Radiator is heating up only to 1/3 of high

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.

What does it mean for " no plumber" please?

This radiator doesn’t put out a great deal of heat and the Amazon description of its heat output makes it seem better than it is.

Well, I think most of designer's radiators would be less efficient than traditional, isn't?

as far as i know, no. got to be the right way,
did you follow instructions on page two?

got to go out work rang

Think he is trying to say that if horizontal you have to remove the blank that will be in the end pipe as it won’t flow it is there for when it’s vertical to assist the flow up to the top and carry on with its convection. Look at page 2 to confirm

We had a job where the customer had a similar issue. In the end we just knocked the baffle out with a length of threaded bar and hey presto they worked perfectly! I think the baffle is there for vertical fit to direct the water round.

That make sense, however is should be better presented in installation manual.

The reseller ignores UK regulations about efficiency information. So why would they produce a decent manual?
