator is free of air.

My plumber was wondering if it may be a directional type of radiator, but he could not find any additional info in manual or any labels or arrows on radiator itself.

It looks like it it vertical type that can be installed horizontally.

Any suggestion, what can be a problem please?

Maybe someone from forum have already installed this model?


I am not a plumber, by my thoughts are it may be a wrong connection or baffle?

Any suggestion really appreciated.

Are you sure about the horizontal fitting. I would assume with that radiator it would have some type of spreader

did it come with the bleed / seal nut fitted, if not has it been hung upside down,
i"ve only fitted 4 of these and they have had stickers on saying in, out,

Please find photos attached.

There is a baffle in one of the photos.

have you followed instructions on page two?
have you got the flow going in at the correct side of the rad.

There is no labels to tell where is in or out, so assume it can be installed both ways.

You might the look of that, but it has no fins. The claimed output is 6557 BTU but at T60. A mean radiator temp of 80 degrees is crazy hot.

Installed on a new system, designed to regs for flow of 55deg return of 35deg, this radiator would put out 2255BTU, or .66 kW.

B2-EN442 states all hydronic radiator and towel rail outputs are tested and presented at Delta T 50° or ΔT 50°. So an illegal advert in Amazon.
